基于层次分析法的路面维修方案选择研究

Research on Pavement Maintenance Scheme Selection Based on Analytic Hierarchy Process

为优化路面维修方案的选择方法,结合工程实例,基于旧路路面病害调查和分析结果,采用层次分析法对路面使用性能进行评价,结果表明SSI、RQI、PCI和SFC相应的权重值分别为0.42、0.15、0.27和0.16。基于该结果,采用冷拌再生技术方案对原路段进行处理,采用BISAR软件对维修方案拉应力进行验算,结果均符合要求。

In order to further optimize the road maintenance program selection method, based on the investigation and analysis of pavement diseases in old roads, the analytic hierarchy process （ AHP） method was employed to evaluate the performance of pavement and the results showed that the corresponding weights for SSI, RQI, PCI, and SFC are 0.42,0.15,0. 27 and 0. 16 respectively. Based on the result, the original road section is treated by the cold - mix regeneration technology scheme. In addition, the BISAR software was used to check the tensile stress of maintenance program and the findings showed that this designed pavement structure is practicable.
