Performance Evaluation of Pervious Pavement Using Accelerated Pavement Testing System
Pervious pavement is gaining popularity in pavement industry because of its extraordinary water permeability, traffic noise reduction, and wet driving safety. However, the larger air voids of pervious pavement bring high susceptibility to damage resulting from environmental and traffic stresses. Therefore, focusing on the service performance of permeable pavement under various moisture and loading conditions is of critical importance. This paper presents a study which aims to investigate the service behavior of water permeable pavement topped with polyurethane-bounded pervious mixtures (PUPM) under various loading and environmental conditions. To achieve this objective, a full-scale test track was constructed in Germany. The performance of pervious pavement test track was evaluated under accelerated loading with three loading speeds at different environmental conditions. During the loading process, vertical total stress of each pavement layer were recorded as the response to hydro-mechanical loading. Analyses show that the response of different pavement layers to hydro-mechanical loading is varied. The water table inside the permeable pavement as well as the water scouring effect on the pavement is affected by the loading speed. Water permeable pavement could be an effective way to help mitigate the heat island effect.
