Abstract:

Formulations and methods of making and using two emulsions, one emulsion having a rejuvenating agent and another emulsion having an asphalt phase. The two emulsions may be serially applied or blended together to form a dual emulsion for various deteriorated pavement surface treatments. The two emulsions may be used with a recycled asphalt product, either being mixed with the recycled asphalt product or serially applied to the recycled asphalt product. The two emulsions when blended together may form a dispersion having different phases with different setting times. The surfactant in the rejuvenating emulsion may be faster setting for a preferred initial break and better interaction with the pavement product, while the surfactant in the asphalt emulsion may break more slowly and provide more time to combine with the rejuvenated binder and fully coat the deteriorated asphalt product, and any virgin aggregate added to the mix.
