Abstract

Permeable pavements have been known for allowing infiltration of water, which expedites the removal of surface runoff. Thus, the use of permeable pavements is increasingly becoming popular among road builders, as it alleviates the problem of water ponding on flat roads. Pavement surfaces with ineffective infiltration impedes the removal of surface runoff, which may lead to pavement cracking and deterioration due to water ponding on the pavement. There are several types of permeable pavements available in the market, one being concrete grid pavers (CGP). CGP paving systems consist of concrete blocks with both voids inside and between the blocks. CGP generally has a maximum dimension of 60 mm x 60 mm, and a thickness of 90 mm. Voids range from 20 to 50 percent, while the minimum compressive strength is typically 35 MPa. The void spaces between blocks are commonly filled with top soil and grass, aggregate or sand. In contrast, conventional asphalt pavements consist of about 95 percent stone, gravel and sand by weight, and about 5 percent asphalt cement that acts as a glue to bind the pavement.
