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. The improved dry time coupled with lower environmental liability can provide significant cost savings. |
