Investigation into the Structural Performance of Pervious Concrete

Abstract

To expand the applications of pervious concrete, additional research and testing must be conducted as to its structural performance. Distress surveys were performed on two field installations of pervious concrete subjected to equivalent traffic stresses as some collector streets in use for 20 years. The results of the distress survey were then used to calculate the pavement condition index (PCI) using the procedure from ASTM D6433. The PCI rating was considered to be a quantification of structural performance. The high PCI ratings of the thicker pervious concrete sections indicated that pervious concrete, when properly designed, is capable of being used for most residential streets and many collector streets for typical design life durations (20–30 years) while exhibiting satisfactory structural performance.
