Abstract: Composition produced from paving grade asphalt, process oil (not over 32%) and SBR rubber or rubbers, such as butadiene-styrene copolymers, in decreasing amounts by weight. A preferred range is asphalt 41.9-61.25%, process oil 18-25%, lower molecular weight butadiene-styrene copolymer 8-17%, higher molecular weight butadiene-styrene copolymer 2-4% and filler, such as limestone dust, 0-20%. Other preferred formulae are shown, as well as temperature and other conditions of the preferred method, including reheating of composition for application to joints, cracks and the like.

Abstract: A concrete cure is provided which is totally water based and completely void of solvents. A moisture impermeable film is attained when the cure is applied to fresh concrete. The cure forms a barrier over the concrete allowing it to retain over 95% of the mixing water for a minimum of 72 hours when applied at the rate of 200 ft.sup.2 /gallon (5m.sup.2 /dm.sup.3). The concrete cure of the invention is a mixture of a hydrocarbon resin, emulsifying agents, paraffinic wax, and water. The cure may be provided in a clear or pigmented formulation. A method for making the concrete cure is also disclosed.
