Crushing Strength Test on Aggregates. Aggregate crushing value gives the Crushing strength of aggregate up to which it can bear the load without fail. To conduct crushing strength test we need compression testing machine, cylindrical measure, plunger and Isa sieves.
Sep 24, 2010· The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions (Figure 1). Dry aggregates passing through 12.5 mm sieves and retained 10 mm sieves are filled

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
Jul 16, 2014· Aggregate impact value test also gives an indirect indication of the strength characteristics of aggregate. Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates. It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact
May 03, 2018· 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.
Aggregate crushing value, when determined in accordance with IS: 2386 (Part IV)-1963 shall not exceed 45 % for aggregate used for concrete other than for wearing surfaces, and 30 percent for concrete for wearing surfaces, such as runways, roads
Main Roads are responsible for delivering and management of a safe and efficient main road network in Western Australia. Representing one of the world's most expansive road networks, we are committed to working cooperatively and productively across all levels of government, to ensure our road network meets the needs of the community, industry and stakeholders.
The aggregate crushing value is defin ed as a ratio of the weight, of fines passing the specified sieve (2.36 mm) to the total weight of the sample expressed as a percentage. Aggregate crushing value > 35 weak for pavement Aggregate crushing value < 10 exceptionally strong Rock group Crushing value
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.
The aggregate crushing value is defin ed as a ratio of the weight, of fines passing the specified sieve (2.36 mm) to the total weight of the sample expressed as a percentage. Aggregate crushing value > 35 weak for pavement Aggregate crushing value < 10 exceptionally strong Rock group Crushing value

Aggregate Crushing Value Test Crushing strength of road stones may be determined either on aggregates or on cylinderical specimens However aggregate crushing values have not been specified by the IRC for coarse aggregates to be used in bituminous pavement construction methods. 1. Methods for Sap:tpling and Testing of Mineral Aggregates
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.
Jan 27, 2019· The aggregate crushing value should not be more than 45% for aggregate used for concrete other then the wearing surfaces. 30% for concrete used the surfaces such as runway, roads and air field pavements. Also Read: What is impact value test of aggregate ? References: Aggregate Crushing Value; Aggregate crushing value test
The suitability of aggregate in the pavement layers is dependent upon the type of road construction. The specified limits of aggregate crushing value for different types of road construction are given in the table below. Limits of aggregate crushing value for different types of road construction
Aggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test.
Nov 18, 2019· The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred.
