NRMCA Senior Director, Local Paving, Phil Kresge recently reviewed a proposed special provision for pervious concrete being developed by the Virginia Department of Transportation (VDOT). Separate from other VDOT specifications, this special provision is intended for use in low-volume traffic areas, such as parking lots, where stormwater runoff is a concern.

"The engineers at VDOT have definitely done their homework," Kresge said. "It is apparent that they have been paying attention as they’ve attended the numerous pervious concrete seminars hosted by VRMCA and others."

 

The proposed special provision closely mirrors the recommendations of ACI 522.1-13. Kresge did provide some additional input with regard to proposed requirements for density, use of fibers and QC/QA requirements. A spokesperson for VDOT indicated that, while they are finalizing the provision, they are already looking for possible applications. "Once they’ve selected some sites, they’ll be looking to our industry for additional assistance to assure success," Kresge added.
