No.8 Aggregate Impact Value Test

The strength of coarse aggregates is assessed by aggregates impact test. The aggregate impact value provides are lative measure of resistance tocrushing under a gradually applied compressive load. To achieve a high quality of pavement, lower aggregate impact value should be preferred. Toughness is the property of a material to resistimpact.
