国道213线郎木寺至川主寺路段(郎川段)地处高寒湿地,其独特的气候特点和自然环境特征致使其热拌沥青混合料路面的施工中遇到的问题和质量控制措施与规范中的规定不尽相同。笔者从该路所处环境气候条件出发对本路地处3500～3800m路段气候进行了观测,在施工过程中根据气温、下卧层温度、风速和气温的升降提出了普通沥青路面和改性沥青路面施工温度控制、碾压长度控制和铺筑时间控制要求,以保证路面的铺筑质量。
State Road 213 Langmusi to Chuanzhusi section (Langchuan section) is located in the alpine wetlands, its unique climate characteristics and natural environment characteristics of the hot asphalt mixture pavement problems encountered in the construction and quality control measures and norms The provisions in the different. Based on the climatic and climatic conditions of the road, the author observed the climate of this section located in the 3500 ~ 3800m section. During construction, normal asphalt pavement and modified asphalt pavement were proposed according to the temperature, the temperature of the subsoil, the wind speed and the temperature rise and fall Temperature control, rolling length control and paving time control requirements, in order to ensure the pavement pavement quality.
