关于沥青路面在低温时初始开裂的思考

摘要

针对沥青混凝土路面低温开裂进行了分析,阐述了开裂机理,通过建立模拟路面在寒潮时的受力状况的简化模型,分析了初始裂缝产生原因,并对路面抗裂措施提出建议,以期指导实践。%The paper analyzes the low temperature cracks of asphalt concrete pavement,illustrates the crack mechanism,establishes the simplified model for simulation pavement under stress in cold wave,analyzes the reasons for the initial cracks,and points out the suggestions for the pavement anti-crack measures,so as to direct the practice.
