提高沥青路面施工质量是道路界一直关注的重要焦点。研究表明,施工质量的提高除了采用新的材料、先进的机械设备外,控制沥青路面离析对提高沥青路面施工质量也有着十分重要的意义。结合广乐高速公路的施工实践和调查成果,本文对沥青路面离析的种类及进行了系统的梳理,对离析产生的原因进行了详细剖析。同时,从设备、材料、施工等方面提出了沥青路面离析的有效防治措施,这些方法可为高速公路沥青路面施工的质量控制提供指导和借鉴。
Improving the quality of asphalt pavement construction has been an important focus of the road industry. The research shows that besides improving the construction quality by using new materials and advanced machinery and equipment, controlling asphalt pavement segregation is of great significance to improving the quality of asphalt pavement construction. Combined with the construction practice and survey results of Guangle Expressway, this paper systematically sorts off the types of asphalt pavement and systematically analyzes the causes of segregation. At the same time, the effective prevention and control measures of asphalt pavement segregation are put forward from the aspects of equipment, material and construction, etc. These methods can provide guidance and reference for the quality control of asphalt pavement construction of expressway.
