一种基于组合式基层的长寿命路面结构设计

Structure Design of Long-life Pavement Based on Combined Type Base Course

在分析辽宁省半刚性基层沥青路面使用经验和国内外长寿命路面设计理论的基础上,推荐一种基于组合式基层的长寿命路面结构组合形式。利用有限元法建立结构分析模型,考虑了多种材料参数与指标条件,对推荐的组合式结构进行了力学分析,基于有限元计算结果,给出了组合结构的厚度。

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.
