Jan 20, 2020 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.

Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. 7. 33.
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV 1963.as per is code it should not be more than 25 for wearing surfaces amp 45 for non wearing surfaces.
The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30 or higher, the results are likely to be inaccurate. Aggregate Crushing Load Source The Constructor, Civil Engineering Home
Oct 03, 2019 Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load. Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
May 11, 2020 DETERMINATION OF TEN PERCENT FINES VALUE OF COARSE AGGREGATE. Test standard IS 2386 -Part IV 1963 Purpose of Test Ten percent fines value is a measure of the resistance of aggregate crushing subjected to loading and it is applicable to both weak and strong aggregate.
Aggregate crushing value W2 x 100 W1-W W2 Weight of fraction passing through the appropriate sieve W1-W Weight of surface dry sample. The mean of two result to nearest whole number is the aggregate crushing value. Result The aggregate crushing value of the given sample Aggregate Crushing Values for Roads and Pavement Construction
