Oct 12, 2015 The test measures the resistance of aggregate to wear due to attrition between rock particles and also to impact and crushing by steel spheres (Kahraman and Fener 2007). Aggregate crushing value (ACV) and aggregate impact value (AIV) are two well-known British tests for assessing the degradation of aggregate. ACV gives a relative measure of the ...
