ACPA’s PerviousPave is design software that provides results optimized for both structural and stormwater-management requirements by determining:

  1. The required minimum thickness for pervious concrete pavement, based on the design traffic, design life, and other structural inputs, and
  2. The required subbase/reservoir thickness necessary to satisfy stormwater management requirements, based on the volume of water to be processed by the pavement within the required maximum detention time.

PerviousPave is available as a free download and may be used without a license for up-to 30 days. After the 30-day trial period, you will need to purchase a license to continue using your copy of PerviousPave.
