- Abstract:
-
In order to forecast the time regularity of the asphalt thermal and oxygen aging,the RTFOT experi-ment was applied,according to the principle of evaluating system stability with the variable tendency of itscompatibility,the destabilization of asphalt aging was predicted with the grey-cusp-catastrophic destabilizationprediction model. The research results show that the catastrophe exits in the aging process, and hysteresis phe-nomenon exits between catastrophe and aging actions. For the asphalt mixture,the heating time should not ex-ceed 50 min, and to make the asphalt pavement have the long services life,the measures should be taken toextend the catastrophic happened time.
