Methods and apparatus for stabilization of surfaces
First Claim
1. A surface composition for application to at least one of a roadway void and a flooring for traffic, the surface composition comprising:
- a liquid binder comprising a polyurethane adapted to cure through an exothermic reaction process, wherein the cured liquid binder has an increased viscosity relative to the liquid binder prior to curing; and
a primer adapted to adhere to the cured liquid binder and the at least one of the roadway void and the flooring;
wherein the surface composition applied to the roadway void and the flooring is adapted to withstand wear from the traffic over the roadway void and the flooring.

Abstract
Various embodiments provide surface compositions and methods for repairing durable and/or load-bearing surfaces including roadway voids, manhole structures, and/or safety flooring. Compositions and methods may comprise utilizing a liquid binder, catalyst, and/or primer to provide durable, waterproof, and/or long-lasting surface compositions to dispose within the roadway voids and/or to coat flooring. The surface compositions may cure rapidly through an internal exothermic reaction process to form the repair and/or the safety flooring. In some embodiments, filler materials may be disposed within the liquid binders to provide elasticity, compression, slip resistance, heat transfer, reduced cure time, and/or a desired surface texture to the surface composition.

11. A method for filling a roadway void comprising a cavity having a surface comprising the steps of:
-
applying a primer to at least a portion of the cavity surface; filling the cavity with an amount of a liquid binder sufficient to be level with the roadway such that the liquid binder is in contact with and adheres to the primer, wherein the liquid binder comprises polyurethane adapted to cure through an exothermic reaction process, and wherein the cured liquid binder has an increased viscosity relative to the liquid binder prior to curing; and allowing a sufficient amount of time for the liquid binder to cure before resuming traffic over the roadway. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for forming a safety flooring over a surface for at least one of human traffic and animal traffic comprising the steps of:
-
mixing a liquid binder with a filler material; applying a mixture of the liquid binder and the filler material over the surface, wherein the liquid binder comprises polyurethane adapted to cure through an exothermic reaction process, and wherein the cured liquid binder has an increased viscosity relative to the liquid binder prior to curing; and allowing a sufficient amount of time for the liquid binder to cure before resuming the at least one of the human traffic and the animal traffic over the surface. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
