高等级公路复合式路面养护标准

针对目前复合式路面养护评定存在的问题,以河南省郑新（郑州—新郑）高速公路为依托,引入Spearman等级相关系数,综合考虑主、客观影响因素,采用了多属性决策组合赋权方法,根据复合式路面结构特点和相关的养护规范与标准,确定了复合式路面养护质量评定指标权重值,通过主、客观养护质量指数对比,建立了二者回归关系式,从而提出了复合式路面养护质量评定标准。最后对复合式路面单项养护维修技术标准进行了分析,并给出了评价实例。结果表明,该养护标准具有较强的客观性和实用性。

Maintenance standards of composite pavement on high-level highway

Taking the Zhengzhou Xinzheng highway of Henan Province as an example, the problems of the present composite pavement maintenance evaluation was analyzed, the Spearman rank correlation coefFicient were introduced, the multiple attribute declsion-making method was developed with the influence of the subjective and obiective factors. According to the structure characteristic of the composite pavement and the correlative maintenance standard, the weight values of the maintenance quality evaluation indices were proposed. Through the contrast of the subjective and objective maintenance quality indices, the regression equation was established, thus the composite pavement maintenance quality evaluation standards were proposed, the single item maintenance technical standards were analyzed, and an evaluating example was given. The results show that those maintenance standards have strong objectivity and usability. 6 tabs, 1 fig, 8 refs.
