Abstract
A wear surface such as steel bridge deck surfaced with a wear-resistant overlay such as plastic tiles is disclosed in which the tiles are bonded to the deck by means of a bonding layer having preferably a shore 00 hardness of from approximately 78 to 90 and comprising an elastomer compounded with a stiffening filler in an amount equal to at least about half the weight of the elastomer. Low volatile liquid plasticizer is present in an amount to provide the stated hardness. The elastomer is preferably a mixture of acrylic elastomer and butyl elastomers, and the stiffening filler is a high abrasion furnace carbon black. The tiles are adhered to the layer with a solution coating comprising neoprene in admixture with a terpene-phenolic resin and the coating desirably includes a hydrophobic silica.
