摘要
针对沥青路面冻融受荷损伤问题,推导了冻融受耦合损伤本构关系,建立了冻融与荷载耦合作用下沥青混合料损伤演化方程,指出冻融损伤累积和荷载作用产生的应力集中加剧了总损伤劣化程度。
In light of asphalt pavement freezing-thawing loading damage problems,the paper induces constitutive relationship of freezing-thawing coupling damage,establishes asphalt mixture evolution equation,and points out that： freezing-thawing accumulation and loading stress aggravate total damage degradation degree.
