In this paper,the recycled asphalt concrete AC-20 is taken as the research object.The effects of cement replacing mineral powder on the high temperature stability,water stability and low temperature stability of asphalt concrete were studied by Marshall test,freeze-thaw splitting test and low temperature splitting test.The test results show that cement has certain advantages as a filler,which can improve the high temperature stability and low temperature crack resistance of asphalt concrete.It is of great significance to improve the road performance of asphalt concrete and reduce the project cost.The research results can provide some reference significance for the recycling of waste asphalt mixture.
