The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. 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

Chapter-4 Testing On Aggregate 4.1 Aggregate crushing value test 4.1.1 Aim The aim of that Test is to determine the aggregate crushing value of coarse aggregate which is passed from 12.5mm IS sieve and retained on a10mm. 4.1.2 Apparatus A steel cylinder of 15mm diameter with base plate and plunger A
Aggregate Crushing Value Test - Significance Test ... 2021-9-19 The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1.
Aggregate Impact Value Test Procedure Uses. 2021-6-12 The aggregate impact value test will be conducted as per the Indian Standard Code IS code 2386 Part 4. Conclusion. Average of Impact Value of Aggregate 16.5%. Now the tested aggregates are passed to be used in construction work.
Apr 07, 2020 Aggregate crusing value (A.C.V.) To test the crushing value of Aggergate we use a sample of Aggregate which passes through 12.5mm sieve and retained on 10 mm sieve. To test the Aggregate crushing we uses a mould i.e cylinder to fill with Aggregate having dimension of diameter 25mm and height 25mm. After filling mould a total load of 40 tone is ...
Procedure of Aggregate Impact Test. The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110 C for a period of 4 hours and cooled. (i) Sieve the material through 12.5 mm and 10.0mm IS sieves. The aggregates passing through 12.5mm sieve and retained on 10.0mm sieve comprises the test material.
Calculation of Aggregate Crushing Value. The ratio of weight of fines formed to the weight of total sample in each test shall be expressed as a percentage, the result being recorded to the first decimal place. Aggregate crushing value (W2 x 100) / (W1-W) W2 Weight of fraction passing through the appropriate sieve. W1-W Weight of surface dry sample.
Aggregate crushing value (W2 x 100) / (W1-W) W2 Weight of fraction passing through the appropriate sieve W1-W Weight of surface dry sample. The mean of two result to nearest whole number is the aggregate crushing value. Result The aggregate crushing value of the given sample Aggregate Crushing Values for Roads and Pavement Construction
Aug 27, 2019 Discussions and Conclusions. The values of aggregate crushing test agree in general with that of aggregate impact test. The crushing strength test is most significant as far as the conditions to which the aggregates is likely to be subjected in practice are concerned. The suitability of aggregate in the pavement layers is dependent upon the ...
Accelerated testing at the 2000 NCAT Test Track indicates no difference in the rutting performance of coarse-graded ver- sus fine-graded Superpave mixtures. 6.4 AGGREGATE PRODUCTION Following are the conclusions reached regarding source properties In addition to crusher type, aggregate particle shape can be improved by Running the ...
AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.
This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%.

Procedure. Step 1 First, the aggregate sample sieve through 12.5mm sieve and collect it which is retained in 10 mm sieve. Step 2 Now, the sample should be dried through the oven up to 4 hours at 100 deg to 110 deg. Step 3 Then, the aggregate sample should be filled in the metal cup by 3 layers. Each layer should be tamped 25 times by the tamping rod.
Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. The percentage wear of the sample aggregates due to rubbing with steel balls is determined and is known as Los Angeles Abrasion Value.

Mar 14, 2020 The aggregate with lower crushing value indicate a lower crushed fraction under load and would give a longer service life to the road. Weaker aggregate would get crushed under traffic load. It is clearly seen from Table- that plastic-coated aggregates shows the lower crushing value and which can be withstand to traffic load more efficiently ...
The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source IS 2386 (Part 4)1963)
