Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

More2021-7-21 The crushing value of the coarse aggregate is defined as the relative measure of the resistance which is offered by the aggregate to the crushing under the gradually applied load. #2 Impact value of Aggregate ( IS 2386 Part IV -1963)

More2017-5-29 The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS

More2020-1-20 The crushing of coarse aggregate in PA mixture is caused by the excessive contact pressure between aggregates, so the coarse aggregates are more easily crushed by vehicle load. So, the crushing value of coarse aggregate is very important for the durability of PA mixture [1–3].

More2016-12-15 Aggregate Crushing Value (ACV) is one of the important properties of coarse aggregate. ACV gives a relative measure of resistance to crushing under gradually applied compressive load. Thus ACV is inversely related to strength of coarse aggregate. In concrete pavement design ACV of coarse aggregate is given much importance.
