The aggregate crushing value test (ACV, BS 812-Part-110) is one of the test methods for determining the crushing resistance of the aggregates. Alvarado et al. [ 4 ] and Reyes et al. [ 5 ] concluded that the ACV test was practical, reproducible, and stable and is a pivotal method in the evaluation of aggregate crushing resistance.
