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 Los Angeles (L.A.) 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.

These differences in aggregate properties were accompanied by differences in bacterial colonization. Also, the additional re-wetting and sonication during wet sieving probably removed bacterial cells, leading to a lower bacterial diversity in the occluded microaggregate fraction compared to the microaggregates obtained upon dry crushing.
