AGGREGATE ABRASION VALUE (AAV) DETERMINATION

The test measures the resistance of aggregates to surface wear by abrasion. Inadequate abrasion of road-surfacing aggregates leads to an early loss of the texture depth required to keep high-speed skidding resistance.
The machine consists of a heavy duty mainframe on adjustable feet, steel lap wheel 615 mm diameter, which rotates in a horizontal plane at 28/31 r.p.m., precision machined steel shaft and sealed bearings, resilient mounted electric gearmotor, scraper blades for sand removal, revolution counter.
The control panel can be wall fixed or placed on a bench.
Supplied complete with two specimen moulds, two trays, weights and fixing device.
