Structural Design Guidelines for Porous Asphalt Pavements (July 2018)

Often the design of porous asphalt pavements is focused on how well the pavement will handle water, not traffic. For most parking lots and light-duty surfaces this may be a reasonable approach, but as public agencies look to use full-depth porous asphalt pavements on roadways a traditional structural design methodology is needed. Written by Charles… Continue reading Structural Design Guidelines for Porous Asphalt Pavements (July 2018)
