Abstract

The invention discloses a high-modulus and high-elasticity asphalt additive, a preparation method thereof and application thereof. The high-modulus and high-elasticity asphalt additive comprises the following components in part by mass: 100 parts of polymer resin, 40 to 60 parts of filler and 20 to 40 parts of softener, wherein the polymer resin is a mixture of low-density polyethylene, high-density polyethylene and polycarbonate in a mass ratio of (1-1):(0.1-2):(0.05-0.5); the softener is dioctyl terephthalate; and a promoter is dibenzyl dithiocarbamate zinc. The preparation method comprisesthe following steps of: mixing the polymer resin and the filler uniformly at the temperature of between 145 and 170 DEG C; and adding the softener, an ultraviolet light screening agent and the promoter into a material obtained in the step a, and mixing uniformly at the temperature of between 180 and 195 DEG C and granulating, wherein the mixing amount can be selected according to different road sections. By the high-modulus and high-elasticity asphalt additive, the wheel rutting resistant performance, low-temperature performance and shear-resistant performance are better improved.

Description

technical field [0001] The invention belongs to the technical field of asphalt, and in particular relates to a high-modulus and high-elasticity asphalt additive, a preparation method and an application thereof, which are mainly used to improve the rutting resistance, low-temperature performance and shear resistance of asphalt pavement. Background technique [0002] In the past ten years, my country's asphalt pavement construction has developed rapidly. With the increasing traffic load, the early damage of asphalt pavement is serious, and rutting is the most serious damage form of asphalt pavement. Rutting is very common in heavily overloaded highways, bus stops on urban roads, intersections, and other places. Rutting affects driving safety, so that frequent repairs to the road surface are required, resulting in a waste of construction investment. [0003] The existing research results show that the rutting of asphalt pavement in my country is mainly caused by the low modulu...
