In order to use municipal solid waste incineration (MSWI) bottom ash powder (BAP) and bottom ash aggregate (BAA) in asphalt mixture, AC-13 containing 100% (by mass) BAP or 20% (by mass) BAA (0-9.5mm) 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 mix is better than that of BAP mix, and the control mix is the worst. Furthermore, BAP and BAA also can reduce the decrease of TSR and increase the shear strength ratio throughout the freeze-thaw cycles. That is because, the properties of BAP and BAA help enhance the adhesion between them and asphalt, and enlargement the internal friction angle of the mix, leading to better structural strength.
