05-05-2010· Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. 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.
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 used in road construction is expressed by numerical index .
11-08-2020· The aggregate whose crushing value is less than 30% can be used for cement concrete road. The aggregate whose crushing value is less than 40% can be used for wearing surface. This test must be done before it comes to road and pavement construction.
12-09-2015· Aggregate impact value = (W1/W2)*100. Aggregates to be used for wearing course, the impact value shouldn’t exceed 30 percent. For bituminous macadam the maximum permissible value is 35 percent. For Water bound macadam base courses the maximum permissible value defined by IRC is 40 percent.

Sampling for Aggregate Crushing Value Test: For the Aggregate crushing value test, an aggregate sample passing through 12.5 mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 ºC to 110 ºC then cooled to room temperature. To fill the cylindrical measure mould about 6.5 kg of a sample of aggregate is sufficient.

This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test. Importance Impact Value Test: Generally, the majority of the aggregate test is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.
Aggregates used in the road construction should have the following properties: a.Strength: The aggregate to be used in road construction should be sufficiently strong to withstand crushing and several stresses due to traffic wheel load.
Aggregate is a collective term for the mineral materials such as gravel, sand and crushed stone, which are used along with binding materials such as bitumen, cement, lime, etc to form compound materials.Properties of aggregate play a vital role in the strength and durability of structures.
Aggregates form the major portion of the pavement structure. Bear stresses occurring on the roads and have to resist wear due to abrasive action of traffic. Aggregates are also used in flexible as well as in rigid pavements. Therefore, the properties of aggregates are of considerable importance to highway. The aggregates to be used in road construction, particularly

The test sample consists of aggregates passing 14 mm and retained on 10 mm sieve. Wash the sample and dry at 100 to 110 °C for four hours and cool to room temperature Fill the cylindrical measure with the aggregate sample and tamp with 25 blows of tamping rod.
Procedure of Aggregate Impact value test. The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled.
The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
