Crushing test One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS:2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.

The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm

The Los Angeles (L.A.) abrasion test is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA.

This test helps in determining the value which indicates the ability of an aggregate to resist crushing. The lower the figure the stronger the aggregate, i.e. the greater its ability to resist crushing.

Determination of Aggregate Impact Value – Impact Test on Aggregates is done to carry out to: Determine the impact value of the road aggregates, Assess their suitability in road construction on the basis of impact value.

Aggregate Impact Values, (AIV's), below 10 are regarded as strong, and AIV's 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:
