| 摘 要： | 倒装型基层是福建省常用的沥青路面结构型式,其沥青层厚度达26cm。而沥青材料性质对温度敏感,进行温度场分析很有必要。通过有限元仿真分析,对福建省夏季高温时典型日照下倒装沥青路面结构内的温度场进行计算,得到内部各层温度的时空分布,并经过经验公式和相关资料的实际监测验证。结果表明,有限元分析可以作为沥青路面结构设计和沥青材料选择时计算路面温度的快捷可靠的方法。

| Abstract: | Inverted base is a common type of asphalt pavement structure in Fujian Province,with thickness of asphalt layer up to 26 cm.It is necessary to analyze the temperature field for temperature sensitivity of asphalt.Through finite element analysis,the temperature field in the inverted asphalt pavement structure of Fujian Province under the typical sunshine in summer is calculated,and the temporal and spatial distribution of temperature in each layer is obtained,which is verified by the empirical formula and the actual monitoring of relevant data.The results show that the finite element method can be used as a fast and reliable method to calculate the pavement temperature in the structural design of asphalt pavement and the selection of asphalt materials. |
