Inordertostudytheeffectofcementsubstitutingmineralpowderontheperform-ance of rubber asphalt mixture， through immersion Marshalltest， freezethaw splitting test， indoor rutting test， low temperature bending test and uniaxial compressive strength test， the effect of different cement content substituting mineral powder on the performance of rubber asphalt mixture was studied.The results show that cement substituting mineral powder can significantly improve the water stability， high temperature performance and u-ni axial compressive strength of rubber asphalt mixture.The addition of cement has nosig-nificant effect on low temperature performance.The rubber asphalt mixture with cement content of 2%~4%has the best water stability.The effect of high temperature stability and compressive strength of rubber asphalt mixture with cement content of 4%is the most obvious.Considering cement substituting mineral powder， the optimum content of rubber asphalt mixture is 2%~4%.The research results can provide references for the best content of cement substituting mineral powder to improve the performance of rubber asphalt mix-ture in different areas.
