Aggregate Impact Value is the resistance of an aggregate to impact stress produced from a moving vehicle. Values of less than 20 are acceptable for highway wearing courses. ACV. =. Aggregate Crushing Value is the resistance of an aggregate to crushing. The lower the ACV, the more resistant the aggregate is to crushing.
It is recommended to use a ... aggregate crushing value, aggregate impact value, and rock properties [45,46,47,48,49,50,51,52]. These studies have shown that if we have one of these values determined by the test, it is possible to estimate another two related values .
The Los Angeles () abrasion test (Figure 1) is a common test method used to indie aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing.
Key points. • 'Aggregate' is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 80% of the concrete mix. They provide compressive strength and bulk to concrete.
