Pervious concrete pavement must perform as both a stormwater management tool and a pavement. While much research has focused on porosity and permeability of pervious concrete, few guidelines exist for structural analysis and design of such pavement. In this paper, an existing pervious concrete pavement was analyzed for stiffness and fatigue by means of Westergaard’s theory of a medium-thick plate on a Winkler foundation. The stiffness evaluation compared the responses of pervious and conventional concrete pavements to falling weight deflectometer stresses and to models created in ISLAB2005. Although pervious concrete had a lower modulus of elasticity than conventional concrete pavement, Westergaard’s model adequately described the behavior of pervious pavements. Additionally, a fatigue analysis of pervious concrete was completed through use of the StreetPave fatigue model.
