Abstract: This disclosure describes formulations, systems and methods for coal topping, a term which refers to the application of liquid products to the top of coal loads, such as those in open topped coal hopper railcars as commonly used today to transport coal. Disclosed herein are controlled viscosity fluid formulations suitable for use as a coal topper. The fluids include water as a base solvent, polymer and, optionally, crosslinking agents and plasticizer. The polymer is a water-soluble polymer with reactive groups capable of producing viscosity in the solvent and reacting with crosslinking agents and the plasticizer. The polymer is one capable of manipulation to produce appropriate viscosity levels on a consistent basis. Crosslinking agents consist of chemicals capable of reacting with the reactive polymer to produce complexes that become essentially insoluble on drying. The plasticizer is an agent capable of providing for a dried matrix with flexibility without loss of strength.

Abstract: Embodiments of the present invention are methods and chemical compositions of polymers and crosslinking agents that are particularly suited to aggregate, including soil and other natural aggregates, stabilization via hydraulic application. The present invention is an improvement over existing methods as it provides effective stabilization for longer periods. The compositions, when in an aqueous solution and applied to soil or aggregate surfaces, penetrate the surface polymerize and form a crosslinked polymer film. Individual aggregate particles may bind to the polymer or may be entrapped by the polymer film. In the environment, the film is substantially resistant, in the near term, to biodegradation and natural, physical degradation due to weathering and exposure. The resultant polymer film and aggregate or bonded fiber matrix resists erosion by strong wind and heavy rain but readily allows seeds to germinate and grow.
