本文通过对不同级配形式的沥青混合料的系统试验研究，全面分析了沥青混合料高温变形特性。根据弹性理论及材料特性提出了高等级道路沥青路面车辙预估方法，计算表明，其结果精度较高。同时，在有效温度计算中，合理地应用了试验研究成果，保证了有关参数的可靠性。 In this paper, different gradation forms of asphalt mixture system experiments, a comprehensive analysis of the asphalt mixture high temperature deformation characteristics. According to the theory of elastic and material properties, the method of rut prediction for high grade road asphalt pavement is proposed. The calculation shows that the result is accurate. At the same time, in the calculation of the effective temperature, the experimental research results are rationally applied to ensure the reliability of the relevant parameters.
