Standard Aggregate Crushing Value

Jan 20, 2020 In current Chinese technical specification, the crushing value of the coarse aggregate for surface layer of asphalt pavement is no greater than 26% . 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%
