A case study of a pervious concrete quality assurance ...

2010-3-12  Research and experience have shown thatpervious concrete mixtures proportioned to have 15 to 25% air voidcontents should have sufficient infiltration rates to limit storm watersurface runoff and adequate strength to avoid raveling. 1 Untilrecently, however, there were no U.S. standards for the verification ofair void content in fresh concrete or infiltration rates for in-placeconcrete.
