BS 812-110:1990 Testing aggregates Methods for …

This Part of BS 812 describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.

Explanation: Crushing test: This test is carried out to assess the strength of coarse aggregate when a compressive load is gradually applied.; Aggregate crushing value = (W 2 /W 1) × 100 where, W 1 = Total weight of the dry sample . W 2 = weight of material passing through 2.36 mm IS sieve. The aggregate crushing value for the surface course should be within 30% and …

Crushing strength of road stone may be determine either on aggregates or on cylindrical specimen cut out of rocks. The two tests are quite different not only in the approach but also in the expression of the results. Aggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads.

getting reproducible results. On the contrary, the aggregate crushing test is simple, rapid and gives fairly consistent results. Application of Aggregate Crushing Test: The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low.

Aggregate Crushing Value Test

This test is repeated once or twice and the average crushing value of the aggregate is determined. 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%.
