Abstract This paper presents the effect of replacement level of natural aggregate (crushed limestone aggregate, LS) with Recycled Concrete (RC) and coal Bottom Ash aggregates (BA) on pervious concrete properties. Mechanical properties, thermal conductivity, and sound absorption of pervious concrete were tested. Results showed that the compressive strength of BA pervious concrete was excellent and comparable to that of LS pervious concrete. While the compressive strength of RC pervious concrete was slightly reduced to between 85 and 99% of that of LS pervious concrete. The thermal conductivity and sound absorption of pervious concretes containing RC and BA were significantly improved compared to those of pervious concretes containing conventional LS.
