ABSTRACT
Pervious pavements are generally weak in material strength and can be easily clogged. Thus, they were normally used for non to light traffic conditions. An innovative eco-technology recently developed in Taiwan uses air-circulated aqueduct frames and impervious Portland cement concrete on top of an aggregate layer to form a structured permeable concrete pavement can alleviate such problems. Through proper designs, this pavement can possess adequate load bearing capacities as conventional concrete pavements do. In an attempt to develop a systematic thickness design approach for JW ecotechnology pavement, the fatigue model and reliability concept of PerviousPave was re-investigated. The PCAWIN software along with the PerviousPave design methogology was adapted into a prototype Eco Pave program. A tentative regression model is created and used in EcoPave program to account for the discrepancy in determining the probability of failure (P). Research efforts are still underway to incorporate the hydrological design methodology of PerviousPave into the EcoPave program.
