· The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS2386 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.
The aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available: 150 (standard) and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure.
Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (WaWe) W2= Weigh of aggregates passing through IS sieve.
Aggregate crushing value significance test procedure the crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the is sieve mm 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.
· The crushing value of an aggregate indicates its resistance against crushing under gradually applied compressive loads. The standard aggregate crushing test is made on aggregate passing IS sieve and retained on 10 mm IS sieve. Procedure. About Kg material consisting of aggregates passing IS sieve and retained on 10mm sieve is ...

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
Aggregate Crushing Value Test Determine Aggregate ... 201055 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.
Los Angeles abrasion test on aggregates is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is carried out by AASHTO T 96 or ASTM C 131: Resistance to Degradation of SmallSize Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine. The aggregate used in surface course [.]

The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. All parts directly coming in to contact with the specimen during the test are made of mild steel duly case hardened.
Aggregate Crushing Value Test Civiconcepts. Aggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing mm and retained on 10 mm sieve.
Determination Of Aggregate Crushing Value Test Mongolia. the ucs ranges from 95mpa to 169mpa while the schmidt rebound number ranges from 29to 35 comparing the los angeles abrasion, impact and crushing value obtained from the laboratory destructive test with the bstandards, most of the rock can be used for construction works.
the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a mm test sieve and retained on a mm test sieve. For other size fractions, there is another recommended method.
