Procedure to determine Aggregate Crushing Value i The aggregates passing through 125mm and retained on 10mm IS Sieve are ovendried at a temperature of 100 to 110 o C for 3 to 4hrs ii The cylinder of the apparatus is filled in 3 layers each layer tamped with 25 strokes of a tamping rod iii The weight of aggregates is measured Weight 'A' 1. Introduction. So, the crushing .
Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surfacedry sample
· The aggregate crushing value test indies the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength low crushing value should be preferred. .
· The aggregate crushing value test evaluates the ability of the aggregates used in road or pavement construction to withstand the stresses induced by moving vehicles in the form of crushing. With this, the aggregates should also provide sufficient resistance to crushing under the roller during construction work and under rigid tyre rims of heavily loaded animals or men drawn vehicles.

PREPARATION OF TEST SPECIMENS As described in SABS Method 841 except that at least three test specimene (each of mass about 3 kg) are required for each test (wet and dry). SECTION 3. .
· 1 To determine the aggregate crushing value of coarse aggregates 2 To assess suitability of aggregates for use in different types of road pavement 2. PRINCIPLE 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 . Aggregate crushing value test outline. .
· Aggregates used in the construction, should be strong enough to resist crushing. If the aggregates are weak, the stability of the structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied .
· Abrasion Value. Coarse aggregate should be hard enough to resist abrasion. This decreases the chance of wear and tear in concrete. i. Crushing Value. The crushing value gives the resistance of a coarse aggregate to crushing under the appliion of compressive load. j. Deleterious Materials. Coarse aggregate should be free from deleterious materials such as clay, silt, dust, salt .
To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, steploading compression tests were conducted on the mixtures of .
Aggregate Crushing Value Civil Engineering. This test helps to determine the aggregate crushing value of coarse aggregates as per IS: ... please how can i .
· 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, steploading compression tests were conducted on the mixtures of PA13 and a control asphalt mixture AC13, respectively.
· Aggregates used in the construction, should be strong enough to resist crushing. If the aggregates are weak, the stability of the structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied compressive.
