2013-12-1The strength and stiffness of CCA with a maximum particle sie D max 37.5 mm obtained from a typical concrete crushing plant are noticeably lower than CCA sieved to D max 19 mm compacted using the same energy. However when compacted to the same dry density the original CCA exhibits the strength and stiffness higher than the sieved CCA
Investigation of Coarse Aggregate Strength for Use in Stone Matrix . specified a maximum Los Angeles Abrasion loss value of 30 percent. compaction was the most accurate method for predicting coarse aggregate performance of the four tests. TRB Subject Code 35-1 Aggregate Characteristics and Tests. . procedure of crushing test for testing of
Aggregate used in road construction should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test
