The Development, Implementation, and Use of ASTM C1701 Field Infiltration of In Place Pervious Concrete

Source

In place pervious concrete begins its design life with an initial infiltration rate that is in part determined by the mixture proportions and compactive effort. This means that both the producer and the contractor influence the final infiltration rate of the pervious concrete. It was this fact that led to the development of a field based ASTM method to determine what pervious concrete infiltration rate was being constructed. Other researchers have investigated field infiltration to determine pollutant removal, hydrological performance, clogging potential, and water quality. It was necessary to have a test that could monitor a pervious concrete pavement over time in relation to maintenance, because so many pervious projects had already been placed across the United States. ASTM C1701 was adopted in June 2009, and engineers are beginning to understand the usefulness of such a test method. This paper focuses on the methodology, showcasing projects that have used the test method and correlating existing pervious placements with current infiltration data to determine a best practices design infiltration rate. Additionally, an investigation into possible maintenance techniques is discussed for situations in which a clogged placement is encountered.
