Construction method and structure of antiskid surface of pavement

Abstract

The invention discloses a construction method and structure of an antiskid surface of a pavement and belongs to the technical field of construction of the antiskid surface of the pavement. The structure comprises drainage layers laid on the two sides of the pavement, an upper surface layer, a middle surface layer and a lower surface layer are sequentially laid between the drainage layers on the two sides from top to bottom, and an antiskid surface layer located above the drainage layers is laid on the upper surface layer. The preparation method of the antiskid layer comprises the following steps of: S1, heating asphalt to 90-110 DEG C for softening the asphalt; S2, stirring and mixing limestone and diabase to form a mixture, and heating the mixture to 175-185 DEG C; and S3, stirring the softened asphalt and the mixture for 5-10 minutes to form the antiskid surface layer. The structure is simple in structure, forms the antiskid surface on the pavement, enhances the antiskid capacity of the pavement, and improves the strength of the pavement.

Description

Technical field [0001] The invention belongs to the field of construction technology of road surface, and is specifically a construction method of the road surface anti-slide surface and its structure. Background technique [0002] In recent years, the highway has increased rapidly in the national road network, and the number of road trips has also increased sharply. Although most roads in the early buildings are complete, and the road surface anti-slide performance has been greatly reduced. Some Even unable to meet the requirements of use, there is a large safety hazard, in order to ensure the safety of the motorway, improve the road surface anti-slip performance is especially important. [0003] The situation in which the road surface is slidably reduced includes: First, after the new road is opened for a certain period of time, the road naked stone is gradually being polished, wear, plus the asphalt concrete surface layer due to wheel accumulation, and reduces roughness Howeve...

AI Technical Summary

Problems solved by technology

[0002] In recent years, the proportion of expressways in the national road network has increased rapidly, and the number of road travelers has also increased sharply. Although most roads built in the early days have structural integrity, the anti-skid performance of the road surface has been greatly reduced. Some It can't even meet the requirements of use, and there is a big safety hazard. In order to ensure the driving safety of the expressway, it is particularly important to improve the anti-skid performance of the road surface.

[0003] The conditions that lead to the reduction of the skid resistance of the road surface include: First, after the new road surface has been opened to traffic for a certain number of years, the exposed stones on the road surface are gradually polished and worn by the wheels, and the asphalt concrete surface is compacted due to the cumulative effect of the wheels, and the roughness is reduced. , resulting in a decrease in the anti-skid performance; the second is that the drainage of the road surface in rainy days is not timely, and the excessive water accumulation leads to the appearance of water drift and water mist, thereby reducing the friction between the wheels and the road surface, resulting in a decrease in the anti-skid performance of the road surface
