摘要
某项目路段建成运行九年且位于寿命末期,虽然经过多次病害处理以及日常养护,但养护方案并未从根本上解决路面病害的发生。通过分析路面技术状况指标与病害成因,从而为该路段路面提出合适的病害处治方案。基于路段交通量重载化、施工质量控制、资金预算等因素,最终选取表面层铣刨加铺5cm中粒式SBS改性沥青混凝土作为修复性养护方案。
The road section of a project has been completed and operated for nine years and is at the end of its service life.Although it has been treated for many times and maintained daily,the maintenance scheme has not fundamentally solved the occurrence of pavement diseases.By analyzing the pavement technical condition indicators and disease causes,this paper puts forward an appropriate disease treatment scheme for the pavement of this section.Based on the heavy traffic volume,construction quality control,capital budget and other factors,the surface layer milling and paving 5cm medium grained SBS modified asphalt concrete is finally selected as the restorative maintenance scheme.
