AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV – 1963. The apparatus used is Cylindrical measure and plunger Compression testing machine IS Sieves of sizes – 12.5mm 10mm and 2.36mm
Oct 03 2019 This cylinder is subjected to compressive stress. Depending on the type of parent rock gives the different crushing value of aggregate as a compressive strength varying from a minimum of about 45 MPa to a maximum of 545 MPa.. It is a fact that parent rock compressive strength does not exactly indicate the strength of aggregate in concrete.
Jan 20 2020 Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt PA mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture step-loading compression tests were conducted on the mixtures of PA-13 and a control asphalt mixture AC
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.
