Abstract
A method of fabricating a substantially rigid hardened wear surface for a tire tread wear testing apparatus is provided, the method comprising making a cast of a road surface on which tread wear of the tire is to be tested, providing a layer of adhesive mixed with at least one aggregate and configured for hardening to create the substantially rigid hardened wear surface, while the layer of adhesive is unhardened: (a) coating the layer of adhesive onto a road wheel of the tire tread wear testing apparatus, and (b) stamping an impression of the cast into the layer of epoxy adhesive for producing the wear surface adapted for emulating one or more surface roughness characteristics of the road surface.
