Abstract: An environmentally friendly composition and related methods of use and production of an asphalt prime coat, suitable for application to a base road structure, are described herein. The composition includes an asphaltine, and an emulsion of a natural hydrocarbon resin mixed with a penetrating component, which can include a very limited quantity an organic solvent, or can omit organic solvents. If organic solvents are omitted, a hydrophobic wax can be added for moisture retention and water impermeability. Dispersion agents can be used to facilitate penetration into the base road. Rheology modifying agents and/or alcohols can be used to add flexibility, decrease curing time, and improve thickness and viscosity. The prime coat contains a lower quantity of volatile organic compounds than conventional prime coats, reducing environmental impact. The drying time of the composition is less than alternative compositions.
