摘要
针对路面结构性能与表面性能衰变之间关系的研究,多为关注2种性能评价指标均值间的关系,少有考虑指标变异系数间的关联性。文中以某高速公路为依托,基于4个路段的路面性能检测数据,对表面性能与结构性能进行单独分析。并对两性能评价指标间的均值和变异系数进行对比分析,结果表明,2个指标均值间的相关性不明显,但指标变异系数间相关性强。若基于评价指标均值,则可能忽略局部异常路段,故应对路面性能评价指标的变异性予以更多重视。
There are only a few studies on the relationship between pavement structure performance and surface performance deterioration,and more attention is paid to the relationship between the average values of the two performance evaluation indicators,and less consideration is given to the correlation between the variation coefficient of the indexes.Taking an expressway in Ningbo as the support engineering,the surface performance and structural performance of four pavement sectionsare analyzed separately based on the pavement performance test data of four sections.The mean value and variability of the evaluation index of surface performance and structural performance are comparatively analyzed.The results show that the correlation between the mean value of the two indexes is not evident,but the variability of the index is correlated.If it is based on the average value of the evaluation index,some local abnormal sections may be ignored.Therefore,more attention should be paid to the variability of pavement evaluation index.
