Hydrologic performance of permeable pavement systems utilising various sub-base materials for Caribbean applications

Abstract

This paper examined the hydrological performance of three 0.19m2 laboratory-scale permeable pavement rigs with varying sub-base aggregates of basalt, limestone and recycled concrete aggregates. Observed flows from different underdrain offsets were compared with computer simulations from the stormwater management design tool PCSWMM. Statistical analyses showed a high level of accuracy for numerous simulated events. Nash-Sutcliffe and R2 coefficients ranged between 0.85 and 0.99 for all rigs. Root-mean-square-error (RMSE) was generally less than 0.01 for all simulations. During rainfall events, the rigs produced no surface runoff and temporarily detained up to 84 % of rainfall input.
