基于建养一体化的高速公路拼宽改建段路面设计方法研究OA
Research on Pavement Design Method of Highway Widening Reconstruction Section Based on Integration of Construction and Maintenance
通过对我国华南地区高速公路拼宽改建段路面病害类型及形成原因的深入分析,选择了裂缝率、车辙深度和平整度指数作为拼宽改建段控制路面服务性能的设计指标,针对各指标建立了相应的分析和预测模型,提出了基于建养一体化的拼宽改建段路面设计指标;结合环境参数、交通量、材料参数、分析期等因素以及基于建养一体化的效益费用分析计算,形成了基于建养一体化的高速公路拼宽段路面设计方法及流程.采用该方法对广东省某高速公路改扩建项目的拼宽改建段路面结构进行设计,结果显示,通车…查看全部>>
The types and causes of pavement diseases in the highway widening reconstruction section in South China were in-depth analyzed in this paper.The crack rate,rut depth and roughness index were selected as the design in-dexes to control the pavement service performance.The corresponding analysis and prediction models were estab-lished for each index,and the pavement design indexes were proposed based on the integration of construction and maintenance.Combined w…查看全部>>
