ABSTRACT:
A road construction material includes a hydrocarbon-laden mixture of fine aggregates and a hydrocarbon solvent, the hydrocarbon-laden fine aggregate mixture having a hydrocarbon content in a range of approximately five to twenty percent by weight and the hydrocarbon content including at least approximately 50 percent by weight light end crudes, the road composition material being made by cold-blending the hydrocarbon-laden fine aggregate mixture and the hydrocarbon solvent and marinating for a time sufficient to diffuse the hydrocarbon contents of the hydrocarbon-laden fine aggregates with the hydrocarbon solvent. There may also be added a light weight ceramic aggregate mixture for additional strength and stability. Heat stabilzing, anti-stripping agents and anti-track compounds may be added as desired.
