Water is one of the main factors that influence asphalt aging on long-term use of the process of asphalt pavement.In order to study the impacts of the water work phase and the amount of water on performances of the rubber asphalt aging,taking rubber asphalt and TOR rubber asphalt for example,the influence of different water aging methods on softening point,viscosity,fatigue factor,creep stiffness and creep rate was studied through changing the water work phase and the amount of water.The test results showed that the way of the pressure aging with water for the beginning one third of standard time (400 min) and the pressure aging without water for the remaining two thirds of the time was selected for the most feasible.Comparison of pressure aging test and water pressure aging test,the existence of water can promote the thermal oxygen aging of rubber asphalt.With the increase of water,high temperature stability of TOR rubber asphalt is declined,anti-fatigue cracking performance and low temperature performance of TOR rubber asphalt is declined and asphalt aging intensifies.
