This work investigated using recycled concrete aggregate (RCA) in pervious concrete,
4 specifically the effects on the density, strength and permeability. Cylindrical specimens of
5 pervious concrete with different percentages of RCA and conventional aggregate were cast. The
6 coarse aggregate was substituted by 0, 10, 20, 30, 50, and 100% RCA. As percent RCA
7 increased both compressive strength and permeability generally decreased. The strength and
8 hydraulic characteristics of mixes examined in this study compared generally well with other
9 studies, on pervious concrete without RCA, found in the literature. The results indicate that up to
10 50% substitution of course aggregate can be used in pervious concrete without compromising
11 strength and hydraulic conductivity significantly. Further testing evaluating freeze-thaw
12 durability is necessary if pervious concrete with RCA isto be used in cold weather climates.
