Abstract

The focus of this paper is on the use of porous recycled inclusions in portland cement concrete (PCC) pavements. Described is the methodology that breaks down the concrete into its major components of air voids, aggregate, and cement paste. The three methods that have been used to reduce the noise on PCC pavements are: control of the source of noise; shielding the noise generated; and reduce the noise by controlling the noise propagation. The results demonstrate that porous PCC pavements work by controlling noise propagation.
