Structural and Hydrological Design of Sustainable Pervious Concrete Pavements

Building on previous advances in thickness design methodologies for jointed plain concrete pavements, a mechanistic design methodology for use in the structural design of pervious concrete pavements is presented. Although most jointed plain concrete pavement structural design methods include both fatigue (e.g., slab cracking) and erosion (e.g., faulting or surface smoothness) as failure criterion, the proposed pervious concrete pavement structural design includes fatigue as the sole failure criteria due to a lack of evidence that erosion occurs on pervious concrete pavements. To ensure both an optimal structural design and that stormwater management requirements are met, a hydrological design method that varies the subbase/reservoir layer thickness to meet hydrological demand also is presented. These structural and hydrological design methodologies have been combined into software called PerviousPave, a user-friendly tool for the design of sustainable pervious concrete pavements. Example program runs are also provided to demonstrate the ease of use of the program and how the user can design their own pervious concrete pavement.
