ABSTRACT
The Environmental Protection Agency’s (EPA) National Pollutant Discharge Elimination System (NPDES) permitting has required implementing best management practices (BMPs) to reduce stormwater volume and a portion of the pollutants contained therein (U.S. Gov 2004). Portland Cement Pervious Concrete (PCPC) is becoming a wide-spread stormwater BMP and has the potential to produce safer and quieter driving surfaces. One of the quietest pavements in use today is pervious concrete (Bax et al. 2007). In the past poorly designed pervious concrete mixtures and contractor inexperience with pervious concrete have resulted in overly manual-labor intensive construction, which increases cost and can negatively impact durability. Methods to improve placement rates and quality include newequipment andmore advanced concretemixture designs. Improved construction techniques specifically tailored to PCPC’s idiosyncrasies can reduce placement crew size while increasing finished product quality. Mechanized placement has the potential to reduce labor and produce amore consistent final product. Newly developed equipment and modifications to existing equipment allow rapid pervious concrete placement using slipform pavers and laserguided screeds. Experience with PCPC is allowing development of proven design guidelines. On-going research is integrating new designs and admixtures to tailor mixture properties to specific placement requirements.
