Abstract: A slump-resistant, curable polymer concrete composition, suitable for coating onto a concrete surface or an asphalt surface to resurface same, comprising (a) 5 to 95 weight percent of an aggregate at least 20 percent of which has a minimum particle dimension of 1/16 inch or greater, (b) 5 to 95 weight percent of a curable polymer composition containing an ethylenically unsaturated polymer containing carbon, hydrogen and oxygen in the molecule and carbon-bonded carboxyl groups or carbon-bonded hydroxyl groups or both in the molecule, (c) an effective amount of a curing catalyst effective to initiate the curing of the polymer, and (d) at least one reactive, time-delay thickener comprising (1) a Group IIA metal oxide or hydroxide in the amount of 0.1 to 20 equivalents per carbon-bonded carboxyl group of the polymer, the Group IIA metal oxide or hydroxide being reactive with the carboxyl groups of the polymer to thicken said polymer concrete composition and/or (2) a polyisocyanate in the amount of 0.

Abstract: Resurfacing surfaces of highways, roads, etc. to provide skid-resistant surface by preparing polymer concrete composition containing a curable polymer composition containing ethylenically unsaturated polymer having carbon-bonded carboxyl groups and/or hydroxyl groups and at least one reactive thickener comprising Group IIA metal oxide or hydroxide or a polyisocyanate; mixing the resulting mixture with aggregate; coating said surface with the resulting composition; compacting and shaping the resulting composition and curing the compacted, shaped composition on said surface.
