In order to use municipal solid waste incineration bottom ash powder(BAP) and bottom ash aggregate(BAA) in asphalt mixture, AC 13 asphalt mixtures containing 100%(by mass) BAP or 20%(by mass) BAA with particle size of 095mm were designed by Marshall test method. Based on splitting test after freeze thaw cycles, long term moisture susceptibility of asphalt mixture containing BAP or BAA was investigated. Structural strength was analyzed through uniaxial penetration test. The results show that BAP and BAA can make the designed asphalt content increase, and the Marshall test parameters all satisfy the standard demands. The long term moisture susceptibility of BAA asphalt mixture is better than that of BAP asphalt mixture, while the control asphalt mixture is the worst. Furthermore, BAP and BAA also can reduce the decrease of tensile strength ratio（TSR） and increase the shear strength ratio throughout the freeze thaw cycles. The properties of BAP and BAA help enhance the adhesion between them and asphalt, and increase the internal friction angle of the asphalt mixture and result in better structural strength.
