如何设计更加科学合理的公路路面,不断提高路面的使用性能和耐久性一直是技术人员研究的主要课题。文章通过对河北省高速公路沥青路面技术发展历程和实践经验的总结,探讨了沥青路面技术方面存在的一些问题。然后,基于国内外沥青路面技术研究的成果,提出适应河北省交通环境的合理沥青路面结构形式,其实用性较强,也为其他省份沥青路面结构的设计与施工提供了较为有价值的参考。
How to design a more scientific and rational road pavement and continuously improve the serviceability and durability of the pavement have been the major topics that the technicians study. The paper summarizes the development history and practical experience of asphalt pavement technology in Hebei Province Expressway, and discusses some problems in the technology of asphalt pavement. Then, based on the results of the research on asphalt pavement technology both at home and abroad, this paper proposes a reasonable asphalt pavement structure adapted to the traffic environment of Hebei Province. The practicality is strong, which also provides a valuable reference for the design and construction of asphalt pavement structure in other provinces.
