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.

fixing device.
