05-05-2010· 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 economical performance.

The results obtained show that ACV value for aggregates are 25.04%, 22.70%, 36.13%,and 37.89% for crushed granite, slag, hoggin (all-in aggregate), and river gravel respectively. This show that the...

It was proposed that the crushing value of the coarse aggregate used in PA mixture should be no more than 20% . Liu et al. suggested that the crushing value of coarse aggregate for the OGFC-13 mixture should not exceed 15% . Dang et al. proposed that the crushing value of coarse aggregate was not more than 15% .

The aggregate crushing value (ACV) obtained is 43.75 which is within the specified value of 45 as specified by the British standard (BS 812-110 1992).

Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100. Lab Report
