Generally, asphalt binder modifier increases the viscosity at high temperature as well as at mixing and paving temperature, so that higher temperature is required to produce the hot-mix asphalt. Otherwise, wax is able to improve workability by means of decreasing the viscosity of asphalt binder. In this study, the effect of PE wax used to modify the asphalt binder was evaluated in laboratory. The properties of PE wax modified binder were compared with those of SBS and Crumb Rubber Modified binders. The results showed that wax type I has an effect on strengthening rut resistance as well as improving workability. However, wax type I weaken crack resistance due to making binder harder at intermediate temperature. The results also showed that wax type II has an effect on improving workability and on strengthening crack resistance due to making binder softer.
