Lab Report.docx  Determination of Aggregate Impact
Objective The objective of this experiment is to determine aggregate impact value of given aggregate sample. Concepts and Significance This experiment is used to measure the Aggregate Impact Value (AIV) of different crush samples. This test is used to determine the relative toughness of aggregates. Toughness of aggregates is the ability of an aggregate to resist impact or sudden shocks.

(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 ...
