This paper presents the results of studies conducted to develop a self-consolidating Portland Cement Pervious Concrete (PCPC) for overlay applications to reduce roadway noise, reduce splash and spray, and to improve friction as a surface wearing course. A variety of mixture variables were characterized for workability to develop a mixture for mechanized placement. During the fall of 2008, a 100 mm (4 in.) thick pervious concrete overlay on traditional concrete was constructed at a test facility. Construction is described as well as results of field tests to characterize the condition of the pavement seven months following construction. Performance testing of the overlay section included bond strength, permeability, skid resistance, and noise generation. The results of these studies show that effective PCPC overlays can be designed for wearing course applications.
