Abstract

PROBLEM TO BE SOLVED: To provide asphalt paving continuous of high water permeability and low noise for a long time. SOLUTION: With reard to asphalt paving including high water permeability together with low noise, a fine particle material of high permeability is disseminated and press fitted by 0.05 to 5.0kg/m<2> on the pavement body 1 surface apt to cause gap clogging and smashing impeding effect thereof after placing it to use or forming a special permeable layer on the pavement body 1 surface by covering it with a high permeable material in the thickness of 0.1 to 5mm beforehand. Thus a pavement not deteriorating its permeable capability for a long time after putting it to use and continuous of its low noise property can be obtained by lessening room for foreigh matter to penetrate into and restraining aggregate 3 movement.

In the conventional drainage pavement, since the surface of the pavement is rough and uneven, and the voids are open, the sand and dust enter the pavement surface and clog the voids at the start of operation. In addition, since it is a pavement having a high porosity, it causes clogging of the voids due to traffic load,
There is a disadvantage that the water permeability decreases in a relatively short period of time. In order to eliminate the clogging of the gap, it is the current situation that foreign substances clogged in the gap are mechanically sucked and eliminated to recover.However, the number of machines and capacity are limited, It is difficult to recover only a part of the space, and there is no method for recovering from the collapse of the void. In the present invention, in order to eliminate this drawback, a special permeable layer is provided in advance on the pavement surface to fill in irregularities, reduce gaps, and reduce clogging of voids,
In addition to suppressing gap collapse and maintaining water permeability, during rainfall, foreign substances clogged in voids such as soil and dirt on the surface due to the action of running water etc. The present invention provides a drainage pavement that solves the problem by utilizing natural force, such as removing the foreign matter clogged in the voids and restoring the water permeability, and having a less decrease in water permeability than ever before.

Further, since clogging and crushing of the voids are small and a high porosity can be maintained, the low noise property of the drainage pavement can be maintained for a long time without being reduced.

It is a top view of the asphalt pavement structure upper surface of Claim 5 obtained by the asphalt pavement method described in. 1 is a mixture of aggregate 3, filler and asphalt, having a porosity of 10 to 40% and a water permeability of 1 × 10
It is a pavement that is spread and formed so as to be at least −2 cm / sec, and a part of the aggregate 3 is exposed on the surface. Reference numeral 2 denotes a fine-grained material having a particle size of 1 to 5 mm, which is sprayed on the pavement surface and press-fitted. The fine-grained material 2 sprayed and press-fitted fills the periphery of the aggregate 3 which is a concave portion of the pavement surface and covers the void portion.
As a result, there is less room for foreign substances, such as earth and sand and garbage, to enter the gap. Since the fine-grained material 2 itself has a sufficient water permeability, the water permeability does not change, and the water permeability is unlikely to decrease in the future.
In addition, since the unevenness of the pavement surface is reduced, foreign matters clogged in gaps such as earth and sand and dust on the surface are easily removed by the action of running water during rainfall, and the gap due to suction action when passing through the tire. The possibility of removing foreign substances clogged in the box increases. Further, since the fine-grained material 2 buried around the aggregate 3 functions to suppress the movement of the aggregate 3, the collapse of the gap is suppressed.

Since this coating layer 4 has a honeycomb-like structure or a structure in which countless pinholes are formed, clogging of voids is small. In addition to being easily removed by the action of the tire, the possibility of removing the foreign matter clogged in the gap by the suction action when passing through the tire increases.
Furthermore, since the strength of the pavement surface is reinforced and the movement of the aggregate is suppressed, the collapse of the gap is suppressed.

According to the asphalt pavement structure according to the present invention described in claim 5, which is obtained by the asphalt pavement method according to any one of claims 1 to 4, the surface of the asphalt pavement having water permeability is A material having high water permeability is sprayed and compacted and pressed in, or coated with a material having high water permeability. In conventional drainage pavement, since the pavement surface is rough and uneven, and voids are open, soil and dirt, dust, etc., enter the pavement surface at the start of operation, causing clogging of the voids and high porosity. Since it is a pavement having such a structure, there is a drawback that the space is collapsed by a traffic load, and the water permeability is reduced in a relatively short period of time. In order to eliminate the clogging of the air gap, it is the current situation that the foreign substances clogged in the air gap are mechanically sucked and eliminated to recover. However, the number and capacity of the machines are limited, and the overall recovery is limited. It is difficult to recover only a part of the space, and there is no treatment method for recovering from clogging of the voids. The special water-permeable layer fills the unevenness and reduces the gaps by reducing the gaps, suppresses the collapse of the gaps, maintains the water permeability, and at the time of rainfall,
Utilize natural force, such as removing foreign substances clogged in voids such as earth and sand and dust on the surface by the action of running water, etc., and removing foreign substances clogged in the voids by suction action through the tire to restore water permeability. To provide a drainage pavement with less decrease in water permeability than ever before.

Further, according to the present invention, since a high void ratio can be maintained with little void clogging and void collapse, the low noise performance of the drainage pavement can be maintained for a long time without lowering.

The asphalt pavement structure according to claim 5 obtained by the asphalt pavement method according to claims 1 to 4 according to the present invention is to be added to an extremely surface layer of a base asphalt pavement. Yes, it does not have any adverse effect on the asphalt pavement itself. Therefore, the function originally possessed by the base asphalt pavement is maintained as it is. For example, durability such as high water permeability, fluidity resistance, and abrasion resistance of the base asphalt pavement is maintained as it is.
