Abstract

The invention discloses a multifunctional ultrathin surface layer material for roads and application thereof, and belongs to the field of road engineering. The surface layer material comprises multifunctional composite filler, modified oil-stain-resistant asphalt and a mixture, and the multifunctional composite filler is composed of slaked lime, sodium chloride, aluminum hydroxide and mineral powder; the modified oil-stain-resistant asphalt is composed of long-chain alkyl silicone oil, glycerin and SBS modified asphalt. Compared with the prior art, the road ultra-thin surface layer paved by the multifunctional ultra-thin surface layer material for the roads has the characteristics of ultra-thinness, skid resistance, noise reduction, ice melting, flame retardance, oil stain resistance, rut resistance and the like, can be used for new pavement construction and old road maintenance, and has very good popularization and application values.

Description

Technical field[0001]The present invention relates to the field of road engineering, in particular to provide a multi-functional thin surface layer material for roads and their applications thereof.Background technique[0002]Although my country's road construction industry is developing rapidly, due to late start, my country's road construction industry still does not follow economic development. Therefore, we still have to invest more funds to increase the number of new roads. At the same time, the speed of construction is too fast, which makes the quality of the project are not in place, so that many new roads in my country have different degrees of destruction, far from the normal service life of the road, so that overhaul in advance. In addition, the rapid growth of the rapid economic growth and the large-scale vehicles are large, and the overloading has caused the road to break. This has caused my country's current stage in China, and there is more than two "more than two" more ...
