Abstract

The invention discloses a multifunctional ultra-thin surface layer material for roads and an application thereof, belonging to the field of road engineering. The surface layer material includes multifunctional composite filler, modified oil-resistant asphalt and mixture, and the multifunctional composite filler is composed of slaked lime, sodium chloride, aluminum hydroxide and mineral powder; the modified oil-resistant asphalt is composed of long Composition of alkyl silicone oil, glycerin and SBS modified asphalt. Compared with the prior art, the road ultra-thin surface layer paved with the multifunctional ultra-thin surface layer material for roads of the present invention has the properties of ultra-thin, anti-skid, noise reduction, ice-melting, flame-retardant, oil-resistant, anti-rutting, etc. Features, it can be used for both new road construction and old road maintenance, and has good promotion and application value.

Description

technical field [0001] The invention relates to the field of road engineering, and specifically provides a multifunctional ultra-thin surface layer material for roads and its application. Background technique [0002] Although my country's highway construction is developing rapidly, due to its late start, compared with the economy that has already taken off for decades, my country's highway construction still cannot keep up with the pace of economic development. Therefore, we still need to invest more funds to increase the number of new roads. At the same time, the speed of construction is too fast, so that the supervision of project quality is not in place, so that many new roads in our country are damaged to varying degrees after a few years of use, far from reaching the normal service life of the roads, so they have to be overhauled in advance. Coupled with the rapid growth of traffic volume brought about by the rapid economic growth and the large-scale and heavy-duty of...
