Based on theory of dissolution and dispersion and special chemical structure of vegetable oil, the article chooses four kinds of vegetable oil (Tung oil, Castor oil, Rapeseed oil and Linseed oil) and blended them with asphalt. And then Rejuvenating Agents of asphalt based on the four kinds of vegetable oil are prepared. The test results show that good exponent relationship is presented between Tung oil content and Brookfield viscosity of Tung-oil-based Rejuvenating Agent. Furthermore, this paper studies the performance of recycled asphalt by conventional indexes, adhesion, SHRP indexes. The data show it by improving the composition of aging asphalt, thereby enabling recycled asphalt indexes recovered to close to or above the level of original asphalt.
