Abrasion Machine

AGGREGATE ABRASION VALUE (AAV) DETERMINATION

The test gives a measure of the resistance of aggregates to surface wear by abrasion.
Inadequate abrasion of road-surfacing aggregates means an early loss of the texture depth required to maintain high-speed skidding resistance.

The machine consists of a heavy duty mainframe on adjustable feet, steel lap wheel 615 mm diameter, that 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.

Supplied complete with two specimen moulds, two trays, weights, fixing device.
Power supply: 230 V 1ph 50/60 Hz

Dimensions: 1130x710x1100 mm
