8. Recommended Crushing Value Standard of Coarse Aggregate in PA Mixture. In current Chinese technical specification, the crushing value of the coarse aggregate for surface layer of asphalt pavement is no greater than26%. So, the crushing value standard of basalt coarse aggregate used in PA mixture should be increased to not more than 26%/1.48 = 17.6%
