Assessing the abrasion resistance of cores in virgin and recycled aggregate pervious concrete

Abrasion resistance of pervious concrete was evaluated on core and cast specimens by using the Rotating-Cutter method and the Impact Abrasion method. Sixteen mixtures were produced using limestone, pea gravel, and recycled concrete aggregate, and up to 30% of cement was replaced by ground granulated blast-furnace slag. The analysis of the core specimens indicated that the Impact Abrasion method had a low within-test coefficient of variation and was able to differentiate among mixtures. The use of recycled aggregate and ground granulated blast-furnace slag did not have a detrimental effect on the abrasion resistance of pervious concrete.
