Abstract

PROBLEM TO BE SOLVED: To improve slip resistance in anti-slip pavement.SOLUTION: An aggregate layer is formed on pavement 10 such as asphalt and concrete by fixing an aggregate 14 with a binder 11. The aggregate 14 is obtained by mixing approximately 30% crushed aggregate into an aggregate made of a so-called flash aggregate. A top coat 15 is applied onto the aggregate 14. In the top coat 15, a filler 16 comprising an aggregate powder having a particle size of 0.15 mm or less is added approximately 30 wt.% based on the top coat. As a result, slide resistance can be improved by an effect of the filler 16 while suppressing the scattering of the aggregate 14. The slide resistance can be further improved by mixing the crushed aggregate.

Description

  The present invention relates to a non-slip pavement in which an aggregate is dispersed on a pavement surface such as asphalt or concrete using a resin binder and fixed to a road surface, and more particularly to a non-slip pavement in which a top coat is applied.

Conventionally, the non-slip pavement is also called a neat method, and is widely used for the purpose of improving the visibility of the road surface or improving the slip resistance.
FIG. 1 is an explanatory view showing an application example of slip prevention pavement. A region A in FIG. 1A is a lane dedicated to a bus, and a non-slip pavement using colored aggregate is applied to this portion. FIG. 1B schematically shows the road surface structure. In the portion where the slip prevention pavement is applied, the aggregate 12 is dispersed and fixed on the pavement surface 10 using a resin binder 11. Further, a top coat 13 made of resin may be applied on the aggregate 12. The area a in FIG. 1B shows the road surface structure without the top coat, and the area b shows the road surface structure with the top coat 13. On the right side of FIG. 1 (b), an enlarged view of a portion to which the top coat 13 has been applied is shown.
By using a colored aggregate 12, the color of the road surface can be finished to a color different from that of paved surfaces such as asphalt and concrete, and visually indicate that the lane is for buses. It becomes possible. In addition, slip resistance pavement has higher slip resistance than a normal pavement surface, so that it is also applied to a part requiring an antiskid effect such as a curve or a slope in addition to the above-described visual use.
As a prior art of the pavement method for spraying the aggregate as described above, Patent Document 1 discloses a pavement method for spraying stone powder, hard aggregate, and the like immediately after asphalt pavement. Patent Document 2 discloses a pavement method in which a fast-curing resin is spray-coated and aggregates are dispersed at the same time.

Japanese Patent No. 3179717 Japanese Patent No. 4054124

In the non-slip pavement, the use of a top coat can suppress the scattering of the aggregate and enhance the durability. However, when the top coat is applied, the slip resistance tends to be lower than when the top coat is not provided.
In view of such problems, the present invention has an object of improving the slip resistance when a top coat is applied in a non-slip pavement.

Non-slip paving method in the present invention,
a) applying a resin binder on the pavement surface, spreading the aggregate, and fixing the aggregate to the pavement surface;
b) A step of applying a top coat with a resin by mixing an additive aggregate having a particle size smaller than that of the aggregate on the aggregate on the pavement surface.

  According to the non-slip pavement method of the present invention, the slip resistance can be improved by mixing the aggregate with the top coat. Therefore, it is possible to achieve both suppression of aggregate scattering by the top coat and maintenance / improvement of slip resistance.

The pavement surface of the present invention may be either asphalt or concrete.
As the resin-based binder, various resins that can hold an aggregate, such as a well-known material conventionally used in non-slip pavement, such as a flexible epoxy resin, can be used.
Similarly, various materials such as black hard aggregates, colored porcelain aggregates, and silicon carbide aggregates conventionally used in non-slip pavements can be used as the aggregates. The particle size is about 0.5 mm to 3.5 mm, and can be arbitrarily selected according to the material and purpose. In general, a particle having a particle diameter of 0.5 to 1.0 mm is referred to as a B particle, a particle having a particle diameter of 1.0 to 2.0 mm is referred to as an A particle, and a particle having a particle diameter of 2.0 to 3.3 mm is referred to as an A1 particle.
As a method of mixing the added aggregate in the top coat, either a method of applying a resin for top coat to which the added aggregate has been added in advance or a method of spraying the added aggregate after applying the top coat may be taken. .

In the slip prevention pavement method of the present invention,
The aggregate on the pavement surface may include a crushed aggregate formed by crushing an aggregate lump so as to have a predetermined particle size.
In general, aggregates are roughly classified into two types according to the production method. One is a so-called “barakiki aggregate”, which is manufactured by firing it after it has been formed to a predetermined particle size in advance, and the other is fired as a large brick-like lump. It is called a crushed aggregate formed by crushing a lump until it has a fine particle size. The crushed aggregate is characterized by a sharper corner than the burakaki aggregate. Therefore, as shown in the above method, the slip resistance can be further improved by blending the crushed aggregate with the aggregate on the pavement surface.
From the viewpoint of slip resistance, the larger the amount of crushed aggregate, the better. However, in general, crushed aggregate often generates finer particles than the intended particle size when crushing a lump, and the yield during formation is usually worse than that of Balikaki aggregate. Manufacturing costs tend to be higher than Balikaki aggregate. Considering both improvement of slip resistance and cost reduction, the blended amount of the crushed aggregate is preferably about 30% by weight of the whole.
The crushed aggregate and other aggregates may have the same or different particle sizes. In order to easily exhibit the anti-slip effect due to the shape of the crushed aggregate, it is preferable that the particle size of the crushed aggregate is equal to or greater than the particle size of the other aggregates.

In the present invention, as a method of mixing the additive aggregate in the top coat, it can also take a method of spraying the additive aggregate after the top coat is applied,
The step b) preferably includes a step of adding the added aggregate to the resin in advance and a step of applying the added resin and applying the top coat.
By doing so, there is an advantage that the added aggregate can be mixed evenly in the top coat. In addition, since it is possible to reduce the step of spraying the added aggregate after applying the top coat, it is preferable in terms of simplification and ease of the process.

In the method of adding added aggregate to the top coat in advance,
The particle size of the added aggregate is preferably 0.15 mm or less.
By making the particle size of the added aggregate very fine as described above, there is an advantage that the added aggregate added to the top coat can be prevented from easily settling. As a result, the top coat can be applied in a state where the additive aggregate is uniformly mixed in the top coat, and the anti-slip effect can be exhibited uniformly.

In the slip prevention pavement method of the present invention,
The top coat may be applied with MMA resin.
The MMA resin is an acrylic resin. Various resins can be used as the material of the top coat. By using an MMA-based resin, scattering of the aggregate can be suppressed and durability can be enhanced.

The present invention can be configured as a non-slip pavement method or a non-slip pavement structure paved by the method.
That is, by applying a resin binder on the pavement surface, spraying the aggregate, and an aggregate layer in which the aggregate is fixed to the pavement surface;
An anti-skid pavement structure comprising a top coat layer in which an additive aggregate having a particle size smaller than that of the aggregate is mixed and a resin is applied on the aggregate layer.
By providing the top coat layer having such a structure, it is possible to improve the slip resistance while suppressing the scattering of the aggregate.

Various characteristics shown in the pavement method can be applied to the non-slip pavement structure.
For example, the aggregate of the aggregate layer may include a crushed aggregate formed by crushing an aggregate lump so as to have a predetermined particle size.
Further, the top coat layer may be formed in a state where the added aggregate is substantially uniformly distributed. Such a structure can be formed, for example, by applying a top coat in a state in which an additive aggregate is added in advance to a resin for the top coat.
In this case, the particle size of the added aggregate is preferably 0.15 mm or less.
Furthermore, the topcoat layer may be formed of an MMA resin.

  The various features described above for the present invention are not necessarily all provided, and may be applied by omitting some or combining them appropriately.

The slip prevention pavement method as an embodiment of the present invention will be described in the following order.
A. Non-slip pavement structure:
B. Non-slip paving process:
C. Effect by blending amount etc .:
C1. Effect of filler particle size:
C2. Effect of added amount of filler:
C3. Effect by the ratio of crushed aggregate:
C4. Effect of filler addition and crushed aggregate composition:
D. Effects and variations:

In the following description, the relationship between the names of the A grains and the particle diameter is as follows.
A1 grain 3.3-2.0mm
A grain 1.0-2.0mm
B grain 0.5-1.0mm
C grain 0.15-0.5mm
F grain 0.15mm or less

A. Non-slip pavement structure:
FIG. 1 is an explanatory view showing an application example of slip prevention pavement. Non-slip pavement is mainly applied to a portion of the road surface that is desired to be visually distinguished, such as a region A in the figure, or a portion that is desired to increase slip resistance, such as a curved portion.
The anti-slip pavement structure in the prior art has a structure in which an aggregate 12 is fixed on a pavement surface 10 by a binder 11 as shown in FIG. A top coat 13 may be applied on the aggregate 12 (region b).
On the other hand, the anti-skid pavement structure of the present Example was shown in FIG.1 (c). In the non-slip pavement structure of the embodiment, the binder 11 is applied on the pavement surface 10, and the aggregate 14 is dispersed and fixed. In this example, as the aggregate 14, a mixture of crushed aggregate and variegated aggregate was used. As the aggregate, A1 grain to B grain are used. As a material of the aggregate, a colored porcelain aggregate, a black hard spinel aggregate, or the like can be used. As the aggregate, it is preferable to use a material excellent in wear resistance.
In this specification, the layer which spread | dispersed the aggregate on a pavement surface is called an aggregate layer.

In general, aggregates are roughly classified into two types according to the production method. One is a so-called “barakiki aggregate”, which is manufactured by firing it after it has been formed to a predetermined particle size in advance, and the other is fired as a large brick-like lump. It is called a crushed aggregate formed by crushing a lump until it has a fine particle size. In this embodiment, the crushed aggregate is blended and spread on the pavement surface 10. Since the crushed aggregate has a feature with a sharper corner than the burakaki aggregate, by using the crushed aggregate, it is possible to improve the slip resistance of the pavement surface.
The blending amount of the crushed aggregate can be arbitrarily set in consideration of the target value of slip resistance, cost, and the like. The effect of the blended amount of the crushed aggregate on the slip resistance will be described later.

A top coat 15 is applied to the surface of the aggregate 14. In the embodiment, as shown on the right side of FIG. 1C, a fine powder of aggregate called filler 16 is mixed in the top coat 15. As the filler 16, for example, fine powder inevitably generated at the time of manufacturing the crushed aggregate can be used. You may use the filler of a different material from the aggregate spread on a road surface. The particle size and blending amount of the filler 16 can be set arbitrarily, but the effect on the slip resistance will be described later. In the present specification, the layer provided with the top coat 15 is referred to as a top coat layer.
Thus, according to the non-slip pavement structure of the present embodiment, the top coat 15 can be applied to suppress the scattering of the aggregate 14 and improve the durability. By mixing 16, it is possible to improve the slip resistance. Furthermore, slip resistance can be further improved by blending the aggregate 14 with the crushed aggregate.

B. Non-slip paving process:
Next, the process of applying anti-slip pavement will be described.
FIG. 2 is a flowchart showing a non-slip paving process. Here, on the existing asphalt or concrete pavement surface, a resin binder is applied, an aggregate is spread, and a top coat is applied. ) Was completed. These processes are performed manually or using a machine.
Moreover, FIG. 3 is explanatory drawing which shows the mode of non-slip pavement. Hereinafter, the steps will be sequentially described with reference to FIG. 2 while referring to FIG. 3 as appropriate.

First, the worker performs surveying and marking of the portion to be surface-treated (step S10). Then, masking of necessary portions is performed (step S11). Examples of locations for masking include road markings, manholes, water / gas taps, guardrails, curbs, and the like.
When the masking is completed, in the case of a concrete pavement surface, a primer is applied by a roller or air spray (step S12). In the case of an asphalt pavement surface, this step can be omitted.
The worker applies a resin binder for fixing the aggregate (step S13). It is desirable to apply the resin-based binder to a uniform film thickness using a coating machine. The film thickness of the resin binder is preferably such that 1/2 to 1/3 of the aggregate is buried.
Next, the worker sprays the aggregate (step S14). As described above, in the present embodiment, as the aggregate, a mixture of Balikaki aggregate and crushed aggregate is sprayed. Each may be sprayed individually, or may be sprayed after blending in advance. In order to spread uniformly, it is more preferable to mix in advance. Since the adhesive strength of the aggregate decreases with time after the application of the resin binder, the aggregate is sprayed as soon as possible after the application of the resin binder. The amount of aggregate spread is approximately 4.0 to 8 kg per square meter. Aggregate that is not sufficiently fixed and scatters is inevitably generated, and therefore, it is preferable that the aggregate is slightly dispersed.
When the dispersion of the aggregate is finished, the masking is removed before the resin binder is cured (step S15).
Then, it waits for curing, that is, until the resin binder is sufficiently cured (step S16). The curing time of the resin binder varies depending on the road surface temperature and the like. If the passage is started in a state where the curing is insufficient, there is a problem that the aggregate falls off or is buried in the resin binder. Therefore, it is necessary to sufficiently confirm the cured state at a plurality of locations.
When curing is completed, the worker collects surplus aggregate that has not been sufficiently fixed with the resin binder (step S17).
The above is the process of spreading the aggregate on the paved surface and forming the aggregate layer.

Next, the process for forming the topcoat layer is entered.
The worker first performs masking before the top coat (step S18). The masking target is the same as in step S11.
When the masking is completed, the worker applies a top coat to which a filler is added (step S19). In this example, the filler was added to the topcoat resin in advance and stirred, and then applied. Accordingly, the step of adding the filler to the top coat resin is performed in parallel with the masking (step S18) or just before the application (step S19).
FIG. 3A shows a situation where a filler is added to the topcoat resin 15 </ b> A and stirred by the stirrer 20. The addition of the filler is one of the features in the process of the present embodiment that it is a simple process that can be performed manually without using a dedicated machine.
FIG. 3B shows the state of top coat application. Since the top coat to which the filler has been added tends to be clogged when it is applied by airless spraying, it is preferably performed by the roller 21 so as to have a uniform thickness as in the case of applying the binder. The amount of top coat applied varies depending on the particle size of the aggregate. When using MMA resin system, it is preferable to set it as 0.4-0.8 kg per square meter.
After applying the top coat, it is fully cured (step S20 in FIG. 2), the masking is removed (step S21), and the process is completed.

  FIG. 3C shows the state of the paved surface after construction. The granular material recognized in the photograph is the aggregate 14. Since the filler contained in the top coat is a very fine powder, it cannot be visually recognized unless further enlarged.

  As described above, the slip-proof paving process of the present embodiment is almost the same as the conventional one. What is different from the prior art is that in the dispersion of the aggregate (step S14), a state where the burakaki aggregate and the crushed aggregate are mixed and a top coat to which a filler is added is applied. These two steps can be performed without requiring a dedicated machine as compared with the conventional steps. In this sense, the pavement according to the present embodiment can be said to be a pavement method that can be applied relatively easily. .

C. Effect by blending amount etc .:
Below, in the slip prevention pavement of a present Example, the effect by the compounding quantity of a crushed aggregate, the addition amount of a filler, etc. is demonstrated.
The effect was evaluated using a BPN value generally applied in the road industry as a slip resistance value. The BPN value is a result measured by a portable skid resistance tester (hereinafter referred to as “measuring instrument”) developed by the Road Traffic Research Institute in the UK. The experiment for measuring the BPN value was performed in a wet state where water was sprayed on the pavement surface, and after performing the measurement four times, the BPN value was obtained by arithmetically averaging the three measurement values excluding the first. Moreover, the temperature correction by the following formula generally used in the road industry was applied to the result thus obtained, and the BPN value when the temperature was 20 ° C. was obtained.
C20 = −0.0071t ^ 2 + 0.9301t-15.79 + Ct;
Here, each variable has the following meaning.
C20 ... BPN corrected to 20 ° C
Ct: BPN before correction
t ... Surface temperature at the time of measurement ^ ... Operator representing square

C1. Effect of filler particle size:
In this example, a filler is added in advance to the top coat resin, and the top coat is applied with stirring (see FIG. 3A). When the particle size of the filler to be added was decreased in the order of B particles, C particles, and F particles, the following results were obtained.
When the B-grain filler was added, the filler settled in several seconds to several tens of seconds after the addition regardless of the addition amount, and could not be applied as a top coat.
When the filler of C grains was added, sedimentation occurred although it was slower than the B grains. When the amount of filler added was 20% or less, it could be applied as a top coat. However, even in this case, sedimentation occurred in the topcoat after coating, and the effect of adding the filler was not fully exhibited.
In the case of the F-grain filler, no significant sedimentation occurred until the topcoat resin was cured, and the topcoat could be satisfactorily applied.
Therefore, it can be said that a smaller particle size of the filler is desirable, and it can be said that it is more preferable to use F particles.

C2. Effect of added amount of filler:
FIG. 4 is an explanatory diagram showing the effect of the filler addition amount. It is the experimental result which measured the improvement rate of BPN at the time of changing the addition amount of the filler of F grain | grains by weight 10% with respect to a topcoat every 0% to 40%. FIG. 4A shows a list of experimental results, and FIG. 4B shows a graph of the BPN improvement rate after temperature correction. The improvement rate is a change rate of BPN based on the state without filler.
As shown in the figure, it can be seen that when the amount of filler added is increased, the BPN is improved accordingly. In this experiment, in a state where 30% of the filler was added, the result was obtained that the BPN was improved by 106.4% as compared with the case without the filler.
If the filler addition amount is more than 30%, it is considered that BPN is further improved. However, if the addition amount is 40%, it is difficult to apply the filler, which is different from the improvement of BPN in that the finish is not uniform. It turns out that a problem arises.
Therefore, when F grains are used, it can be said that the amount of filler added is preferably about 30% by weight with respect to the top coat.

C3. Effect by the ratio of crushed aggregate:
FIG. 5 is an explanatory view showing the effect of the crushed aggregate compounding ratio. It is the experimental result which measured the improvement rate of BPN at the time of changing the compounding rate of a crushing aggregate and a burakaki aggregate. FIG. 5A shows a list of results when no filler is added to the top coat, and FIG. 5B shows a list of results when 30% of the filler is added to the top coat. . The improvement rate is a change rate of BPN in each case with reference to a state in which there is no crushed aggregate (100% of burakaki aggregate).
FIG. 5C is a graph showing the BPN improvement rate after temperature correction. The results indicated by ◯ and broken lines indicate the case where no filler is added (corresponding to FIG. 5A), and the results indicated by ● and solid lines indicate the case where 30% of filler is added (FIG. 5 ( corresponding to b)).
As shown in the figure, it can be seen that, in any case where the filler is added or not, if the blending ratio of the crushed aggregate is increased, the BPN is improved accordingly. In this experiment, in the state where 50% of the crushed aggregate was added, the result of 117.4% improvement in the case where the filler was not added and 114.5% improvement in the case where the filler was added 30% was obtained. In the case where 30% of filler is added, the BPN improvement rate when crushing aggregate is 100% is not measured, but as with the case where filler is not added, BPN is monotonous as the blending ratio of crushing aggregate increases. It is estimated that it will improve.
From the viewpoint of slip resistance alone, it can be said that the higher the blending ratio of the crushed aggregate, the better. However, since crushed aggregate is generally more expensive than burakaki aggregate, it is preferable to suppress the blending ratio of crushed aggregate in terms of cost. Therefore, the blending ratio of the crushed aggregate is preferably set to the minimum value within a range that satisfies the target value of the slip resistance. From this point of view, for example, the blending ratio can be about 30%.

C4. Effect of filler addition and crushed aggregate composition:
FIG. 6 is an explanatory view showing the effect of filler addition and crushing aggregate composition. It is the experimental result which measured the improvement rate of BPN as an effect at the time of applying 30% addition of a filler, 30% mixing | blending of a crushing aggregate separately, and applying it in combination. The experiment was conducted over 2 days. FIG. 6A shows a list of experimental results on the first day, and FIG. 6B shows a list of experimental results on the second day. The improvement rate is a change rate of BPN in each case with reference to the state of no filler addition and no crushed aggregate (100% burakaki aggregate).
FIG. 6C is a graph showing the BPN improvement rate after temperature correction. The numbers i to vi in the graph represent the corresponding relationship with the experimental results of FIGS. 6A and 6B, respectively.
As shown in the figure, when 30% of the crushed aggregate is added without adding a filler (i, iv), it can be seen that a BPN improvement rate of 110.9 to 112.9% is obtained. This is the single effect of the crushed aggregate composition.
It can be seen that when 30% filler is added without crushed aggregate (ii, v), a BPN improvement rate of 106.4 to 106.8% is obtained. This is the single effect of the filler addition.
When 30% of filler is added and 30% of crushed aggregate is added (iii, vi), it can be seen that a BPN improvement rate of 118.0 to 119.3% is obtained. This is the effect of the combination of filler addition and crushed aggregate composition. In general, it can be seen that the effect of adding a single improvement rate when the filler addition and the crushed aggregate composition are individually applied is obtained.

D. Effects and variations:
According to the slip prevention pavement method and the structure of the present embodiment described above, the slip resistance can be improved by adding a filler. Therefore, it becomes possible to achieve both improvement in durability of the paved surface by the top coat and maintenance / improvement of slip resistance.
Moreover, slip resistance can be further improved by blending the crushed aggregate.

In the present embodiment, the step of adding the filler to the topcoat resin in advance and stirring and applying the topcoat was shown, but the method of mixing the filler in the topcoat is not limited to this method, and will be described below. As described above, the modified method may be used.
FIG. 7 is a flowchart showing a non-slip pavement process as a modified example. FIG. 7A shows only the step of forming the topcoat layer after the masking before the topcoat (step S18) among the steps shown in FIG.
In the process of the modified example, after the aggregate layer is formed, masking before the top coat is performed (step S18) and the top coat is applied (step S19A) as in the case of the embodiment (FIG. 2). However, in the example (FIG. 2), the top coat to which the filler was added was used, but here the top coat is applied without adding the filler.
Then, a filler is sprayed on the top coat (step S19B). Then, curing is performed (step S20), and masking is removed (step S21). Furthermore, excess filler that has not been fixed on the top coat is recovered (step S21A), and the process is terminated.
Thus, the top coat layer mixed with the filler can be formed also by the method of spraying the filler after the top coat is applied, and the effect of improving the slip resistance can be obtained.

FIG. 7B shows the experimental results regarding the effects of the modified method. When the fillers to be spread were B, C and F, respectively, the BPN improvement rate based on the state without filler was shown.
As shown in the figure, after the temperature correction, a BPN improvement rate of 109.2% is obtained when the B grains are dispersed, and 119.8% when the C grains are used. Thus, according to the method of the modified example, there is an advantage that B grains and C grains that could not be used in the examples can be applied to the topcoat layer. However, when F grains were used, they were so fine that they were scattered during spraying, resulting in inability to spray uniformly. It is thought that these problems can be overcome by applying a cover to prevent scattering.

  The present invention need not include all of the various features described in the above embodiments and modifications. Some of them may be omitted, or a combination can be applied as appropriate.

  INDUSTRIAL APPLICABILITY The present invention can be used for improving slip resistance value in anti-slip pavement.
