基于组合原理的高速公路沥青路面使用性能评价

Evaluation of Asphalt Pavement Performance in Expressway Based on Combination Theory

路面使用性能的评价和预测是路面管理系统的重要环节,对合理地确定养护措施,制定养护方案,安排养护费用起着重要作用。本文在讨论常用综合评价模型的基础之上,提出了三种以改进指标为基准的、以高速公路养护为目的的回归模型,从不同的思维方式去模拟专家的评分过程,最后通过组合原理,建立起以灰色关联度确定权重的综合评价模型。并应用实例验证了本章所给出的沥青路面使用性能综合评价模型作为我国高等级沥青路面养护维修标准的可行性。

The pavement performance evaluation and prediction is an important link in the pavement management system.It plays a significant role in reasonably deciding maintenance and rehabilitation strategies as well as formulating maintenance project and arranging the maintenance costs.On the basis of discussing usual integrative evaluation model and from a different thinking mode in imitating professors＇grading process,this essay puts forward three regression models with improving targets as the benchmark and expressway maintenance as the aim.In the end,an integrated evaluation mode which uses the degree of grey incidence to decide the proportion is presented by using the combination theory.Serving as our country＇s high-grade asphalt pavement＇maintenance and rehabilitation standard,the integrative evaluation model of asphalt pavement performance＇s feasibility is proved by applying living examples.
