Performance of high density polyethylene and styrene butadiene styrene modified asphalt concrete mixture under high temperature

The purpose of this study is to evaluate the performance of a mixture of asphalt concrete (AC) modified with high density polyethylene (HDPE) and styrene butadiene styrene (SBS) in high temperature environments. The performance of three types of AC mixtures with 60/70 penetration grade bitumen, HDPE, and SBS modifier is analyzed based on the Marshall stability, moisture damage resistance, static modulus, and wheel tracking test. It has been noted that at high temperature conditions, the HDPE and SBS modified AC mixture may significantly increase the Marshall stability, static modulus, rutting resistance, and moisture damage resistance.
