摘 要: 通过在沥青路面结构层中埋设温度传感器,对沥青路面结构的温度场变化情况进行了连续的的现场观测,描述了昼夜温差及温度随深度的变化情况,并分析了这些变化对沥青混合料动态模量的影响。阐述了在我国路面结构分析和设计中考虑昼夜温差及温度随深度的变化情况的必要性。 Variation of temperature field in asphalt pavement was continuously observed in field by means of buried temperature sensors in structure layer of asphalt pavement. The change of temperature with depth and diurnal amplitude were described, and also analyzed these changes effect on dynamic modulus of asphalt mixture. Finally the necessity of considering the change of temperature with depth and diurnal amplitude in pavement structure analysis and design was described.
