Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road surface anti-icing block and a block road surface using the same, and more particularly to road surface anti-freezing, which is particularly liable to freeze in cold regions such as winter and requires special attention in terms of traffic safety. The present invention relates to a road surface antifreezing block suitable for countermeasures and measures for preventing road surface crushing where snow removal work is frequently performed, and a block road surface using the same.

2. Description of the Related Art Conventionally, asphalt road surfaces and concrete road surfaces are frozen in cold regions in winter,
There is a problem that it becomes an ice burn on the smooth road surface. On an ice-burned road, it is difficult to operate the steering wheel, and the car may make a sudden turn in an unexpected direction, the tires may slip and the brakes may not work, and collisions and rear-end collisions may occur. In addition, pedestrians can easily slip and fall on pedestrian crossings, which can be dangerous and can even cause bone fractures.

As a measure for solving such a problem, conventionally, for example, an intersection, a steep slope, a bridge, a shade,
Anti-freezing agents and anti-slip materials are sprayed in places where accidents are likely to occur when the entrances and exits of tunnels are frozen.
In particular, since spike tires have been banned recently and studless tires have become the mainstream, anti-freezing agent spraying at intersections has been strengthened as a measure against slip accidents in urban areas.
Anti-freezing agents include sodium chloride and calcium chloride, as well as acetates, etc. that consider the effects on the environment to lower the freezing point and suppress road surface freezing. Fine sand or crushed stone is used as the non-slip material. These are sprayed with an antifreezing agent when the temperature is minus 8 ° C or more during the early winter or the end of winter, or when the road surface becomes an ice plate or an ice film, and the temperature is minus 8 ° C. Non-slip materials are sprayed during the following periods and when the amount of snow and snow on the road surface is large. In this way, road surface freezing measures are taken according to the time of year and road surface conditions.

At major intersections in urban areas, pavements on shopping streets, etc., road heating is installed to directly warm the road surface and prevent freezing.

However, in the above-mentioned measures to prevent freezing of the road surface, many workers are required for spraying the anti-slip material and the anti-freezing material, and since the spraying work is performed mainly at night, There is a drawback that the burden is large. There is also a problem that the snowmelt water will freeze again if there are few pedestrians and vehicles coming and going even if sprayed.
In addition, antifreeze materials may be harmful to bridge structural members,
There is concern about the impact on the surrounding environment. Also, the anti-slip material has a bad reputation because the roads and shoes are dirty.

On the other hand, when installing the road heating, there is a problem that the installation cost is too high and the running cost of electricity, oil, etc. is high, so that it is too expensive to install in a wide range.

In order to solve such a problem, the inventor of the present application has proposed the invention of utility model registration No. 3083434. The present invention is to lay a block provided with a buffer plate on a road. In other words, by laying a non-freezing buffer block, in which an elastically deformable buffer plate is sandwiched between the upper block and the lower block, on the road, pedestrians and vehicles can pass over this anti-freezing buffer block. The buffer plate contracts due to its weight to generate a step between the blocks, thereby crushing the frozen ice plate on the non-freezing buffer block. This eliminates the inconvenience of the anti-slip material and the anti-freezing agent, and the anti-freezing measure can be taken at a lower cost than the load heating. Furthermore, even if a pedestrian falls on the antifreezing buffer block, the buffer plate acts as a cushion to prevent serious injury.

On the other hand, as another conventional road surface anti-icing method, a block in which a rubber processed product is slightly projected from the road surface is laid, or a block in which crushed rubber is mixed is laid to prevent slippage. May be fulfilled.

[0009]

However, the above-mentioned protruding portions and uneven surfaces of the rubber processed product formed on the road surface are scraped off by a snow removing plate such as a blade or a snow plow during the snow removing work by the snow removing vehicle. It is often crushed, and there is a problem that repair costs a considerable amount of money and waste, and is inconvenient for transportation. Such a problem may occur also in the block including the above-mentioned cushion plate, and a step between the blocks caused by the contraction of the cushion plate may be scraped off by the snow remover of the snow removal vehicle.

On the other hand, when laying a conventional block on a road, since joints with adjacent blocks are jointed, rainwater and snowmelt water do not permeate underground and freeze on the road surface. There is also a problem.

The present invention has been made to solve at least one of the above problems, and prevents a slip accident of a vehicle by crushing a frozen ice disk formed on a road surface in winter. , It is possible to prevent the uneven part of the road surface from being scraped off by the snow removal plate of the snow removal vehicle during snow removal work, and also to prevent rainwater and snowmelt water on the road surface from returning underground and this The purpose is to provide the used block road surface.

[0012]

A feature of a road surface anti-icing block according to the present invention is that a block laid on a road is composed of a lower block and an upper block, and an elastically deformable elastic member is narrowed between the blocks. A road surface anti-icing block to be held, wherein the upper block overlaps with another road surface anti-freezing block adjacent to the horizontal direction and overlaps with another road surface anti-freezing block to press the upper block downward, another of the pressed portion for pressing part of the road surface freezing prevention block is pressed into the superposed with lower that are at least one of forming, the pressing
The part is formed on the front side with respect to the traveling direction of the vehicle traveling on the road.
And the pressed portion is rearward with respect to the traveling direction.
It is in the point of being formed .

By adopting such a configuration, the weight of a vehicle or the like can be adjusted by appropriately adjusting the position where the road surface antifreezing block on which both the pressing portion and the pressed portion or one of them is formed is arranged. Is added,
The elastic member contracts so that adjacent road surface anti-icing blocks do not sink together to create a step, or only one of them sinks to create a step. When a step is generated between the adjacent road surface anti-icing blocks as described above, it has an effect of crushing the frozen ice disk on the block. In addition, when no step is generated, that is, as one road surface anti-icing block sinks, at the same time, the pressing portion of the upper block is pushed down to press the pressed portion of the road surface anti-freezing block that is adjacent to the adjacent road surface anti-icing block. When the road surface anti-freezing blocks both sink and do not cause a step between the blocks, it is possible to prevent the snow removing plate from moving forward and being scraped without hitting the block even if the snow removing vehicle passes through. Furthermore, in the traveling direction of the traveling vehicle

[0014]

Further, in the present invention, it is preferable that the upper block is further formed with the pressing portion and the pressed portion in a direction orthogonal to the traveling direction of the vehicle. And by adopting such a configuration,
Prevents steps from being created between adjacent road surface anti-icing blocks that intersect in the direction orthogonal to the vehicle traveling direction, to maintain smooth running of the vehicle and to prevent lateral road surface anti-freezing by the snow removing plate of the snow plow. It has an effect of preventing the block from being scraped. Further, even when the vehicle is traveling in a direction different from a predetermined traveling direction such as when the vehicle changes its direction, it is possible to prevent a step from being generated in the traveling direction.

Further, in the present invention, at least the chamfered portion is formed by chamfering the upper edge of the pressing portion, or the chamfered portion is chamfered at all of the upper edge at the road surface forming position of the upper block. Are preferably formed. By adopting such a configuration, even if the vehicle traveling on the road surface anti-icing block travels in the direction in which a step is generated between the adjacent road surface anti-icing blocks, such as when backing up, the tire Does not contact the edge portion but contacts a chamfered portion having an inclination and moves to the adjacent road surface anti-icing block, so that an effect of less impact is exerted. Further, since the chamfered portion is formed, a groove having a fine width is formed on the road surface, and when the vehicle travels in the groove portion, the tire is slightly vibrated from the groove. Therefore, it is also useful as a road that calls the driver's attention in a specific section where special attention needs to be paid to excessive speed, such as a curved slope of a pass. In addition, it also has an effect of guiding rainwater and snowmelt water on the road surface to the underground through the groove to reduce the water.

Further, in the present invention, it is preferable that the pressing surface of the pressing portion of the upper block and the pressing surface of the pressed portion have substantially the same shape. By adopting such a configuration, the pressing force can be effectively transmitted from the pressing portion to the pressed portion, and when laying each road surface anti-icing block, it is easy to determine the arrangement position and the arrangement direction. Thus, the work can be smoothly performed.

Further, in the present invention, it is preferable that a through hole that penetrates from the upper block to the lower block is formed in a height direction of the road surface anti-icing block. By adopting such a configuration, rainwater and snowmelt water on the road surface antifreezing block can flow downward from the through holes, so that hydroplaning phenomenon on the road surface and refreezing of the snowmelt water can be prevented. Have. Further, this through hole also serves as a relief that absorbs the deformation when the elastic member is compressed, so that the elastic member is prevented from jumping out from the upper and lower blocks, and the adjacent road surface freeze prevention blocks are It has the effect of moving up and down without disturbing each other.

Further, the feature of the block road surface according to the present invention is that the pressing portion of the road surface antifreezing block according to any one of claims 1 to 4 is covered by another road surface antifreezing block adjacent to the pressing portion. The point is that they are aligned so as to overlap the pressing portion. And by adopting such a configuration, when the weight of the vehicle is added,
It is possible to obtain a block road surface in which adjacent road surface anti-icing blocks do not sink together to cause a step, or only one of them blocks to cause a step. Here, when there is a step between the adjacent road surface anti-icing blocks, there is an effect of crushing the frozen ice disk on the road surface of the block. In addition, when there is no step, that is, as one road surface antifreeze block sinks, at the same time, the pressing portion of the upper block pushes down the pressed portion of the adjacent road surface antifreezing block, thereby adjoining. If the road surface freeze prevention blocks do not sink and there is no step between the blocks, it is necessary to prevent the snow removal plate from moving forward without hitting the blocks and scraping the road surface of the blocks even if the snow removal vehicle passes by. You can

In the present invention, neither the pressing portion nor the pressed portion is formed in the vehicle traveling direction at the center line position of the road, and only the pressed portion is formed in the direction orthogonal to the vehicle traveling direction. Arranged road surface anti-freezing block, at the widthwise both ends of the road, the pressing portion is formed on the front side in the vehicle traveling direction, and the pressed portion is formed on the rear side, and A road surface anti-freezing block in which only the pressing portion is formed is arranged on the center line side in a direction orthogonal to the vehicle traveling direction, and the front side in the vehicle traveling direction is pressed at an intermediate position sandwiched between these two arrangement positions. Part is formed, the pressed part is formed on the rear side, and the pressed part is formed on the center line side and the pressed part on the end side in the direction orthogonal to the vehicle traveling direction. It It is preferable to dispose the road antifreeze blocks are.

By adopting such a configuration, even between the road surface antifreezing blocks in the direction orthogonal to the traveling direction, adjacent road surface antifreezing blocks do not sink together to form a step, or It is possible to obtain a block road surface in which only one sinks and a step is created. Therefore, when the vehicle travels, the steps are prevented from occurring on the front side even on the left and right in the traveling direction, and the smooth running is maintained and the snow removal plate of the snow removal vehicle prevents the steps from being destroyed. Further, on the rear side in the traveling direction of the vehicle, there is an effect that the frozen ice disk is crushed so that steps are sequentially formed on the left and right sides of the traveling direction.

Further, in the present invention, it is preferable that each road surface anti-icing block is arranged so as to be movable up and down without filling a joint between adjacent road surface anti-freezing blocks.
And by adopting such a configuration, it is possible to smoothly move up and down without rubbing between adjacent road surface anti-freezing blocks, and to prevent rainwater, snowmelt water, etc. on the block road surface from the gaps. It also has the effect of discharging downward.

BEST MODE FOR CARRYING OUT THE INVENTION An example of an embodiment of a road surface anti-icing block 1 according to the present invention and a block road surface 9 using the same will be described below with reference to the drawings.

FIG. 1 shows a road surface anti-icing block 1 according to the present invention.
FIG. 2 is a perspective view showing an embodiment, and FIG. 2 is a perspective view showing a part of a block road surface 9 formed by laying a plurality of the road surface anti-icing blocks 1. FIG. 3 is a top view showing an example of a road surface on which the road surface anti-icing block 1 is laid.

Road surface anti-icing block 1 according to the present embodiment
Composes a block laid on the road by a lower block 2 and an upper block 6, and an elastic member 3 which is elastically deformable is sandwiched between these blocks. The upper block 6 is provided on the first upper block 4 on which the first pressed portion 4a and the second pressed portion 4b, which will be described later, are formed, and the first upper block 4 is provided on the first upper block 4 and protrudes in the horizontal direction. The pressing portion 5a and the second upper block 5 on which the second pressing portion 5b is formed are integrally molded. In addition,
In the present embodiment, the upper block 6 is integrally molded, but the first pressing portion 5a and the second pressing portion 5b are separately manufactured, and are integrally formed by bonding with an adhesive material. Good.

First pressed portion 4a and first pressed portion 5a
Is a block road surface 9 in the road surface anti-icing block 1.
They are formed symmetrically on the rear side and the front side in the traveling direction of the vehicle traveling above. In addition, the second pressed portion 4b
The second pressing portion 5b is formed in the road surface antifreezing block 1 at a symmetrical position orthogonal to the traveling direction of the vehicle traveling on the block road surface 9. The second pressed portion 4b and the second pressed portion 5b are formed on either the center side or the end side with respect to the traveling direction of the block road surface 9. Which one is to be formed is appropriately selected depending on the relationship with the other adjacent block 1, the block 1 on the center line, and the block 1 at the end.

In the road surface anti-icing block 1 of this embodiment, the pressing surfaces of the pressing portions 5a and 5b of the upper block 6 and the pressing surfaces of the pressed portions 4a and 4b have substantially the same shape. Has been formed. As a result, the gap between adjacent blocks 1 does not become too large, and the pressing force is efficiently transmitted from the pressing portions 5a and 5b to the pressed portions 4a and 4b. Further, it is not necessary to distinguish the arrangement position and the arrangement direction of the road surface anti-icing block 1 during the laying work, and the construction time can be shortened.

The lower block 2, the first upper block 4 and the second upper block 5 are preferably made of the same material and in the same shape in order to reduce the manufacturing cost.
As the material, it is preferable that the material has a weight that an automobile or the like passes through and a strength that can withstand impact, and concrete and synthetic resin can be mentioned. In the present embodiment, the second upper block 5 has a positional relationship in which it is slid in the horizontal direction with respect to the first upper block 4, and the pressing portions 5a and 5b and the pressed portions 4a and 4b prevent the road surface from freezing. The block 1 is formed at a position symmetrical with respect to the plane center point of the block 1.

The elastic member 3 is made of a material such as rubber which can be appropriately elastically deformed and restored with respect to the weight of the vehicle.
Of course, when it is used on a sidewalk or the like, it is required to undergo appropriate elastic deformation with respect to the weight of a pedestrian. Also,
Since the degree of elastic deformation and contraction also depends on the height of the elastic member 3, if the height of the elastic member 3 is too small, it is not possible to form a step enough to crush the frozen ice disk, and if it is too large. If it contracts extremely, it will hinder the running of vehicles and the walking of pedestrians. Therefore, the elastic member 3 of the present embodiment can contract at least to the extent that it crushes the frozen ice disk 10 on the block road surface 9, and it contracts extremely even when a large vehicle such as a truck or a snow plow rides on it and runs. It is formed to a height that does not interfere.

When the main block 1 is applied to a sidewalk exclusively for pedestrians and bicycles, the elastic member 3 is used.
For the rubber, rubber that can be appropriately elastically deformed and restored by the weight of the pedestrian may be appropriately selected. As a result, the ice board 10 can be appropriately crushed by the walking of the pedestrian, and even if the pedestrian falls, the cushioning effect can be appropriately exerted and the impact can be softened.

As shown in FIGS. 1 and 2, the upper edges of the first pressing portion 5a and the second pressing portion 5b of the second upper block 5 are chamfered, and the chamfered portion 8 is formed. . This is formed so that the vehicle traveling on the block road surface 9 can smoothly travel backward. That is, when there is a step at the destination, such as when backing up, the impact is great when it hits the edge of the road surface freeze prevention block 1, so the edge is removed in order to avoid the impact. The chamfered portion 8 is formed to have a large chamfer width if the step height generated between the adjacent road surface anti-icing blocks 1 is large, and is formed to be small if the step height is small. The chamfered portion 8 is not limited to a flat surface, and may have an arc shape.

Further, the road surface anti-icing block 1 is formed with a through hole 7 penetrating the lower block 2, the elastic member 3 and the upper block 6 in the height direction. Since rainwater and snowmelt water on the block road surface 9 flow into the through holes 7 and are guided downward, hydroplaning phenomenon on the block road surface 9 and refreezing of the snowmelt water are prevented. Further, the through hole 7 also serves as a relief that absorbs deformation when the elastic member 3 is vertically compressed. That is, if the through hole 7 is not formed in the elastic member 3, it will come out from the side surface when the elastic member 3 is compressed and deformed. However, since the through hole 7 is formed, the through hole 7 side It will pop out in and absorb the deformation. As a result, between the paved road surface antifreezing blocks 1, the adjacent road surface antifreezing blocks 1 can move up and down without being disturbed.

Next, an example of an embodiment of a block road surface 9 formed by using the road surface anti-icing block 1 of the present embodiment described above will be described with reference to the drawings.

FIG. 3 is a top view showing an embodiment of the block road surface 9 according to the present invention, and FIG. 4 (a) is an X in FIG.
FIG. 4B is a sectional view taken along line X-Y, and FIG. 4B is a sectional view taken along line Y-Y. Both show the road surface anti-icing block 1 laid at the outer end position of the block road surface 9. Further, FIG. 4C is a cross-sectional view taken along the line ZZ, showing the road surface freeze prevention block 1 in the width direction of the round trip road.
Is an array of.

The block road surface 9 shown in FIG. 3 is a general one-way one-lane round-trip road, so that the vehicle travels in the left and right opposite lanes 9A and 9B around the center line in the directions of the arrows in FIG. Has become. In FIG. 3, the broken line shows the first upper block 4 and the lower block 2, and the solid line shows the second upper block 5. Then, the road surface anti-icing block 1 has the pressing portions 5a, 5b and the pressed portions 4a, 4b according to the arrangement position on the road having one lane on one side.
Among them, the road surface anti-icing block 1 in which only one is formed and the road surface anti-icing block 1 in which both are formed are selected and laid.

For example, in this embodiment, as shown in FIG. 4, neither the first pressing portion 5a nor the first pressed portion 4a is formed in the vehicle traveling direction at the center line position of the road, The road surface antifreezing block 1 in which only the second pressed portion 4b is formed is arranged in a direction orthogonal to the traveling direction of the vehicle. That is, this center line block 10
Is formed to have a convex cross section, as shown in FIG.

At both ends in the width direction of the road, a first pressing portion 5a is formed on the front side in the vehicle traveling direction, and a first pressed portion 4a is formed on the rear side, and
A road surface anti-icing block 1 in which only the second pressing portion 5b is formed is arranged on the center line side in a direction orthogonal to the vehicle traveling direction.

A first pressing portion 5a is formed on the front side in the vehicle traveling direction, and a first pressed portion 4a is formed on the rear side at an intermediate position sandwiched between these two arrangement positions. Further, the road surface anti-freezing block 1 in which the second pressing portion 5b is formed on the center line side and the second pressed portion 4b is formed on the end side in the direction orthogonal to the vehicle traveling direction is arranged. .

As shown in FIGS. 3 and 4, in the block road surface 9 of the present embodiment, each road surface anti-icing block 1 has its pressing portions 5a and 5b of the adjacent road surface anti-freezing block 1. The pressed portions 4a and 4b are sequentially laid so as to overlap each other. For example, in FIG.
As shown in (b), the first pressed portion 4a of the road surface anti-icing block 1 is overlapped with and pressed by the first pressing portion 5a of the road surface anti-freezing block 1 that is adjacently arranged rearward in the traveling direction of the vehicle. It is supposed to be done. Further, as shown in FIG. 4C, the second pressed portion 4b is overlapped and pressed by the second pressed portion 5b of the road surface anti-icing block 1 which is adjacently arranged in the direction orthogonal to the vehicle traveling direction. It has become so. In the present embodiment, the second pressing portion 5b is laid so as to project toward the center line and the second pressed portion 4b is formed on the end side.

With the above combination, in the traveling direction of the vehicle and the direction orthogonal thereto, the adjacent road surface anti-icing blocks 1 do not sink together to cause a step, or only one of the road surface freeze preventing blocks does not cause a step. A block road surface 9 is formed which may occur.

After laying the road surface anti-icing blocks 1 as described above, in this embodiment, the gaps between the road surface anti-freezing blocks 1 are not filled in the joints but left as they are.
As a result, the road surface anti-icing blocks 1 are not fixed and easily move up and down. Furthermore, since rainwater, snowmelt water and the like on the block road surface 9 flow through the gaps, it is possible to prevent the hydroplaning phenomenon and refreezing of the snowmelt water on the block road surface 9.

Next, the function and effect of the block road surface 9 formed by using the road surface anti-icing block 1 according to the present invention will be described with reference to the drawings.

FIG. 5 is a sectional view for explaining the operation and effect when the vehicle 12 travels on the block road surface 9 according to the embodiment of the present invention. In the figure, arrows indicate the traveling direction of the vehicle, and reference numerals (a), (b), (c),
All of (d) indicate the road surface anti-icing block 1 according to the present invention.

First, as shown in FIG. 5A, the vehicle 12
When the vehicle rides on the road surface anti-freezing block (b) of the block road surface 9, the elastic member 3 elastically deforms and contracts according to its weight. With this deformation, the upper block 6 is lowered below the other upper blocks 6. At this time, the first pressing portion 5a of the road surface anti-freezing block (b) presses the first pressed portion 4a of the road surface anti-freezing block (c) that is adjacent to the front side in the traveling direction, so that the road surface anti-freezing block (h) ) Is also pushed down.

Due to these actions, there is no step between the road surface antifreezing blocks (b) and (c), which is located in front of the vehicle 12 in the traveling direction, so that the vehicle 12 can travel smoothly. In particular, even when the snow removing work vehicle removes snow on the block road surface 9, it is possible to prevent the road surface freezing prevention block 1 on the road surface from being scraped off by the snow removing plate, and smooth snow removing work can be performed. On the other hand, the vehicle 12
Since a step is formed between the road surface anti-icing blocks (a) and (b) which are behind the traveling direction of the road surface, this step facilitates crushing of an ice plate (not shown) frozen on the upper surface of the road surface anti-freezing block 1. .

Then, when the vehicle 12 further travels,
As shown in FIG. 5B, the vehicle 12 is in a state of riding on the road surface freeze prevention blocks (b) and (c) of the block road surface 9. In this case, the total weight of the vehicle 12 is distributed to both the road surface freeze prevention blocks (b) and (c). Therefore, regarding the road surface anti-icing block (b), the elastic member 3 is restored by the elastic force and the upper block 6
Return the height of the to slightly above.

On the other hand, regarding the road surface anti-icing block (c), the elastic member 3 contracts due to the weight of the vehicle 12, the upper block 6 sinks downward, and the first pressing portion 5a of the road surface anti-icing block (c) becomes By pressing the first pressed portion 4a of the road surface anti-icing block (d) adjacent to the front in the traveling direction, the same operation as described above works, and the road surface anti-icing block (d) is inclined rearward in the traveling direction. Becomes Thus, in the front of the traveling direction of the vehicle 12,
The first pressing portion 5 of the road surface anti-icing block 1 that is always on
Since a presses another adjacent first pressed portion 4a, a smooth block road surface 9 is formed.

On the other hand, when the vehicle 12 completely moves on the road surface antifreezing block (c), the road surface antifreezing block (b) is restored to its original height by the elastic force of the elastic member 3 and the road surface freezing block (b) is frozen. The prevention block (c) sinks and creates a step. The ice disk is crushed by such steps and impacts.

In FIG. 5 (a), when the elastic member 3 is made of a material having a high degree of contraction, when the vehicle 12 rides on the road surface anti-icing block (b),
Since the elastic member 3 contracts deeper, it also affects the road surface antifreezing block (d), and the road surface antifreezing block (d) also slightly advances via the first pressing portion 5a of the road surface antifreezing block (c). It will be in a state of inclining backward in the direction.
Therefore, the smooth block road surface 9 can be formed further forward.

On the other hand, as shown in FIG.
When the vehicle travels back on the block road surface 9 (travels in the direction opposite to the legal traveling direction), a step is formed in front of the traveling direction. However,
In the road surface anti-icing block 1 of this embodiment, the first
Since the chamfered portion 8 is formed on the upper edge of the pressing portion 5a, the tire of the vehicle 12 can smoothly pass over the step due to the chamfered portion 8 and smoothly travel back.

In the present embodiment, also in the direction orthogonal to the traveling direction of the vehicle 12, the second pressed portion 4b having the same effect as the first pressed portion 4a and the first pressed portion 5a described above. And the 2nd press part 5b is formed. The chamfered portion 8 is also formed on the upper edge of the second pressing portion 5b. As a result, even when the vehicle 12 travels in a direction different from the traveling direction defined on the block road surface 9 such as when the vehicle 12 changes its course, smooth travel can be achieved without feeling the impact due to the step. It will be possible.

Further, by forming the chamfered portion 8, a groove having a fine width is formed on the block road surface 9.
Therefore, when the vehicle 12 travels on this block road surface 9,
The tire receives a minute vibration from this groove. Therefore,
When this block road surface 9 is applied to a specific section where special attention must be paid to excessive speed, such as a curved slope or the like of a mountain pass, it is also effective as a road that calls attention to the driver. .

The road surface antifreezing block according to this embodiment and the block road surface using the same are not limited to those in the above-described embodiment, but can be modified as appropriate.

For example, in the above-described embodiment, as the road surface anti-icing block 1, blocks each having a shape as shown in FIG. 4C are selected and laid corresponding to predetermined arrangement positions on the block road surface 9. Therefore, there is no step in the forward direction in any of the lanes of the roundabout. However, as shown in FIG. 6, the road surface antifreezing block 1 in which only the second pressing portion 5b or the second pressed portion 4b is formed is arranged at both end positions in the width direction of the road, and both end positions thereof are arranged. At the intermediate position sandwiched by the second pressing portion 5b in the direction orthogonal to the vehicle traveling direction.
Alternatively, the road surface anti-icing block 1 on which both the second pressed portion 4b are formed may be arranged.

Further, as shown in FIG. 7, a road surface anti-icing block 1 having two second pressing portions 5b formed in a direction orthogonal to the vehicle traveling direction is arranged at the center line position of the road, The road surface antifreezing block 1 having the second pressed portion 4b formed on the center line side in a direction orthogonal to the vehicle traveling direction is arranged at both end positions in the width direction of the vehicle, and is sandwiched between the both arrangement positions.
