摘    要:通过分析现行公路沥青路面养护技术规范,提出适用于旧沥青路面养护与罩面需求的沥青路面使用性能评价方法。考虑到沥青路面使用性能评价过程中的不确定性和复杂性因素,基于信息熵和多目标空间理论,建立沥青路面使用性能评价的模糊熵权多目标评价方法。其中,权重综合了专家赋权和熵值法,以同时反映评价分级的主观性和实测数据的客观性。研究结果表明:该公路沥青路面使用性能属于“次”级,与实际情况相符,表明评价方法可行。

Abstract: The needs of maintenance and overlay for asphalt concrete pavement were considered. The current Chinese technical specifications for maintenance of highway asphalt pavement were analyzed, and new evaluation method was put forward. In view of uncertainty and complexity in the process of performance evaluation, based on the entropy and the multi-objective space theory, the evaluation system was established in performance evaluation, and the fuzzy in classification of every index was considered. The weight of each index was determined by subjectivity weight method and entropy method to consider data objectivity and classification subjectivity. The result shows that the highway is of poor grade, which is matched with the fact, and indicates that the evaluation method is feasible.
