Abstract: Pervious concrete may be used in road pavements to prevent flash flooding and provide wet-weather skid resistance due to its porous nature. Besides adequate strength, it must possess good clogging and sound absorption characteristics. This study investigated the use of steel fibers in enhancing the flexural strength of pervious concrete without compromising its permeability and porosity. To meet these requirements, the target strength of the pervious concrete was 3.5 MPa and the permeability and porosity were 10 mm/s and 20% or higher respectively. This research has (a) provided a new pervious concrete mix design that meets the target performances of having reasonable flexural strength, permeability and porosity for pavement use, (b) recommended porosity level for good drainage performance with satisfactory clogging resistance and (c) evaluated and compared expected sound absorption properties of the recommended pervious concrete mix design with other existing road materials.
