<p align ="justify">Failure of road pavement in Indonesia is mostly due to climate variation (temperature and rainfall) and traffic load. The aim of this research are to get Marshall Empirical performance evaluation, Dynamic Modulus and Resilient Modulus of AC-WC mixture Pen 60/70 with SBS polymer modified asphalt. The asphalt used in this research are asphalt Pen 60/70 and SBS polymer modified asphalt with percentage of 3% and 4,5%. The basic properties of asphalt and aggregates were measured by standard test, based on Indonesia’s Standard of Hot-mix asphalt mixture, while the performance of mixture was measured by Standard Marshall test, Marshall Immersion test, UMATTA’s Resilient Modulus Test, and AMPT’Dynamic Modulus Test. Mixture Performance according to Marshall test shown that the highest value of Marshall stability were (1007 Kg) for AC-WC mixture with 3% SBS and also the result of Marshall Immersion test shown that the highest value of 98,13% was on AC-WC mixture with 3% SBS. Dynamic Modulus AC-WC mixture with 0% SBS value higherst than others at low temperature (4°C) (1792,7 MPa) whereas Dynamic Modulus AC-WC mixture with 3% SBS value higherst than others at high temperature (45°C) (61,8 MPa). The result of Resilient Modulus using UMATTA at 20°C shown that the highest value 5812 MPa (AC-WC mixture with 3%) SBS and 408 MPa (AC-WC mixture 4,5% SBS) at 45°C. The result of this research shown than SBS modified asphalt mixture had a better performance at high temperature. Generally, AC-WC mixture with 3% SBS had better than others. The addition of modified polymer SBS can improve the performance of mixture,<p align ="justify">
