Abstract: In order to study the application of recycled aggregate in water permeable concrete, two series of researches on the recycled aggregate concrete made from waste pavement concrete were designed to study the influence of the proportion of recycled aggregates in recycled pervious concrete(RPC). That is, the recycled aggregates with particle size of 9.5-19.0 mm replaced the same size natural aggregate by 0%, 25%, 50%, 75% and 100% (standard) quality, respectively(series1). And RPC was designed by two kinds of particle size aggregates with 4.75-9.5 mm, 9.5-19.0 mm according to the ratio of 0:1, 1:1, 1:2, 2:1, 2:3 and 3:2(series 2).With this basis, its physical, mechanical, water permeability and their relationship were analyzed, and the reasonable rate of recycled aggregate and double particle size ratio were obtained. In the 1:1 and 2:1 blending can get better strength and water permeability. The pore distribution characteristics and trends were analyzed by the image processing of the cutting test block, and the plane porosity, equivalent pore size and water permeability coefficient were correlated. The results show that the number and area of cross-section pores play a key role in the permeable capacity of recycled pervious concrete.
