Study on Application of Waste Polyethylene and SBS in Modified Asphalt

摘要

In this paper, modified asphalt was prepared by using waste polyethylene and SBS. Through the performance test of modified asphalt, it was found that waste PE (Polyethylene) and SBS (Styrene-Butadiene-Styrene) modified asphalt had good physical and mechanical properties. Through the asphalt mixture's test, it was found that the waste polyethylene and SBS modified asphalt mixture had good high temperature stability, low temperature crack resistance and excellent fatigue performance.
