摘　　要：路面结构在自然环境中经受着持续变化的各种环境因素影响,这种影响主要体现为路面温度场的复杂分布,温度对沥青路面的承裁能力和使用性能都有显著影响。文章结合青海德大公路工程,对其路面温度场数据进行采集与分析,系统地研究了路面结构在不同季节的温度场变化规律,提出了路面结构层深度方向温度场日变化的4种趋势。Pavement structure subjected to various environmental factors. The effect was mainly reflected as the complicated distribution of pavement temperature field. The load-bearing capacity and performance of the asphalt pavement was affected significantly by temperature. Based on temperature field data acquisition and analysis,this paper systematically studied variation of temperature field of pavement structure in different seasons,and proposed four trends of diurnal variation of pavement temperature field with depth.
