Analysis of Measured Mechanical Response Law of Asphalt Pavement on Roller Compacted Concrete Base Based on Strain Sensor System

[摘要] In order to grasp the measured mechanical response law of the asphalt pavement structure on the Roller Compacted Concrete (RCC) base, taking the asphalt pavement structure of the roller compacted concrete base in the durability test road of Yunluo expressway in Guangdong Province as an example, firstly, the strain sensor layout principle of the asphalt pavement structure was determined and the relevant test plan was formulated with FWD as the loading tool. Then, according to the test scheme, the measured strain response law of the asphalt pavement structure was obtained. At the same time, the theoretical analysis of the same structure was carried out by using ANSYS finite element analysis software. The results confirmed that the theoretical and practical analysis results were in good agreement. The mastery of the measured strain curve law would provide useful help for the design, construction and maintenance of this kind of asphalt pavement in the future.
