live chatMay 07 32 Objective For determination of the aggregate impact value of coarse aggregate which passes 125 mm IS sieve and retained on 10 mm IS sieve Reference Standards IS Part IV Methods of test for aggregate for concrete Part IV Mechanical Properti Equipment Apparatus Aggregate Impact Test Machine Sieves 125mm 10mm Cylindrical metal measure Tamping Rod
live chatFeb 03 32 So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load The aggregate are mild tough to have the resistance pressure under traffic wheel loads such as
live chatSep 05 32 Aggregate crushing value = B/A x 100 The result should be recorded to the first decimal place and the mean of the two results reported APPLICATION/LIMITS OF AGGREGATE CRUSHING VALUE The aggregate crushing value for cement concrete pavement shall not exceed 30 The aggregate crushing value for wearing surfaces shall not exceed 45 PURPOSE
live chatThe aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance particularly when lower strength is suspected
live chatOverview The Los Angeles LA abrasion test Figure 1 is a common test method used to indicate aggregate toughness and abrasion characteristics Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing degradation and disintegration in order to produce a high quality HMA Figure 1 LA abrasion testing equipment
live chatAggregate 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 surfac Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar and indicate similar aggregate strength properti Aggregate Impact Value Test Specifications
live chatThe Aggregate Crushing Value ACV Test Set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Each set consists of steel cylinder plunger base plate cylindrical measure and tamping rod
live chatIS 4 Methods of test for aggregates for concrete Part 4 IS Z Rules for Rounding Off Numerical Values Revised The number of aggregate crushing value gives a
live chatThe 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
live chatThe apparatus used for determining aggregate impact value of coarse aggregates is Impact testing machine conforming to IS Part IV IS Sieves of sizes 125mm 10mm and 236mm A cylindrical metal measure of 75mm dia and 50mm depth A tamping rod of 10mm circular cross section and 230mm length rounded at one end and Oven
live chatThe 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 measure of the strength of the aggregate The aggregates should therefore have minimum crushing value
live chatThe aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS here 236mm sieve to the total weight of sample expressed in percentage W1= Weigh of the total aggregates Wa We W2= Weigh of aggregates passing through 236mm IS sieve
live chatThe aggregate crushing value ACV of an aggregate is the mass of material expressed as a percentage of the test sample which is crushed finer than a 2 36 mm sieve when a sample of aggregate passing the 13 2 mm and retained on the 9 50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN 2 APPARATUS 21 An
