Tenth International Conference on The Constructed Environment

Abstract

Pervious concrete (PC) is specified by its characteristic of allowing water to flow through the depth of the concrete layer. Parking areas may utilize this material to rejuvenate the top layer of the pavement by helping stormwater runoff vertically pass through the PC into the underneath layers of the pavement. This study focuses on maximizing the sustainability through the use of waste-stream materials and elevating the environmental impacts of using pervious concretes by replacing raw materials with wholly recycled materials. This study provides a comparison between compressive strength and porosity of PC made form virgin raw materials and that made from recycled materials. Specifically, three mixtures are tested that include 100% portland cement and natural stone, 100% blast furnace slag and recycled concrete aggregate, and a 50% combination mixture. Porosity and compressive strength tests are conducted for the hardened pervious concrete. The hydraulic conductivity and strength development for the PC mixtures are evaluated to study the effect recycled materials has on the properties of pervious concrete used for parking lots. Lastly, the measured properties of the recycled PC are then utilized in the design of a parking lot located on the campus at the University of Georgia.
