ENGINEERED SURFACES FOR LABORATORY TREAD WEAR TESTING OF TIRES

摘要

A substantially rigid hardened wear surface (104) for testing tread wear of a tire (106) comprises an adhesive mixed with at least one aggregate and configured for being hardened and imprinted with a cast of a road surface on which tread wear of the tire (106) is to be tested. The adhesive is coated onto a road wheel (102) of a tread wear testing apparatus (100) and imprinted with the cast of the road surface when the adhesive is unhardened, the wear surface (104) adapted for emulating one or more surface roughness characteristics of the road surface.
