Abstract: A study to achieve high-strength, high porosity and permeability pervious concrete pavement was carried out. First, the mix proportion in terms of cement content and coarse aggregate-cement (CA/C) ratio and water-cement (W/C) ratio were varied. Next, a mix proportion providing the optimal combination of strength and porosity was chosen, and polymer superplasticizers and short discrete fibers were added to examine their effect on the strength and porosity. Results showed that a water-cement ratio of 0.2 resulted in a dry and brittle mix that led to compressive strength less than 15 MPa but a high permeability rate of approximately 20mm/s. A mix with CA/C ratio of 4.25 resulted in a compressive strength of 13.9 MPa, flexural strength of 3MPa and high porosity of more than 20%. Using comb polymer superplasticier and 2% steel fibers resulted in a compressive strength of 25.1 MPa and a flexural strength of 3.6 MPa at 28 days without compromising on the porosity. © (2013) Trans Tech Publications, Switzerland.
