1. 0 objective to determine the aggregate crushing value (acv) by compressive testing machine.. 2.0 introduction the aggregate crushing value is the value which is mostly used in the design of the pavement of the road because it gives the crushing strength of the aggregate. other than aggregate crushing value there are other parameter required in the design and these include; the elongation.aggregate crushing value test lab report,aggregate crushing value test lab report pdf. 2017-12-30sieve analysis of fine and coarse aggregates txdot designation tex-200-f construction division 5 10 effective date january 2016 7rocedure 7prepare the material sample in accordance with section 3ote 3test a minimum of two samples from each stockpile when developing a mixture design in accordance with tex-204-fweigh the total..aggregate crushing value test 10 fines value test,mechanical properties of aggregates aggregate crushing value test (bs:812, part 3) procedure the material to be tested should pass a 14.0 mm (1/2 in.) sieve and be retained on a 10 mm (3/8 in.) sieve. dry the sample in an oven at 100-110 0 c for four hours. place the sample in a standard cylindrical mould and tamp it. put a plunger on the top of the aggregate and place the
theory: the aggregate crushing value give a relative measure of the resistance of an aggregate to crushing under gradually applied compressive load. its the percentage by weight of the crushed(finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and is a numerical index of the strength of the aggregate used in road construction..aggregate crushing strength test,the crushing strength or aggregate crushing value of a given road aggregate is found out as per is-2386 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.
calculation of aggregate crushing value. the aggregate crushing value is defined as the ratio of the weight of fines passing through specified is (here 2.36mm sieve) to the total weight of sample expressed in percentage. w1= weigh of the total aggregates (wa-we) w2= weigh of aggregates passing through 2.36mm is sieve..aggregate impact value report,aggregate impact and crushing test - slideshare. feb 08, 2012 the aggregate impact value (aiv) is b aiv = 100 () . . . (1) aresultsan average is taken of the two tests and the result is recorded to the nearestwhole number as the aggregate impact value.the aiv is normally about 105 per cent of the aggregate crushing value and itcan be used for the same purpose..aggregate crushing value test procedure civil4m,the aggregate crushing value is an indirect measure of crushing strength of the aggregates. low aggregate crushing value indicates strong aggregates, as the crushed fraction is low. thus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components.
aggregate crushing value test apparatus is used for measuring the resistance of an aggregate to crushing. made of mild steel. cylindrical cell, 150mm internal dia x 130 to 140mm height. plunger, 148mm dia x 100 to 115mm height. base plate, 200 to 230mm square x 6mm thickness..aggregate crushing value test step by step procedure,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
