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.
Claims9
Method of resurfacing new or existing surfaces of a highway, road, bridge deck, garage deck, airport ramp, airport runway, driveway or sidewalk to provide a skid-resistant surface comprising the steps of:
- (A) preparing a polymer concrete composition by
- (1) mixing
- (a) 5 to 95 wt. % of a curable polymer composition containing an ethylenically unsaturated polymer containing carbon, hydrogen and oxygen in the polymer molecule and carbon-bonded carboxyl groups in the amount of about 1 to about 3% based on the weight of said curable polymer composition of carbon-bonded hydroxyl groups in the amount of about 0.5 to about 7.5% based on the weight of said curable polymer composition or both in the molecule, and
- (b) at least one reactive 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 said polymer, said Group IIA metal oxide or hydroxide being reactive with said carboxyl groups of said polymer to thicken said polymer composition at a controlled, delayed rate or (2) a polyisocyanate in the amount of 0.1 to 10 equivalents per carbon-bonded hydroxyl group of said polymer, said polyisocyanate being reactive with said hydroxyl groups of said polymer to thicken said polymer composition at a controlled, delayed rate, and
- (2) mixing the resulting mixture of (a) and (b) with (c) 5 to 95 wt. % of an aggregate in which at least 20% of the particles have a minimum dimension of 1/16 or greater before thickening of said polymer composition impedes wetting of said aggregate by said polymer composition to form a slump-resistant, curable polymer concrete composition;
- (B) coating said surface with said slump-resistant, curable polymer concrete composition,
- (C) compacting and shaping said polymer concrete composition on said surface, and
- (D) curing the resulting compacted, shaped polymer concrete composition on said surface.
