京港澳国家主干线高速公路湖南潭耒段,自建成通车以来,承担了非常繁重的交通流量,且过往车辆的超载、重载现象非常突出,导致路面结构的承载能力和使用性能受到了较严重的影响,维修的频率较高。该文结合潭耒高速公路提质改造工程项目,对现有路面的损坏状况、承载能力进行详细的调查,在分析的基础上进行评价,初步确定了旧路面改造的压浆控制标准。 Since the completion of its opening to traffic in Hunan Province, the main arterial highway in Beijing, Hong Kong and Macao, Hunan Province, has undertaken very heavy traffic flow. Overloading and overloading of passing vehicles have become prominent, resulting in more severe carrying and using of pavement structures The impact of the higher maintenance frequency. Based on the analysis of the existing conditions of damage and carrying capacity of the existing pavement, this paper combined with the quality improvement project of Tanba Expressway, and preliminarily determined the standard of grouting control of the old pavement reconstruction.
