Commonly used for parking lots and other light-duty applications, full-depth porous asphalt pavements are increasingly being used on roadways as part of efforts to mitigate flooding hazards, reduce hardscape, and improve sustainability. To help ensure these new porous asphalt roadways provide reliable performance under traffic, NAPA has published Structural Design Guidelines for Porous Asphalt Pavements.

 

Written by Charles W. Schwartz, Ph.D., and Kevin D. Hall, Ph.D., P.E., with the support of the NAPA–SAPA Pavement Economics Committee's Pavement Design Task Group, Structural Design Guidelines for Porous Asphalt Pavements discusses the structural design procedure for porous asphalt and the required inputs using the AASHTO 93 design method.
