Evaluation of polyphenylene sulfide and steel fibers on mechanical properties of pervious concrete pavement

Strength is the primary concern for Portland cement pervious concrete (PCPC) designs. Since PCPC has a high void ratio (often without fine aggregate due to the permeability requirement), compressive and tensile strengths tend to be lower than those of conventional concrete pavements. In this experimental study, PCPC mixes made with steel fibers and polyphenylene sulfide (PPS) fibers and various amounts of sand were evaluated. Mechanical properties, porosity, and permeability of the PCPC were tested. The results pointed out adding fibers to the mixes increased the concrete strength as well as void content. It is noteworthy to mention that PPS fibers performed better than steel fibers. Addition of a small amount of fine sand (approximate 7 % by weight of total aggregate) to the mixes with PPS fibers significantly improved the concrete strength.
