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.
the mobile stone crushing station can process the materials on the site, and the material will not be removed from the site for reprocessing, which greatly reduces the transportation cost of the material. 4. Direct effectively homework. The integration of the series stone crushing and screening plant can be used independently. Read More
Aggregate impact value, AIV, aggregate crushing value, ACV, and 10 per cent fines loads, however, are aggregate size dependent. Tests on larger aggregate sizes give higher test values, whereas tests on smaller aggregate sizes give lower values than test results for standard size aggregates.
Abstract Preview. This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve. For other size
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%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for
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. The crushing value of aggregate = (W2/W1) x 100. Lab Report

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.
Calculation of Aggregate Crushing Value: Aggregate crushing value can be found by the following formula, “Aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 2.36 mm IS Sieve divided by weight of aggregate sample taken for test” Aggregate crushing value = (W3 W) or W3 (W2 W1)
May 27, 2020· 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 12.5mm IS sieve and retained on 10 mm IS sieve. Procedure. About 6.5 Kg material consisting of aggregates passing 12.5mm IS sieve and retained on 10mm sieve is
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
Aggregate impact value, AIV, aggregate crushing value, ACV, and 10 per cent fines loads, however, are aggregate size dependent. Tests on larger aggregate sizes give higher test values, whereas tests on smaller aggregate sizes give lower values than test results for standard size aggregates.
Aggregate Impact Values, (AIV’s), below 10 are regarded as strong, and AIV’s above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Aggregate Impact Value; Test Specifications:
