Rules and parameters of mix design for pervious recycled concrete were proposed. Making use of proportioning mix method for stone matrix asphalt (SMA) and open graded friction course (OGFC), volume indexes including volume of voids(VV), volume of cement paste (VP) as well as percent air voids in coarse aggregate(VCA) can be seen as key parameters guiding for mix design. Mix design procedures for pervious recycled concrete were then put forward. Both compressive strength and water seepage velocity were put forward as verification indexes. A practical mix design example was given and the compressive strength and VV test result show that the new mixing design method for no-fines pervious recycled concrete or conventional pervious concrete is practical and feasible.
