The Influence of Extraction Methods on Asphalt Aging Degree Evaluation

Based on the different aging degree of asphalt and the use of inside trichloroethylene dissolved, then use rotation of vacuum recovery instrument recycling asphalt for system test, acquire the performance variation of different aging degree of asphalt between before the recovery and the after. Research results show that the rotation of asphalt recycling vacuum recovery instrument for the aging degree of asphalt have l less influence to the asphalt aging degree, so by rotating the vacuum can be recycled asphalt recycling asphalt instrument to evaluate the degree of aging.
