Problems solved by technology

[0003] With the increase of asphalt pavement use time, the surface of some common aggregates (such as limestone) will be polished, and its skid resistance will decrease, which will affect driving safety
In addition, after long-term action by vehicles, the surface adhesion of ordinary aggregates will be greatly reduced, which will cause asphalt and aggregates to peel off, resulting in road surface diseases such as rutting, oil flooding, and water damage.
[0004] Now most of the common aggregates are used as fillers, so that the asphalt pavement will reduce the skid resistance of the pavement under the long-term vehicle load, increase the depth of the surface structure, and cause serious oil and water damage.

Abstract

The invention relates to a permanent asphalt pavement anti-skid wear layer, comprising: high-performance aggregate, ordinary aggregate, and asphalt mixture; wherein, the polishing value of the high-performance aggregate is ≥ 50, and the wear value is 13-18%. ; The polishing value of the common aggregate is >42 and <50, and the abrasion value meets the specification requirements. The present invention blends high-performance aggregates and ordinary aggregates, and the ordinary aggregates and high-performance aggregates have a tight intercalation force, which increases the overall skid resistance of the road surface. As the use time increases, the performance of the high-performance aggregates The polishing value remains almost unchanged, and the performance indicators measured on the road surface, such as the swing value and the depth of the structure, have little attenuation change. The anti-slip performance of the road surface is extended, the driving safety is greatly improved, and the durability is also improved.

Description

technical field [0001] The invention belongs to the field of pavement anti-skid and wear layers, in particular to a permanent asphalt pavement anti-skid wear layer. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] With the increase of asphalt pavement use time, the surface of some common aggregates (such as limestone) will be polished, and its skid resistance will decrease, which will affect driving safety. In addition, after long-term action by vehicles, the surface adhesion of ordinary aggregates will be greatly reduced, which will cause asphalt and aggregates to peel off, resulting in road surface diseases such as rutting, oil flooding, and water damage.
