(DOC) AGGREGATE IMPACT VALUE TEST | hong g.woei

The aggregate impact value provides a relative measure of resistance to crushing 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 resist impact. Due to traffic loads, the aggregate are subjected to the pounding action
