摘　　要：为了研究温拌沥青混合料在低温环境下施工影响因素和施工温度,依据沥青路面热传递模型,确定了施工过程中影响混合料温度变化的主要因素。采用软件模拟施工过程混合料温度变化,分析了各因素对沥青混合料温度变化的影响,得出了低温环境下保证沥青路面压实质量的施工温度确定方法。根据项目所在地纬度、气候状况、路面因素和材料等条件,通过计算得到了温拌沥青混合料在低温环境中的混合料温度与环境温度、风速等参数之间关系。In order to study the influence factors and construction temperature of warm asphalt mixture under low temperature environment, according to the asphalt pavement heat transfer model, the main factors that affect the temperature change of mixture in the construction process are determined. The influence of various factors on the temperature change of asphalt mixture is analyzed by using software to simulate the temperature change of asphalt mixture during construction. The method of determining the construction temperature to ensure the compaction quality of asphalt pavement under low temperature environment is obtained. According to the latitude, climate, pavement structure and materials of project location, the relationship between the temperature of asphalt mixture and the ambient temperature, wind speed and other parameters in the low temperature environment is obtained by calculation.
