Abstract
The accelerated loading test is more and more favored by researchers because it can obtain the change trend of pavement structure and material performance in a relatively short period of time. This paper first introduces the experimental scheme adopted in this accelerated loading test. The dynamic response under specific parameters is obtained by constructing the field test road and embedding sensors in the pavement structure. Second, according to the measured data, the typical three-dimensional mechanical responses of different layers of asphalt pavement, base and subbase are compared and analyzed respectively, and effective conclusions are obtained. These conclusions can be used as reference for pavement design and maintenance.
