Abstract

The invention discloses an environment-friendly nonslip ultrathin seal material and a preparation method thereof and solves the problems that the asphalt pavement has water penetration, poor slip resistance, slightly pitted surface and small cracks. A stable durable seal is provided to protect the asphalt pavement, aggregate of an original asphalt pavement can be locked, oil shortage can be repaired, post-construction traffic opening time is short, little influence is caused to transportation, and the material herein has great technical significance and social significance; the preventive maintenance process used herein helps maintain pavement service level and retard maintenance time of extensive and medium repair, and save lifecycle maintenance cost.

Description

technical field [0001] The invention relates to the technical field of road building materials, in particular to an environment-friendly anti-skid ultra-thin sealing layer material and a preparation method thereof. Background technique [0002] The performance attenuation of the asphalt pavement surface, insufficient anti-skid performance, secondary diseases such as micro-cracks, pockmarks, threshing and water seepage of the pavement seriously affect the service level, driving safety and service life of the pavement, especially for the aging of the pavement caused by ultraviolet rays. The durability of the asphalt pavement is insufficient, and many preventive maintenance processes at this stage cannot solve the problem very well. There is an urgent need for a preventive maintenance process that can solve various minor diseases of asphalt pavement, so as to solve the problem of excessive water seepage coefficient, insufficient skid resistance, Environmentally friendly cold co...
