Problems solved by technology

In the cold season, the accumulated water freezes, and the anti-skid performance of the road surface will be greatly reduced, which will affect driving safety.
Moreover, the traditional glass asphalt mixture is easy to be crushed due to broken glass in the aggregate, and has low stability. The road surface is prone to rutting and cracking and other diseases, and the existence of broken glass will affect construction safety. Easily scratched by broken glass

Abstract

The invention discloses anti-rutting asphalt. The anti-rutting asphalt is characterized by being prepared from 8-15 parts by weight of low-mark hard asphalt with needle penetration of 15-35 dmm, 20-30parts by weight of mineral powder, 20-30 parts by weight of crushed stone, 5-10 parts by weight of porous reflective glass microspheres, 0.5-1.5 parts by weight of a fiber stabilizer, 50-68 parts byweight of aggregate, 0.5-1 part by weight of an anti-stripping agent and 1-8 parts by weight of a modifier, wherein the modifier is a mixture of chlorinated polyethylene rubber and a thermoplastic elastomer in a weight ratio being 2-6:3-5; the low-mark hard asphalt is prepared from 45-65 parts of natural asphalt mother liquor, 2-4 parts of chlorinated polyethylene rubber and 35-55 parts of petroleum asphalt. The anti-rutting asphalt has the advantages of low cost, high density and strength and good anti-rutting effect, strength, stability and durability, and anti-stripping performance and reflectivity of an asphalt mixture can be improved.

Description

technical field [0001] The invention relates to an asphalt, in particular to an anti-rutting asphalt. Background technique [0002] The road performance of the asphalt pavement deteriorates rapidly due to the rutting, pushing, wave, and wrapping caused by the heavy load of the asphalt pavement. These problems mainly occur on the driving lane. It will cause the vehicle to shake from side to side and cause discomfort to passengers. When the rut reaches a certain depth, it is enough to accumulate water in the wheel track, which will cause water damage to the asphalt pavement, and at the same time, it will easily cause water drift for vehicles driving fast on it. In the cold season, when the accumulated water freezes, the anti-skid performance of the road surface will be greatly reduced, which will affect driving safety. Moreover, the traditional glass asphalt mixture is easy to be crushed due to broken glass in the aggregate, and has low stability. The road surface is prone t...
