Abstract：Based on the trial calculation and Bailey method, this paper discusses the skeleton-void grading design method about the gradation design of recycled pervious concrete, among which three grading schemes are selected.The recycled coarse aggregates are preliminarily classified for the collocation with trial method,checking and analysis of the skeleton effect is conducted by the Bailey method.The results show that the CA ratio is 1.0~0.7, the recycled aggregate gradation of recycled concrete is easy to form the skeleton, and the skeleton structure is stable.The recycled aggregate ratio m (10~25 mm):m(5~10 mm)=64:36~80:20 is obtained as the optimal gradation range of recycled pervious concrete for guiding skeleton-void structure gradation design.
