Objective 1 Determine the aggregate crushing value of coarse aggregate 2 Assess suitability of coarse aggregates for use in different types of road Theory The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing under.The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load For achieving a high quality of pavement aggregate of higher crushing strength i e low.
Calculation of Crushing Value Test of Aggregate Crushing strength of aggregate 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”.To Determine Crushing Strength Of Coarse Aggregate Aggregate Crushing Strength Test Online Civilforum Nov 16 2020 The aggregate crushing value of the coarse aggregates used for cement concrete pavement at surface should not exceed 30 and aggregates used for concrete other than for wearing surfaces shall not exceed 45 as specified by Indian Standard IS and Indian Road Congress.
Aggregate used in road construction should be strong enough to resist crushing under traffic wheel loads If the aggregates are weak the stability of the pavement structure is likely to be adversely affected The strength of coarse aggregates is assessed by aggregate crushing test.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 3 APPARATUS The apparatus of the aggregate crushing value test.
Feb 08 2012 Aggregates used in road construction should be strong enough to resist crushing under traffic wheel jloads If the aggregates are weak the stability of the pavement structure is likely to be adversely affected The strength of coarse aggregates is assessed by aggregates crushing test The aggregate crushing valueprovider a relative measure of.The results of tests showed that using of recycled coarse aggregate as alternative to natural coarse aggregate gives good quality concrete and a compressive strength higher than the compressive.
Oct 01 2016 The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads Also read Crushing Value Test of Aggregates 13 Impact Value The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact.Coarse aggregate There are several reasons for specifying grading limits and nominal maximum aggregate size they affect relative 82 Design and Control of Concrete Mixtures EB001 Fig 5 4 Range of particle sizes found in aggregate for use in concrete (8985) Fig 5 5 Making a sieve analysis test of coarse aggregate in a laboratory (30175.
Significance of Aggregate Crushing Value Test The crushing value test is conducted on aggregates that are used for the construction of roads Lower crushing value aggregates give much durability for roads due to its lower crushed fraction under the compression load.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.
