Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index .
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 ...
Note 1 a procedure for testing coarse aggregate larger than 19.0 mm 3 4 in. is covered in test method c535. thus coarse aggregates with a maximum size between 19 mm 3 4 in. and 37.5 mm 1 1 2 in. may be tested by test method c535 or test method c131c131m.
Bs 812 part 110 describes a method to determine the aggregate crushing value acv which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load.the method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.
Mar 01, 2020nbsp018332the crushing strength or aggregate crushing value of a given road aggregate is found out as per is2386 part
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.
In this paper, the role of crushing operation on the cubical controlling features of coarse aggregates, and its influence on the shape distribution characteristics of aggregates i.e. angularity ...
