7 Lab Test on Aggregate Should Satisfy for Use in
The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low

Crushed Stone
Even with application of gravel as aggregate and lower-strength-class cement [CEM II B/M (PS) 32.5 R], it is still possible to obtain a mixture that meets the strength criteria [28]. In mixes with slag aggregate, there are increases in compressive and indirect tensile strength in mixes with 2% cement content.

Frontiers | Performance Assessment of Ultra-High Durability
A trend of higher strength for the R-UHDC mixes is consistently observed with an increase in compressive strength with the recycled aggregate in particular even for larger percentage substitution of the natural aggregate. This can be attributed to the increased presence of un-reacted cement particles in the finer portion of the recycled aggregate.
