半柔性沥青路面与普通沥青路面力学响应分析

Mechanical response analysis of semi-flexible asphalt pavement and common asphalt pavement

半柔性沥青混合料是新型路面材料,兼顾刚性和柔性两种路面的优点,摒弃两者的缺点。研究采用有限元分析,通过弯沉、弯拉应力等指标,对比分析研究半柔性沥青混合料在不同结构层的沥青路面与普通沥青路面对路面结构力学响应的影响,为半柔性沥青路面结构设计、技术推广提供理论依据。

Semi -flexible asphalt mixture is new pavement materials, combines the advantages of rigid and flexible pave- ment, abandon the disadvantages. Study with finite element analysis, through the flexure, flexural - tensile stress indicators, conduct comparative analysis and research on the impact of flexible asphalt mixture and common asphalt mixture in different struc- tural layer on pavement structure mechanics response, provides theory basis for the design and technology promotion of flexible asphalt pavement structure.
