Performance Evaluation of Waste High Density Polyethylene as a Binder Modifier for Hot Mix Asphalt

In recent years, waste materials as alternative raw materials have been increasingly utilized in asphalt concrete (AC) mixtures to reduce environmental pollution, decrease construction costs. The main purpose of this study was to investigate the possibility of using waste high density polyethylene (HDPE) as polymer additives for hot mix asphalt (HMA) mixtures. To accomplish this objective, the different HDPE contents (6, 8, 10, 12, and 14 wt%) were used to modify a conventional 60/70 penetration grade bitumen. A virgin polymer (styrene–butadiene–styrene) modified base asphalt was also used as reference binder since it is the most commonly used for binder modification. The Marshall stability (MS), indirect tensile (IDT), moisture damage resistance, wheel tracking (WT) test, four-point bending beam fatigue test, and semi-circular bending (SCB) fracture tests were conducted to evaluate the performance resistance of HDPE modified asphalt binder for HMA mixtures. The test results applied to asphalt mixtures indicated that the addition of HDPE increased rutting resistance at high temperature and cracking resistance at intermediate temperature significantly. In addition, it was found from the moisture resistance test that asphalt mix modified with 8 and 10% HDPE content has the highest TSR value in all modified mixtures. Based on the four-point bending beam fatigue and semi-circular bending (SCB) fracture tests, it can be recommended that the HDPE content of 8% by base asphalt weight can be utilized as a modification to base binder in HMA mixture.
