Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the above asphalt pavement structure has a problem in that its water permeability is low, and rainwater accumulates on the road during rainy days, which hinders the driving of vehicles such as automobiles and the walking of people.

[0006] In addition, the construction of the surface layer of the asphalt pavement is carried out by supplying a heated asphalt mixture onto a roadbed formed on the ground and spreading the asphalt mixture evenly using an asphalt finisher. During the construction of the asphalt pavement, heating processes such as heating the asphalt mixture are required, and from the perspectives of preventing global warming and suppressing construction costs due to the soaring crude oil prices, it is desirable to suppress the heating process as much as possible.

[0007] The present invention uses crushed waste materials, can prevent global warming through the effective utilization of resources, has excellent water permeability, and does not allow rainwater to accumulate even during rainy days, providing a pavement that does not cause obstacles to vehicle driving or pedestrian walking.

Means for Solving the Problems

[0008] The pavement of the present invention comprises a ground, and a surface layer laid on the ground and containing crushed waste materials.

[0009] In the above pavement, the crushed waste materials are characterized by containing crushed tile or crushed brick.

Effects of the Invention

[0010] Since the surface layer laid on the ground of the pavement of the present invention contains crushed waste materials and uses the crushed waste materials, energy conservation can be achieved in the manufacturing process of the raw materials of the pavement through the effective utilization of resources, contributing to the prevention of global warming.

[0011] The pavement of the present invention has a surface layer containing crushed waste materials and can drain water through the gaps between the crushed waste materials, suppressing the accumulation of rainwater on the surface of the pavement during rainy days and preventing situations that would hinder vehicle driving or pedestrian walking.

[0012] Since the surface layer of the paving structure of the present invention contains crushed waste, when walking on the surface layer, the crushed waste is displaced relatively, and at the time of this relative displacement, frictional sounds between the crushed waste are generated. Therefore, it is possible to notice that someone is walking on the paving structure, and a crime prevention effect can be achieved.

[0013] In the paving structure of the present invention, when the crushed waste contains crushed tiles or crushed bricks, the crushed tiles or crushed bricks can absorb moisture in the air, or the moisture absorbed by the crushed tiles or crushed bricks can be discharged into the air, and the amount of moisture in the air on the paving structure can be controlled, and a comfortable life can be led on and in the vicinity of the paving structure.

Brief Description of the Drawings

Embodiments for Carrying Out the Invention

[0015] An example of the paving structure of the present invention will be described with reference to the drawings. The paving structure A includes a ground B and a surface layer C that is laid on the ground B and contains crushed waste.

[0016] The ground B of the paving structure A may be the ground surface or a roadbed formed on the ground surface. The roadbed is constructed in a known manner. The roadbed can be constructed by excavating the ground surface (original ground) and leveling the floor.

[0017] The surface layer C is laid on the ground B to construct the paving structure A. The surface layer C is constructed by rolling and spreading the crushed waste C1 with a rolling device such as a vibrating roller. Different from the conventional asphalt paving structure, it does not require a roadbed on the roadbed, and the construction period of the paving structure can be shortened.

[0018] As the crushed waste C1, for example, crushed tiles, crushed bricks, etc. are preferably used. As for tiles, there are unglazed tiles obtained by directly firing a molded body formed by shaping clay into a tile shape in a kiln, and glazed tiles obtained by applying glaze to a molded body formed by shaping clay into a tile shape and then firing it. Any type of tile can be used.

[0019] Bricks are made by kneading clay, shale, and water together, putting them into a mold, and firing them until they are hardened. As bricks, ordinary bricks and facing bricks defined in JIS R1250:2011, and paving bricks defined in JIS A5215:2014 can be used.

[0020] The tiles and bricks used as raw materials for the crushed material are those used in houses, buildings, etc., and the waste tiles and waste bricks generated along with the demolition of houses and buildings are used. By doing so, there is no need to newly manufacture tiles and bricks. By recycling the waste tiles and waste bricks that have been conventionally discarded, energy conservation can be achieved, and global warming prevention can be achieved.

[0021] The crushed waste C1 can be manufactured by crushing waste such as tiles and bricks in a known manner. The size of the crushed waste C1 is not particularly limited, but 20 - 35 mm is preferable, and 25 - 30 mm is more preferable. By setting the size of the crushed waste C1 within the above range, sufficient strength can be imparted to the surface layer, and the surface layer can be given sufficient strength to withstand the driving of vehicles or the passage of people on the surface layer surface. An appropriate gap can be formed in the thickness direction of the surface layer between the crushed waste C1s that make up the surface layer. Through the gaps formed between the crushed waste C1s, the moisture supplied onto the surface layer during rainy days or by sprinkling can be smoothly discharged from the surface layer surface, and unexpected situations that would hinder the driving of vehicles or the walking of people can be avoided. Note that the size of the crushed waste C1 refers to the diameter of the smallest sphere that can surround the crushed waste.

[0022] Tiles and bricks are porous materials having innumerable voids inside, and by utilizing the innumerable voids formed inside, they can absorb moisture in the air or discharge the absorbed moisture. Therefore, in or near the paving body A, the amount of moisture in the air can be easily controlled so as to provide a comfortable amount of moisture to the human body.

[0023] In summer, even when the temperature of the surface layer rises due to sunlight irradiation, the temperature rise of the surface layer can be mitigated by the action of the moisture contained in the tiles or bricks. Therefore, in or near the paving body A, the rise in air temperature can be mitigated.

[0024] Also, the surface layer C is constructed by rolling and laying the crushed waste C1 with a rolling device such as a vibrating roller, and fine irregularities resulting from the crushed waste are formed on the surface of the surface layer. In the surface layer C, sunlight undergoes diffuse reflection, and it is possible to reduce the poor visibility due to the reflected sunlight and suppress interference with the driving of vehicles and the walking of pedestrians.

[0025] Next, the construction procedure of the paving body A of the present invention will be described. The paving body A is constructed by forming the surface layer C on the ground (original ground) or on the ground B such as a roadbed formed on the ground. The ground B only needs to be capable of stably laying the surface layer C thereon with a predetermined thickness.

[0026] The ground (original ground) on which the paving body A is formed is not particularly limited. For example, in addition to the ground on which roads or parking lots are constructed, the ground on which buildings such as condominiums, complex facilities, and detached houses are constructed (the part where no building is constructed) can be mentioned.

[0027] The paving body A can be constructed by laying the surface layer C by laminating the crushed waste on the ground B. When laying the surface layer C on the ground B, there is no need for a roadbed constructed in an asphalt paving body, and the paving body A can be constructed by directly laying the surface layer C on the ground B.

[0028] After spreading (leveling) the crushed waste C1 on the ground B, the surface layer C can be constructed by compacting the crushed waste C1 using a general-purpose compaction machine such as a road roller or a tire roller. As described above, the pavement A can be easily constructed by laying the surface layer C on the ground B in a known manner using the crushed waste C1.
