Specified limits of percent aggregate crushing value for different types of road construction s given bellow.
2. Aggregate crushing value . 45 for aggregates used for concrete for non wearing surfaces and 25 for wearing surfaces like runways and roadways. Discussion Determination of Aggregate Crushing Value Density Crushing value is defined as the ratio of finess passing a standard sieve produced by crushing under standard condition to the.
Aggregate Crushing Value Conclusion. The Aggregate Crushing Value (ACV) Test Set measures how resistant an aggregate is, when being crushed under a gradually applied compressive load. Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod.
The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.
“Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load” In situations, when aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined and used instead.
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 surface dry sample.

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 13, respectively.
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.
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.
May 22, 2020 The aggregate crushing value= B A 100 . Where, B is weight of fraction passing 2.36mm sieve A is weight of surface dry sample taken in mould. Note. The aggregate crushing value should not be than 45 for aggregate used for concrete other than the wearing surfaces. 30 for concrete used the surfaces such as runway, roads and air field.
The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample is subjected to a specified load under standard conditions.
