Title: Hitting the Mark
Author(s): John Kevern and Jereme Montgomery
Publication: Concrete International
Appears on pages(s): 45-48
Keywords: pervious concrete, quality assurance, void content, infiltration rate
Abstract:Pervious concrete mixtures are generally proportioned to have 15 to 25% air void contents to ensure adequate infiltration rates and strength. New ASTM standards for determining density and void content as well as infiltration rate were recently used as part of the quality assurance program for the construction of a parking lot in Omaha, NE. Test placements were used to develop a compaction-density relationship for test samples, and this was correlated to the void contents of pavement samples. Workability tests and unit weight tests were used to screen loads to ensure that concrete was workable and could be consolidated to achieve a target air void content. Test cores taken after the pavement hardened showed that the quality assurance testing program was successful.
