Chapter4 testing on aggregate 4.1 aggregate crushing value test 4.1.1 aim the aim of that test is to determine the aggregate crushing value of coarse aggregate which is passed from 12.5mm is sieve and retained on a10mm. 4.1.2 apparatus a steel cylinder of 15mm diameter with base plate and plunger a straight metal taping rod 16mm diameter and 45 to 60cm long rounded at one end.
Aggregate crushing value test apparatus is used for measuring resistance of an aggregate to crushing. made of mild steel comprising of 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, tamping rod, 16mm dia x 450 to 600mm length.
Aggregate crushing value indicates strong aggregates, as the crushed fraction is low. hus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components. the aggregates used for the surface course of

The 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. 3. apparatus
Aggregate impact values, aivs, below 10 are regarded as strong, and aivs 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
Number. report the mean as the aggregate crushing value, unless the individual results differ by more than 0.07 times the mean value. in this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the aggregate crushing value. a data sheet is given as form 7.7.1.
This situation is where choosing between a loader or an excavator to feed aggregate can be an influential factor in your crushing operation. with a loader, it can be difficult to gauge the size of aggregate in the bucket whereas using an excavator can help control the
Aggregate impact and crushing test linkedin slideshare. feb 08, 2012183 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.
