| Abstract: | Based on the analysis on the experience of semi-rigid base course asphalt pavement in Liaoning Province and domestic and international long-life pavement design theory,a structure combination of long-life pavement based on combined type base course is recommended.The structural analysis model is established with the finite element method,taking a variety of materials parameters and indicators into account and the recommended combined type structure is analyzed mechanically.Based on the finite element results,the thickness of the combined type structure is put forward. |
