Abstract

In concrete and asphalt concrete, the shape (roundness) of aggregate particles has been related to durability, workability, shear resistance, tensile strength, stiffness, and fatigue response. The aggregates are constantly subjected to harsh environmental conditions and external forces including static and dynamic loads. As a result, these materials experience various levels of abrasion. Hence, alteration of aggregate roundness with different chemical and mechanical effects is important for engineers. In this research, 40 basalt and calcareous aggregate samples are prepared with different abrasion methods and the roundness of samples is determined using image analysis. As a result, calcareous aggregate is significantly affected from the abrasion methods but basalt aggregate is not.
