Municipal solid waste incineration( MSWI) bottom ash powder( BAP) was used to replace( 100% by mass) natural limestone powder in asphalt mixture,and its feasibility and effect on properties were discussed. Based on the designing of asphalt mixture proportion,the effect of BAP on design asphalt content and Marshall index was also studied. Pavement performance of asphalt mixture with BAP was investigated by room testing. The results show that the design asphalt content and the Marshall stability will increase...
