Abstract: As a non-ignorable environmental factor in the service process of asphalt pavement, the temperature has attracted extensive attention at home and abroad. Temperature change can cause different temperature stresses to occur inside the pavement structure. In order to master its main research methods and current situation, it was analyzed from three aspects such theoretical analysis, numerical simulation and experimental research. The application scenarios and limitations of different methods were systematically summarized, providing reference for further improvement of research methods. The research results show that the viscoelasticity, stress history and relaxation effect of materials are successively considered in the theoretical analysis method, and the research tends to be gradually improved. Judycki analysis method considers the rheological and viscoelastic properties of materials, which is more in line with the actual stress characteristics of pavement than Monismith analysis method and Hills & Brien analysis method. However, due to some assumptions in the theoretical analysis, there is a deviation between the thermal stress prediction model and the actual value. So, the follow-up research can start with the material characteristics of asphalt mixture, considering the viscoelastic characteristics, to improve the theoretical model and the application scope and accuracy of the theoretical formula. Secondly, the numerical simulation method can scientifically and efficiently study the influence law of different stress states, parameter values and environmental factors on the service performance of asphalt pavement, but the rationality of the model depends on the selection of material parameters. So, the follow-up research should take the scientific definition and comprehensive acquisition of material parameters as the starting point. Finally, the indoor experiment TSRST has high international recognition and is often used as a measurement standard of whether the analytical method is reasonable or not. And the full-scale pavement test loop is more scientific than the indoor test, which has the convenience of space, technology and time. It is the most effective method to study the actual response of pavement structure. The analysis of full-scale loop data may become a follow-up research hotspot.

摘要： 温度作为沥青路面服役过程中不可忽略的环境因素，已受到了国内外的广泛关注。温度变化会导致路面结构内部产生不同的温度应力，为掌握其主要研究方法及现状，从理论解析、数值模拟及试验研究三方面展开分析，系统总结了不同方法的应用场景及局限性，为后续完善研究方法提供参考。研究结果表明：理论解析法中先后考虑了材料黏弹性、应力历史和松弛效应，研究趋于逐渐完善，其中Judycki解析方法考虑了材料流变特性及黏弹特性，较Monismith解析方法、Hills & Brien解析方法更符合路面实际受力特性，但由于理论解析均存在部分假定，使得温度应力预估模型与实际数值存在偏差，后续研究可从沥青混合料材料特性入手，如考虑材料黏弹特性、完善理论模型、提高理论公式的使用范围及精度等；数值模拟法可以科学高效研究不同应力状态、参数取值及环境因素对沥青路面服役性能的影响规律，但模型的合理性依赖于材料参数的选取，后续研究应以科学定义、全面获取材料参数为切入点；室内试验TSRST的国际承认度高，常被用作解析方法合理与否的衡量标准，足尺路面试验环道较室内试验更科学，具有空间便利性、技术便利性及时间便利性，是进行路面结构实际响应研究最有效的方法，针对足尺路面试验环道数据的分析或将成为后续研究热点。
