摘　　要：为了研究沥青混合料在大温差大风环境下施工温度及其影响因素,根据项目所在地的气候条件确定施工过程中影响混合料温度变化的主要因素。以实体工程为依托,通过比较实测数据与软件模拟施工过程中混合料的温度,分析各种因素对沥青混合料温度的影响规律,得出了大温差大风环境下保证沥青路面压实质量的施工温度测量确定方法。依据工程所在地区气候状况、路面因素及材料情况,得出该施工情况下沥青混合料受环境温度及风速影响下的温降系数,对沥青路面施工温度及质量等实际问题的控制起到指导作用。To investigate the construction temperature and its influencing factors of asphalt mixtures in environments with large temperature differences and strong winds,the main factors affecting the temperature variation of the mixtures during the construction process were determined based on the climatic conditions of the project location.With the support of a physical engineering project,by comparing the measured data with the mixture temperatures simulated during the construction process using software,the influence patterns of various factors on the temperature of asphalt mixtures were analyzed.This led to the determination of a method for measuring and determining the construction temperature to ensure the compaction quality of asphalt pavements in environments with large temperature differences and strong winds.Based on the climatic conditions,pavement factors,and material conditions of the project area,the temperature drop coefficients of asphalt mixtures under the influence of ambient temperature and wind speed in this construction scenario were obtained.This plays a guiding role in controlling practical issues such as the construction temperature and quality of asphalt pavements.
