公路沥青路面同步碎石罩面施工关键技术

The Key Technology of Construction of Synchronous Gravel Cover of Highway Asphalt Pavement

为了探讨公路路面预防性养护施工技术要点及质量控制对策,延长沥青路面使用寿命,以山西省省道S233公路路面养护为背景,通过论证,确立了施工技术方案,并提出同步碎石罩面施工工艺流程及质量控制对策。通过落实同步碎石罩面施工技术措施及施工质量控制对策,S233公路路面病害至今未出现进一步恶化,路面平整度合格率≥90%、弯沉值始终满足车辆安全行驶要求。

In order to discuss the technical points and quality control measures of preventive maintenance of highway pavement,and prolong the service life of asphalt pavement.Based on the background of pavement maintenance of provincial highway S233 in Shanxi Province,the construction technical scheme was established through the scheme demonstration,and the construction process and quality control measures of synchronous crushed stone cover were put forward.Through the implementation of the technical measures for the synchronous gravel cover construction and the construction quality control measures,the quality disease of the S233 highway pavement has not deteriorated further.The qualified rate of pavement flatness is 90%,and the bending value always meet the vehicle safety requirements.
