May 08, 2013 Aggregate crushing Value =(W B W A) 100 Record. The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. Safety Precautions Use hand gloves while removing containers from oven after switching off the oven. To wear safety shoes helmet during the time of test.Aggregate Crushing Value (ACV) of the coarse rubber tyres is 0.02, and Aggregate Impact Value (AIV) is 0.004. BS 812 112 1990 stated that if the AIV is than 30 , the results should be treated with caution. Also, According to IS 2386 (Part IV) 1963, if the Aggregate Crushing Value (ACV) is than 30 , aggregates.
The crushing value test of aggregate provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on a 10 mm sieve.Jan 04, 2014 Test Name Methods for determination of Aggregate Crushing Value (ACV) Code BS 812 Part 110, IS 2386. Definition of ACV Aggregate Crushing Value (ACV) gives an relative measure how the aggregate act under an gradually acting compressive load. Sieve Size ACV is applicable for aggregates passing 14.0 mm sieve and retained on 10.00 mm sieve. For other size fractions methods.
Determination of aggregate impact value (AIV) of given aggregate sample (BS 812) Significance Aggregates used in the construction of roads should be strong enough to resist crushing under traffic wheel loads. It gives relative measure of the resistance of an aggregate to sudden shock or impact.This Part of BS 812 describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a 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.
Nigerian the aggregate impact value (AIV) and aggregate crushing value (ACV) are used in scrutinizing aggregates to determine their suitability for use in road constructional work. The ACV test which is prescribed for strong and hard aggregates according to the BS 812, part 110(1990) is a relative measure of the resistance of.Standards. BS 812 110, 812 111. General Description. The Aggregate Crushing Value (ACV) Set (Dia 75 mm) provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Used for the 9.52 mm particle sizes aggregates. AG1120 set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod.
This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test. Importance of Impact Value Test Generally, the majority of the aggregate test is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.Standards. BS 812 110, 812 111. General Description. The Aggregate Crushing Value (ACV) Set (Dia 150 mm) provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Used for the range 12.7 mm to 9.52 mm particle aggregates . AG1110 set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod.

(BS 812) Scope significance Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive 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.For the BS 812 112 method, a small portion of 14–10 mm sized coarse aggregate particles is confined in a steel pot and subjected to 15 blows by a small hammer in a standardised test rig, after which the ‘ aggregate impact value’ (AIV) is determined from the fine material generated, expressed as a percentage of the original weight of the.
The aggregate crushing value is an essential index in the construction of road bases and is defined as the mass percentage of fine particles after a confined compression test of recycled CDW.This Part of BS 812 describes methods for the determination of the aggregate impact value (AIV) which gives a relative measure of the resistance of an aggregate to sudden shock or impact.
