高寒地区沥青混凝土路面施工质量控制措施分析——以乌兰巴托新国际机场高速公路项目为例

Analysis on the Quality Control Measures for Asphalt Concrete Pavement Construction in Alpine Regions—Taking the Ulan Bator New International Airport Expressway Project as an Example

高寒地区的沥青混凝土路面施工与普通环境的施工不同,需要考虑海拔、严寒因素,合理选用施工技术,保证面板结构的抗寒性能,提升路面施工质量。基于此,文章以具体工程为例,首先对高寒、大温差气候条件下沥青混凝土路面施工难点及主要病害成因进行分析,随后针对主要病害提出一系列沥青混凝土路面施工技术,以供参考。

The construction of asphalt concrete pavement in alpine region is different from that in ordinary environment.It is necessary to consider the altitude and cold factors,and select the construction technology reasonably to ensure the cold resistance of panel structure and improve the quality of pavement construction.Based on this,taking a specific project as an example,this paper first analyzes the construction difficulties and main disease causes of asphalt concrete pavement under the climatic conditions of alpine and large temperature difference,and then proposes a series of asphalt concrete pavement construction technologies in view of the main diseases for reference.
