In this test, the aggregate's resistance is determined to crushing under gradually applied compressive load. a) IS codes for Crushing value Test: IS 2386(Part 4):1963
The code suggests the determination of these values for which you need to refer IS 2386 - part 1. While sourcing the aggregates, one must also look for the mechanical properties to ensure the strength and durability requirement of the aggregates. The code suggests the following tests: Aggregate crushing value; Aggregate impact value
Roundness can be tested using the shape test, crushing by crushing test and durability by soundness test. 2. If the aggregate impact value lies between 10 – 20%, the aggregate is said to be ______
This test, prescribed by BS 812: Part 110:1990, assesses the resistance of an aggregate to crushing, indicating its ability to withstand compressive loads.

This test is conducted to determine the crushing strength of aggregate. This test helps to assess the suitability of aggregates for use in road construction and other applications where they are subjected to high compressive stresses. The specifications for this test are given in IS : 2386 Part IV 1963 mechanical properties. Procedure

The test sample shall be subjected to a total of 15
The test conducted to know the compressive strength of aggregate is known as aggregates crushing value test. 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 ...

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. 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.
The values of aggregate crushing test agree in general with that of aggregate impact test. The crushing strength test is most significant as far as the conditions to which the aggregates is likely to be subjected in practice are concerned. The suitability of aggregate in the pavement layers is dependent upon the type of road construction.
