Pervious concrete as a sustainable pavement material - Research findings and future prospects: A state-of-the-art review

In the last few years, the use of pervious concrete as a pavement material in low-volume road applications has gained importance due to its positive environmental aspects. This paper reviews the developments and state-of-the-art pertinent to pervious concrete research and practices. The investigations on mechanical-hydrological-durability properties of pervious concrete performed in various studies have been reviewed. The storm water purification efficiency of pervious concrete has been documented. The field investigations of few test sections and in-service pervious concrete pavements have been discussed. A review has been made on rehabilitation techniques to increase the hydraulic efficiency of pervious concrete pavements. A note has been mentioned on the life cycle cost analysis of pervious concrete. Due to an increased use of pervious concrete in the pavement industry due to its multitudinous benefits, there exists an expansive scope for further research to understand the material better, which will make it a promising sustainable roadway material in future.
