| Abstract: | This report mainly discussed the performance of modified asphalt and mixture by domestic natural asphalt, and a series of experiments including common performance, track tests and freeze--thaw tests were carried out to evaluate the in- fluence of domestic natural asphalt. The final tests results show that, natural rock asphalt can significantly enhance the degree of asphalt gelation, increase softening point and viscosity, and significantly improve high temperature stability and moisture stability of asphalt mixture. |
