既有公路技术状况评价及病害处治方案研究

Research on the Technical Condition Evaluation and Disease Treatment Scheme of the Existing Highway

为保证既有公路的行车安全,文章以某高速公路为研究对象,利用自动化+人工的检测方法,从路面破损、平整度、车辙、弯沉等方面对沥青路面技术状况展开评价。同时,阐述了直接灌浆、开槽灌浆、铣刨加铺等方案在沥青路面裂缝病害和车辙病害处治中的应用,研究成果可为类似项目提供参考。

In order to ensure the driving safety of existing highways,this paper takes an expressway as the research object,and uses the automatic+manual detection method to evaluate the technical condition of asphalt pavement from the aspects of pavement damage,flatness,rutting and deflection.At the same time,the application of direct grouting,slotting grouting,milling and paving schemes in the treatment of asphalt pavement crack disease and rutting disease is expounded.The research results can provide reference for similar projects.
