Laboratory and Field Evaluations of Pervious Concrete

This study evaluates the factors affecting the testing of strength and hydraulic parameters of pervious concrete pavement (PCP), presents results of long-term infiltration monitoring and cleaning operations, and investigates freeze-thaw durability of pervious concrete and the effects of fly ash. The specific objectives of this study were to: (1) determine how rubber capping and sulfur capping affect compressive strength measurements of PCP; (2) determine the effects of height to diameter (H:D) ratio of cylindrical specimens on compressive strength measurements of PCP; (3) compare various methods used to determine infiltration rate of PCP in the field to one another and to laboratory measurements of hydraulic conductivity; (4) monitor two PCP facilities in Vermont for changes to infiltration rate over time; (5) evaluate the effects of various cleaning methods on the restoration of infiltration rates; (6) determine the effects of deicing salts on pervious concrete, using a modified and more field representative testing procedure that involves slow freeze-thaw cycling in drained condition, and (7) determine the effects of cement replacement with increasing amounts of fly ash on the freeze-thaw durability of pervious concrete. In addition, the results of this study were used to suggest correlations to the field observations seen at several pervious concrete sites in Vermont.
