Abstract: A method of manufacturing an asphalt mix comprising: heating aggregate; introducing RAP to the aggregate; dry mixing the RAP and aggregate; forming a coating of AC on all aggregate during the step of dry mixing by extending the length in time of the dry mixing step; separately blending AC, biodegradable solvents, and anti-stripping agent to produce a blend; and wet mixing the blend into the RAP and aggregate mix. The biodegradable solvents are capable of making the asphalt mix workable at ambient temperatures and comprise pine extract and biodiesel. The length of the dry mixing is extended to at least about 35 seconds. The aggregate comprises coarse and fine virgin aggregate. RAP is about 40% of the final product. The asphalt mix is stockpiled and bagged. The method further comprises manipulating encrusted material on the outside of the stockpiled cold asphalt mix back into the stockpile.

Abstract: An asphalt mix comprising a pine extract, the asphalt mix having low viscosity at ambient temperatures, and workable at ambient temperatures. The asphalt mix comprises asphalt cement, biodiesel, pine extract and an anti-stripping agent. The asphalt mix is an environmentally safe and “green” product. It comprises recycled asphalt product. The asphalt mix eliminates petroleum solvents beyond trace amounts used to denature biodiesel. The asphalt mix is used for patching at ambient temperatures. Safety precautions for heat and toxicity are not necessary for use. The asphalt mix comprises only solvents that are biodegradable. The biodegradable solvents are pine extract and biodiesel.
