Aggregate Impact Value test

A modified Impact test is also often carried out in the case of soft aggregates to find the wet Impact value after soaking the test sample. Lower the aggregate crushing value greater will be the “resistance to to sudden shock or impact (toughness)”.

Pavement materials: Aggregates IIT Bombay

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 ).

Los Angeles Abrasion Pavement Interactive

The Los Angeles () abrasion test (Figure 1) 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.
