Abstract

The invention discloses an asphalt mixture aging test method. The method comprises the steps that: a short-term aging hot-mixed asphalt mixture sample is obtained with a hot-mixed asphalt mixture accelerated-aging method specified by highway engineering asphalt and asphalt mixture testing procedures; the short-term aging hot-mixed asphalt mixture sample is obtained, and a testing method and testing equipments same as those of a pressure-aging-vessel-accelerated asphalt aging test specified by the highway engineering asphalt and asphalt mixture testing procedures are adopted, and an asphalt mixture long-term aging test is carried out; the performances of the long-term aging hot-mixed asphalt mixture obtained by the test is compared with the performances of an original non-aged asphalt mixture, such that the aging degree of the hot-mixed asphalt mixture can be accurately determined. With the testing method provided by the invention, the performance aging condition of the asphalt mixture after long term use in an actual environment can be simulated, such that the aging performance or the anti-aging ability of the asphalt mixture can be accurately determined.

Description

Technical field

[0001] The present invention is a method of aging testing of asphalt mixture. It is to obtain the accelerated aging hot mixing mixture under the high temperature conditions of forced ventilation, which can effectively evaluate the aging performance of the hot mixing asphalt mixture.Technical field. Background technique

[0002] The factors that affect the aging of asphalt are mainly thermal, oxygen, light, and water. Different influencing factors are separate or interactive, changing the formalities and structural links of asphalt, and change the nature of asphalt.

[0003] The method of rapid aging of asphalt in the room has matured. The purpose is to simulate the conditions of the live aging, accelerate the process of asphalt aging, and test the changes in the nature of asphalt at different use stages.And instruct the asphalt's route.However, the aging of the asphalt is not exactly the same as its aging state in the asphalt mixture. In the asphalt mixture, aspha...
