Summary:The influence of combination of low density polyethylene (LDPE) and petroleum resin on asphalt was investigated by analyzing the change of its penetration, ductility, softening point and viscosity. The results show that petroleum resin can significantly increase the viscosity of PE modified asphalt, which results in the improvement of the asphalt’s waterproof ability and anti-rutting performance in a certain degree. However, the ductility and softening point were negatively affected due to the addition of the petroleum resin. Through analyzing the penetration indexes, an optimal dosage of 8% PE and 5% petroleum resin can be determined, respectively.
