The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. . The specific gravity of aggregates normally used in road construction ranges from about 2.5 to 2.9. Water absorption values ranges from 0.1 to about 2.0 percent for aggregates normally used in road surfacing.

The aggregates crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. the aggregates used in road construction must be strong enough to withstand crushing under traffic.

Aggregate crushing Value =(WB/WA) × 100 REPORT The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. Specified limits of percent aggregate crushing value for different types of road construction s given bellow.

The aggregates crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. the aggregates used in road construction must be strong enough to withstand crushing under traffic.

The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions (Figure 1 ).

Impact, 10% Fines & Crushing TestsQuarry plant such as crushers, screens, conveyors, etc. are all subject to wearand these crushing tests can indicate the magnitude of the problem for designpurposes.PROCEDURE – Aggregate Impact Value (SS 1974)1.

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.
