Hydraulic Design of Interlocking Concrete Permeable Pavement
Stormwater management and design was developed to reduce the impacts of runoff due to the increase in urbanization and impervious area in the hydrologic system. Stormwater management takes many different forms, including Best Management Practices (BMP). BMPs include both non-structural and structural practices (McCall III, 2014). The focus of this thesis is on the structural BMP, Permeable Interlocking Concrete Pavement (PICP). PICP is a type of pervious pavement that will increase the amount of water infiltrated through joint spacing filled with open graded aggregate above an open-graded base and sub-base, creating a stormwater storage and infiltration (Interlocking Concrete Pavement Institute, 2014). The reduction of runoff from increasing storage and infiltration, also reduces the amount of pollution that would enter nearby water bodies (Environmental Protection Agency, 1999). Laboratory testing was conducted on a PICP section with at a variety of slopes and spacing. The laboratory results are presented in Amanda Leipard’s 2015 Thesis, “Hydraulic Characterization of Permeable Interlocking Concrete Pavement”. The results found the horizontal infiltrate rate for each variation lower than the corresponding vertical infiltration rate. A computational design tool was built for PICP based on relative storm information and site information to determine the hydraulic characteristics the site can attain.
