Abrasion resistance of roller compacted concrete

Abrasion resistance is a fundamental property of concrete when used in pavements, even though it is seldom addressed in job specifications. The paper presents experimental results obtained with a selected standard method (ASTM C 779, Procedure C, Ball Bearings). Concrete mix proportions and the construction technique used for specimen preparation are relative to roller compacted concrete technology. It is found that the adopted testing procedure is simple and reliable. The surface layer of samples reinforced with steel or synthetic fiber does not behave differently from that of plain matrix samples, and poor curing has more impact on quality of the concrete surface than on compressive strength.
