Abstract

In order to make clear the research status of long-life asphalt pavement in China and abroad, this paper summarized the development characteristics, pavement structure, design index, pavement material, dynamic response analysis of pavement, fatigue performance estimation, and other hot issues of long-life asphalt pavement, compared the structural characteristics of long-life asphalt pavement in various countries, and summarized the results of pavement material design and optimization. The research progress of the dynamic response of asphalt pavement was summarized, and the development direction of long-life asphalt pavement was discussed. The comprehensive analysis shows that long-life asphalt pavement is the development trend of asphalt pavement in the future. At present, there are still some shortcomings in the research on long-life asphalt pavement, such as the lack of a unified design index, poor accuracy of mechanical response prediction model, and weak pertinence of structure and material design. Further research is needed from the aspects of solid engineering analysis and verification, mechanical response prediction model modification, structure and material multi-scale genomic analysis, etc.
