Description

Paving Method For High Elasticity Road

The present invention is to install a mixture of urethane, waste tire chips, silica sand powder, etc. in the upper part of the base layer to form an elastic layer and to mix the elastic needle such as urethane, urethane chips or urethane coated waste tire chips The elastic panel is formed by molding and pressing a mixture, or urethane chips or urethane-coated waste tire chips and silica sand are mixed, and a vinyl is applied to the upper layer to press the roller. It relates to a high-elastic road paving method, characterized in that.

The elastic packaging method is divided into two methods, a method of packaging using an elastic panel and a method of directly installing an elastic package in the field. The packaging method using the elastic panel is a method of forming the base layer and the elastic layer in advance, and installing and packaging the elastic panel manufactured by using a urethane chip or crushed waste tire chip on the top. On the other hand, the direct elastic packaging in the field is a method of packaging by packaging a mixture using a urethane chip or a waste tire chip on the base layer.

Conventional elastic packaging has been used a lot of elastic materials mixed with urethane chips and urethane. This method has been applied to a lot of track tracks for sports grounds, but the cost of urethane chips is high, and this method has a problem of high construction cost. In order to overcome this problem, a method of using waste tire chips that have been pulverized instead of urethane chips has been proposed. This method is a packaging method in which crushed waste tire chips are mixed with urethane and the mixture is laid on top of the base layer. However, the elastic pavement paved by this paving method has a problem in that the durability of the urethane and the waste tire is weakened by ultraviolet rays when exposed to sunlight for a long time.

On the other hand, the field installation type elastic packaging method is to install the elastic material mixed with urethane and urethane chip and wrap the upper part with a trowel or compaction with a roller, the conventional method is that urethane, etc. do not stick to the trowel or roller. In order to prevent this, the surface of the trowel had to be cleaned with a thinner, or the trowel or roller had to be heated. However, this conventional method requires a lot of thinner, so that the urethane in the surface layer is dissolved in the thinner and flows down to the lower layer, resulting in a weak strength of the surface layer, and a problem that the quality of the urethane remaining in the surface layer is not uniform, resulting in inconsistent quality. do. In addition, even when the surface is cleaned by heating a trowel or a roller, urethane melts in heat and flows down to the lower layer, which also lowers the surface strength.

On the other hand, the conventional panel installation method or site installation method all have to go through a long time curing process, there is a problem that if the rain or snow falls during construction, stop the construction or re-construction. In particular, the curing period is about 7 days, so if you choose a date that does not rain or snow during these periods, there is a problem that the period that can be constructed in one year is limited to a very limited.

The present invention is to solve the problems of the prior art, it is possible to replace all or part of the expensive urethane chips with urethane-coated waste tire chips to reduce the cost of construction and at the same time to recycle the waste materials It is done.

Another object of the present invention is a packaging method for installing an elastic panel, by installing an elastic layer in which waste tire chips and urethane are mixed on an upper portion of the base layer, and then providing an elastic panel on the upper portion thereof, immediately without curing period. It is to achieve the pavement of high elastic concrete which can be opened.

Another object of the present invention is to reduce the surface layer strength generated in the conventional field installation method by allowing the surface installation and compaction in the field installation method, without using a thinner and without heating the trowel or roller. To solve the problem.

The present invention is in common that the urethane-coated pulverized waste tire chip can be replaced all or part of the expensive urethane chip, the elastic panel installation packaging method and field installation packaging method by the construction method It can be divided into. Hereinafter, the elastic panel installation type packaging method will be described first, followed by the field installation type packaging method.

The elastic panel installation paving method of the present invention comprises the steps of pavement and curing the base concrete in a conventional manner to form a base layer or to wash the existing concrete pavement upper surface to form a base layer; Drying the surface of the base layer formed in the electrical process and then spraying any one of an epoxy primer and a urethane primer; Forming a elastic layer by drying a primer sprayed in the above-mentioned process, and then mixing a mixture of 0.05 to 0.3 parts by weight of urethane or epoxy with respect to 1 part by weight of pulverized waste tire chips of 10 mm or less on the top thereof; And forming an elastic panel formed by molding and pressing a mixture of urethane chips or urethane-coated waste tire chips on the elastic layer of the electrical process and mixing 0.05 to 0.3 parts by weight of urethane. .

The process of the elastic panel mounting type packaging method of this invention is demonstrated.

1st step: A process of forming a base layer by laying and curing base concrete in a conventional manner or forming a base layer by washing an upper surface of an existing concrete pavement.

This step is a step of forming the base layer as a premise for paving the high-elastic road of the present invention. The high-elastic road paving method of the present invention can be applied not only to newly laid roads, but also to the upper surface of existing concrete pavement.

In the case of forming a base layer by laying concrete or asphalt concrete for the foundation in the filter layer and the crusher layer by the conventional method, the concrete and the joint are installed after the concrete is laid. In the case of using the existing package, the surface of the package is washed with water to completely remove foreign substances. In case of permeability, permeability should be secured by using a suction cleaning method or a high pressure lake in order to reduce permeability voids. In addition, in the case of using the existing sidewalk block it is preferable to remove the foreign material on the surface of the sidewalk block using a spray or blower, and cut down the paving section to lower the pavement surface. On the other hand, in applying the method of the present invention, since the elastic panel forming the surface layer of the road is permeable (to be porous), when laying the road as a whole permeable, the base layer of the lower part may be laid permeable. .

Second step: A step of spraying any one of an epoxy primer and a urethane primer after drying the surface of the base layer formed in the electrical process.

This process is to apply an epoxy primer or a urethane primer to the upper surface of the base layer as a binder in order to firmly bond the elastic layer to be laid in the next step and the underlying base layer. Epoxy primer or urethane primer should be sprayed after the upper surface of the base layer is dried, the spray amount is preferably 0.2 ~ 2kg / ㎡. However, when the base layer is made of a permeable concrete layer (a large number of surface voids are formed), the urethane of the elastic layer to be installed on the upper side can penetrate into the voids so that the two layers can be firmly bonded. May be omitted.

The third step: After drying the primer sprayed in the electrical process, a mixture of 0.05 to 0.3 parts by weight of urethane or epoxy is added to 1 part by weight of the waste tire chip having a diameter of 10 mm or less on the upper portion thereof, and then the elastic layer is formed. Forming process.

This process is a preliminary step for installing the elastic panel. The waste tire chip is mixed with urethane to be laid, thereby utilizing the elasticity of the waste tire chip and adjusting the surface height of the pavement to make the elastic panel installed at the top flat. It is to be able to install stably. The waste tire chips and urethane are mixed with each other when exposed to sunlight, and their bonding strength is lowered due to the effect of ultraviolet rays, resulting in poor durability.However, the elastic layer installed in this process is covered by the upper elastic panel and is not exposed to sunlight. There is no problem. On the other hand, when it is necessary to increase the thickness of the adhesive cross section of the elastic layer in order to increase the durability and adhesive force, cement, silica sand, limestone, or lime powder of 50 mesh or less may be mixed and used within the range of 3 parts by weight. In order to enhance the strength, 3 parts by weight or less of silica sand having a diameter of 5 mm or less may be mixed and used. Of course, it is also possible to use a urethane chip in place of the crushed waste tire chip. However, since the price of the urethane chip is much higher than the price of the crushed waste tire chip and there is no significant difference in effect, there is little reason to use the urethane chip.

4th step: The process of installing the elastic panel which shape | molded and pressurized the mixture which mixed urethane chip or 0.05-0.3 weight part of urethanes with 1 weight part of urethane chips or the waste tire chip coated with urethane on the elastic layer of an electrical process.

This process is to install the elastic panel on the upper part of the elastic layer installed in the electrical process, the elastic panel to be installed at this time is convenient to manufacture and transfer to the construction site after use. Therefore, the elastic panel used in the present invention may be prepared in advance before construction. When the elastic panel is installed in this process, the upper part can be compacted with a roller so that the elastic panel is firmly placed on the lower elastic layer and can be opened immediately after opening. In addition, in order to increase the surface strength of the elastic panel, it is possible to spray a top coat of transparent urethane or transparent epoxy with a hardness of 70 or more on the surface of the elastic panel. It may be made in advance when manufacturing.

The method of manufacturing the elastic panel used in the present invention is as follows.

0.05 to 0.3 parts by weight of urethane was mixed with 1 part by weight of a urethane chip having a diameter of 10 mm or less and urethane-coated pulverized waste tire chips, and then the mixture was put into a mold having a suitable size, which was pressurized from the top to form a panel. After curing for a certain time to complete the panel. At this time, in order to manufacture the urethane-coated pulverized waste tire chip, the pulverized waste tire chip is first heated to 50-150 ° C. so that the surface of the waste tire chip is gelled, and then urethane is added and mixed. When urethane is introduced while the pulverized waste tire chips are not gelled, the urethane and the waste tire chips are easily separated when the coated force is weak and exposed to strong ultraviolet rays of sunlight.

In the production of the elastic panel, the urethane chip and the pulverized waste tire chip coated with urethane may be mixed and used at a predetermined ratio. The use of urethane chips is superior in elasticity and durability compared to the use of pulverized waste tire chips coated with urethane. However, due to the high cost of urethane chips, in consideration of the location of the construction site, urethane chips and urethane-coated crushed waste tire chips may be mixed at an appropriate ratio, or instead of urethane chips, the entire amount of crushed waste tire chips may be coated with urethane. Can also be used as

This elastic panel can also be manufactured and used in a roll shape. In the case of manufacturing in a roll shape, as shown in FIG. 3, a mixture of urethane chips or a urethane-coated crushed waste tire chip and a mixture of urethane is introduced into a mold placed on a belt conveyor through a hopper, and using a heating roller. After pressurizing, curing is carried out for a predetermined time. The roll-type elastic panel produced in this way may be wound and rolled up to be used for long stretches, or may be cut to an appropriate size.

In order to increase the durability and adhesiveness of the elastic panel, 1 part by weight of the urethane chip or the urethane-coated pulverized waste tire chip and 0.05 to 0.2 parts by weight of urethane or epoxy is one of cement, silica sand, limestone, and lime powder. Alternatively, the elastic panel may be manufactured by mixing two or more parts by 2 parts by weight or less. Further, in order to enhance the strength of the elastic panel, it may be added and mixed to 3 parts by weight or less of silica sand, sand and stone powder of 5 mm or less.

In addition, in the case of using a urethane chip of various colors, it is preferable to use a transparent urethane or an epoxy. In the case of using a colorless urethane chip or a non-uniform color urethane chip, it is aesthetically good to use a pigment. In this case, the pigment is preferably used within 0.2 parts by weight using an inorganic pigment.

In particular, in order to make the elastic panel of this invention firmly adhere | attach with an elastic layer, it is preferable to make the porosity of an elastic panel into 5-20%. Porosity can be controlled by the size and use ratio of silica sand, sand, stone powder, etc. to be added and mixed. This is because when the top of the elastic panel is compacted with a roller after the elastic panel is installed, particles of the elastic layer penetrate into the gaps of the elastic panel, and the elastic layer and the elastic panel are firmly in close contact with each other. In this case, the porosity of the elastic panel is set to 5 to 20% because the adhesion strength is lowered at 5% or less, and the strength of the elastic panel is lowered at 20% or more.

In addition, in forming the elastic panel of the present invention, the surface formed at the bottom of the mold is smooth surface and small voids, while the surface formed at the top of the mold is rough surface and large pores are formed. This is because urethane, epoxy, and the residual particles are molded in a state of flowing down. Therefore, in installing this elastic panel on the upper part of the elastic layer, it is preferable that the surface having a large void and the rough surface of the elastic layer is in contact with the elastic layer, that is, the surface having a small void and the smooth surface is the upper surface (surface layer). Do. The reason for this is that the particles of the elastic layer are easily permeated into the voids by contacting the elastic layer with the large voids and the rough portions, and the aesthetics become beautiful because the smooth, small voids become the upper surface (surface layer).

On the other hand, by applying the method of manufacturing the elastic panel of the present invention to the permeable block can also be produced a high elastic permeable block. In other words, cement is added to 1㎥ of aggregate of 1 granule with 90 ~ 100% passing through 13mm sieve, 0 ~ 40% passing through 2.0mm sieve, 0 ~ 20% passing through 1.0mm sieve, and 0 ~ 10% passing through 0.5mm sieve. 200 ~ 500㎏, water 50 ~ 200㎏ (water / cement ratio 25-40%), admixture 5kg or less (cement ratio of KS F 2560 1% or less) are mixed and put into the mold and molded by pressing, curing and A water permeable block is produced by steam curing, etc., and the elastic panel of the present invention having a predetermined thickness is bonded thereto.

In the method for producing a highly elastic water permeable block according to the present invention, a urethane chip or a urethane-coated ground waste tire chip is mixed with 1 part by weight of 0.05 to 0.5 parts by weight of urethane or epoxy, and cement or silica sand is 50 mesh or less. At least 2 parts by weight of one or more of limestone, lime powder, and at least 3 parts by weight of silica sand, sand and stone powder having a thickness of 5 mm or less, and then mixing the mixture. After the addition, the water-permeable block described above is put on the upper portion and pressurized, followed by curing to produce a highly elastic water-permeable block as a whole. In addition, in order to enhance the strength, the top coating of the transparent urethane or the transparent epoxy having a hardness of 70 or more may be sprayed on the surface after curing.

Hereinafter, the elastic panel mounting method of the present invention will be described based on the drawings.

1 is a schematic diagram of a road paved by the present invention. As shown in the configuration of Figure 1, the high-elastic road paving method of the present invention is to install an elastic layer made of urethane and crushed waste concrete chips on top of the base layer laid by a conventional method, the elastic panel on the top To install it. Since the elastic panel forming the surface layer may be colored in various colors, it may also serve to enhance the beauty of the surroundings.

Figure 2 is an exploded perspective view showing an elastic panel manufacturing apparatus, Figure 3 is a perspective view showing a manufacturing apparatus of the resilient panel. Referring to Figure 2, looking at the configuration of the elastic panel manufacturing apparatus, the mold 2 is placed on the bottom plate 1 of a predetermined size and the pressure plate 3 is installed on the upper part of the mold 2, the elastic mixture After the input, the surface is cleaned up, the pressing plate is removed, the mold is removed, and the panel 4 is lifted from the lower bottom plate 1 and used in the field.

Looking at the configuration of the resilient elastic panel manufacturing apparatus with reference to Figure 3, the mold (6) which is installed in parallel to a certain width on the belt conveyor (5) moving at a constant speed is seated, the mixture inside the mold (6) A hopper 7 is installed at one end of the belt conveyor 5 so as to insert the roller, and a roller 8 is installed at the bottom of the belt conveyor 5 so as to pressurize the mixture introduced into the mold 6.

Hereinafter, the field installation type elastic packaging method of the present invention will be described. In the field installation type elastic packaging method of the present invention, a step of forming a base layer by a conventional method, a process of spraying a polymer for adhesion strengthening on top of the base layer, urethane-coated pulverized waste tire chip or urethane chip Mixing together and laying the mixture to form an elastic layer, covering the vinyl on the upper part of the elastic layer and roller compacting the upper part of the vinyl, and removing the vinyl after curing of the elastic layer is completed. It includes a step of coating with a urethane or epoxy on the elastic layer.

A detailed description of each process of the field installation type elastic packaging method of the present invention is as follows.

First step: base layer formation process

It is a process of forming a foundation layer by laying and curing foundation concrete, permeable concrete, ascon, sidewalk block, etc. by a conventional method, or by forming a foundation layer by washing the upper surface of an existing concrete pavement. A premise for high elastic packaging is the process of forming the foundation layer. The high elastic paving method of the present invention can be applied not only to newly laid roads, but also to the upper surface of existing concrete pavement. In the case of using the existing package, the surface of the package is washed with water to completely remove foreign substances. In case of permeability, permeability should be secured by using a suction cleaning method or a high pressure lake in order to reduce permeability voids. In addition, in the case of using the existing sidewalk block it is preferable to remove the foreign substances on the surface of the sidewalk block by using a spray or blower, cutting the pavement section to compact the roller to sit down the pavement surface. On the other hand, in the application of the method of the present invention, if you want to install the road as a whole permeable, it is possible to install the underlying base layer permeable.

Second Process: Polymer Spraying Process

The process of drying the surface of the base layer formed in the electrical process and then spreading either the epoxy primer or the urethane primer, which is a binder for firmly bonding the elastic layer and the underlying base layer laid in the next process Epoxy primer or urethane primer may be applied to the upper surface of the base layer. Epoxy primer or urethane primer should be sprayed after the upper surface of the base layer is dried, the spray amount is preferably 0.2 ~ 2kg / ㎡. However, in the case where the foundation layer is made of a permeable concrete layer (a large number of surface voids are formed), the urethane or the like of the elastic layer to be placed on top may penetrate into the voids so that the two layers can be firmly bonded, so that the primer May be omitted.

Third Step: Elastic Layer Forming Process

Lay out the waste tire chip, urethane or rubber chip which is mixed with less than 0.01 parts by weight of urethane with respect to 1 part by weight of the waste tire pulverized on the top after drying the primer sprayed in the electrical process to a thickness of 30 mm or less To form an elastic layer. As described above, in order to coat urethane on the pulverized waste tire chip, the pulverized waste tire chip should first be heated to 50-150 ° C. to gel its surface. However, due to the high cost of urethane chips, the urethane chips and urethane-coated crushed waste tire chips may be mixed at an appropriate ratio in consideration of the construction site, or the entire amount of crushed waste tire chips may be coated with urethane instead of urethane chips. Can also be used as In this step, in order to enhance the strength, 3 parts by weight or less of silica sand having a diameter of 5 mm or less may be mixed and used in this step.

4th process: Roller compaction process covering vinyl

The process of covering the vinyl on top of the elastic layer of the electrical process and roller compacting the vinyl top is a step of surface cleaning and compacting the elastic layer. As described above, if the elastic layer is not covered with vinyl, the material of the elastic layer is attached to the compacting roller, so that the roller cannot be smoothly compacted. In order to prevent the adhesion of the trowel or the roller was used, thereby causing a problem that the surface is uneven and the surface strength is lowered. This process solves the conventional problem by covering the vinyl of the property which is not adhere | attached with urethane. In addition, when the vinyl is covered as in the present process, rainwater can be prevented from being used as an elastic layer during rainy weather, so that curing can be performed smoothly. Covering the vinyl and finishing the roller compaction, the state is left to cure for about a week, and then the vinyl is rolled out. The material of the vinyl is PE or PP, which has a property of not being adhered well due to its material property, so that it can be easily rolled out when the vinyl is rolled out.

5th process: Top coating process

When curing of the elastic layer is completed after the compaction of the roller, the process of removing the vinyl and coating the urethane or epoxy on the upper part of the elastic layer, which is a hardness of 70 or more on the surface of the elastic layer to increase the surface strength of the elastic layer A top coat of clear urethane or clear epoxy is applied. In addition, the coating agent may be used by further mixing the pigment of the color in order to produce a variety of colors.
