Abstract

The invention provides an asphalt temperature performance reinforcing agent, a production method and applications thereof. The reinforcing agent is composed of the following components in parts by weight: 20 to 50 parts of recycled waste plastic particles, 5 to 30 parts of inorganic particle master batch, 10 to 40 parts of hard asphalt, 10 to 40 parts of waste tire rubber powder, and other auxiliary agents. The provided reinforcing agent can prominently improve the high-temperature performance of asphalt mixture, while the low-temperature performance of the asphalt mixture is not affected at the same time. The problem that the asphalt road is not stable at a high temperature is solved, the road surface can maintain an excellent performance at a high temperature, and the happening rate of track damages is greatly reduced.

Description

technical field [0001] The invention relates to the field of asphalt, in particular to an asphalt temperature performance enhancer, its production method and application. Background technique [0002] With the rapid development of my country's transportation construction, the axle load and the number of vehicles are constantly increasing, which puts forward higher requirements for road materials. The heat emission from the car body and the friction between the wheels and the road surface further increase the road surface temperature, which puts a more severe test on the road surface in the high temperature environment in summer. [0003] At this stage, the most common and most difficult problem to solve on asphalt pavement is pavement rutting disease. The use performance and service efficiency of pavement are closely related to pavement disease, and seriously affect the safety of driving. The most common type is unstable rutting, which is caused by the lateral displacement...
