Jan 20, 2020So, the crushing value of coarse aggregate is very important for the durability of PA mixture [ 1 3 ]. Yan et al. proposed that the requirement for the crushing value should be no more than 20% [ 4 ]. Huang proposed that the crushing value of coarse aggregates for OGFC mixture should be no more than 25% [ 5 ].

ContactCoarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.
