Asphalt diversity hydrothermal aging test simulation method

The invention discloses an asphalt diversity hydrothermal aging test simulation method. The method comprises the following steps: preparing a specified amount of a sample, and injecting water meetingthe amount into a water holding device of an improved pressure vessel; placing the sample on a test piece rack in a layered manner; closing a valve, and adjusting a test program; and taking out the sample after reaching the test time. According to the test, damp and hot aging in a high-humidity environment are simulated by evaporating a large amount of water to fill the whole accommodating cavity;a rainfall plate system is arranged to simulate water scouring and aging in a rainfall environment; water erosion aging in a water immersion environment is simulated through full-water immersion. According to the diversified hydrothermal aging laboratory acceleration simulation method based on an improved pressure aging container, namely, under the same experiment condition, the experiment requirements of simulating vario
