May 05, 2010· Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more,Aggregate crushing value test  Step by Step Procedure,,The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for,Standard of Crushing Value of Coarse Aggregates for,,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 than 26% . So, the crushing value standard of basalt coarse aggregate used in PA mixture should be increased to not more than 26%/1,
