高速公路路面养护费用模型的研究

Research on the model for asphalt pavement maintenance of freeway

将高速公路路况综合评价指标Ｒ 与养护费用相联系，通过对大量典型路段的统计分析，找出了高速公路综合路况水平与养护费用的相关关系，建立了基于路况综合评价的养护费用模型，为高速公路的养护管理、养护对策的优先排序提供了一个简捷的参考方法．

This paper presents the relativity between asphalt pavement status and maintenance cost,establishes maintenance cost model by statistic analysis for typical pavements and the relation of comprehensive evaluation parameter R to the cost of maintenance,which provides a method for the maintenance management and maintenance policy.
