摘要
为减少沥青路面的不平整度,提升路面结构承载性能与行车舒适性,开展低噪声柔性加固基层沥青路面结构设计研究.首先,根据设计目标和工程需求,确定合理的级配范围;其次,基于路面结构层厚度力学分析结果,设计路面结构层厚度;最后,利用低噪声柔性加固基层技术设计沥青路面的各个层次结构.应用分析结果表明,应用文章提出的设计方法后,路面平整度均方差始终较低,可以有效改善沥青路面的平整度,保证路面性能与行车舒适性.
Abstract
In order to reduce the unevenness of asphalt pavement, improve the load-bearing performance and driving comfort of the pavement structure, this article conducts research on the design of low noise flexible reinforcement base asphalt pavement structure. Firstly, determine a reasonable grading range based on design objectives and engineering requirements; Secondly, based on the mechanical analysis results of the thickness of the pavement structural layer, design the thickness of the pavement structural layer; Finally, use low noise flexible reinforcement technology to design the various hierarchical structures of asphalt pavement. The application analysis results show that after applying the proposed design method, the mean square error of road surface smoothness is always low, which can effectively improve the smoothness of asphalt pavement, ensure road performance and driving comfort.
