Abstract: A coating system and related methods for an airfield surface or a roadway is described. The coating system may include a stable cationic emulsion for application to the airfield surface or the roadway. The stable cationic emulsion may include a) an asphalt blend comprising gilsonite, wherein the gilsonite is modified to possess a positive charge, b) one or more polymers, and c) one or more surfactants not including a cationic surfactant. The coating system may also include a fine aggregate material for application to the stable cationic emulsion applied to the airfield surface or the roadway.
Abstract: The present disclosure includes systems and methods for applying a coating system to a surface. An example method includes spraying an asphalt emulsion onto a surface at a rate of between about 0.12 and 0.20 gallons per square yard, the asphalt emulsion having: an asphalt blend comprising gilsonite, wherein at least a portion of the gilsonite is modified to possess a positive charge; one or more polymers, and one or more surfactants. The method may include applying a fine aggregate onto the asphalt emulsion. The fine aggregate may be applied at a rate of 2.5 pounds per square yard. In such an aspect, the asphalt emulsion may be sprayed at a rate of about 0.18 gallons per square yard, and the asphalt emulsion may contain about 56% solid asphalt residues by weight of the asphalt emulsion. In another aspect the fine aggregate may be applied at a rate of about 1.25 pounds per square yard, the asphalt emulsion may be sprayed at a rate of about 0.
