AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead
May 17, 2019 The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. 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

The objective of this test is to: 1. Determine the aggregate crushing value of coarse aggregate 2. Check the suitability of coarse aggregates to use in different types of road. Apparatus Required for
Read MoreName of the experiment: Aggregate Crushing value test. Objective: 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory: The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing under gradually applied compressive load
Read MoreThe strength of coarse aggregates is determined by aggregates crushing test. The aggregate crushing value test provides a resistance of aggregate to crushing under a gradually applied compressive load. To construct a high quality of pavement, aggregate possessing low aggregate crushing value should be
Read MoreAGGREGATE CRUSHING VALUE TEST 1. Objective: To determine the crushing value of road aggregates. 2. Apparatus/Equipments Required: 1. Steel cylinder of 15.2 cm internal diameter with base plate and plunger. The height of the cylinder may vary from 13 to 14 cm. The thickness of cylinder walls may be 1.6 cm. 2
Read MoreAggregate Crushing Value (ACV) test indicates the resistance to crushing under gradually applied crushing load. It is measured as percentage of aggregates passing through 2.36 mm IS sieve after specimen subjected to a compressive load of 40 tonne at the rate 4 tonne per minute and to the weight of aggregates taken
Read MoreThe aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top
