高速公路沥青路面养护与维修方案的选择与设计

Maintenance and Rehabilitation Strategy Development and Selection for Asphalt Pavements of Expressway

描述系统化的高速公路沥青路面养护与维修方案选择和设计的过程和方法,包括数据的需求采集、现有路况的定性定量评价、养护措施的选择、可行养护与维修方案的生成和设计、备选方案的评估等。由于高速公路具有交通量大、社会影响大的特点,文中重点提出在选择维修方案过程中,需预先分析与不同维修方案相关的交通控制策略及施工规划组织,以对不同可行方案进行全面的评估,从中选取最佳的维修养护方案。

A systematic maintenance and rehabilitation strategy selection and design procedure of asphalt pavements of expressway was put forward in this paper.The framework of this process includes data collection,existing pavement condition evaluation,maintenance and rehabilitation(M&R) treatments selection,M&R strategy development and design,alternatives evaluation,and at last optimum strategy selection.Expressway is quite different from others due to its high traffic volumes and significant impact to the public.Therefore the analysis of traffic and construction issues pertinent to different pavement treatments is emphasized in the process of M&R strategy selection.
