Application and Mechanism of a New Type of Polyethylene Modifying Additive in Asphalt Mixture

Article Preview

Abstract:

Asphalt mixture is often modified by adding modifier in order to improve the pavement performance such as high temperature stability, low temperature crack resistance and water stability. The author applies a new type of polyethylene modifying additive for asphalt mixture. The adding method of modifier is different from traditional method. Three modifiers were used in this study. It has been found that each modifier can improve the asphalt mixture performances. The author analyses the reason why modifying additive can improve asphalt mixture performances and give an advice to choose the type of modifying additive.
