摘要:
针对大范围公路路面健康状况快速监测与评估需求,基于地面光谱测量获取的路面光谱数据,对不同老化程度的沥青路面光谱特征进行了分析,通过求导和包络面去除等方法得出老化沥青路面和新沥青路面在400~680 nm、860~970 nm两个波段范围内存在显著光谱特征差异。然后基于这些特征波段构建了沥青路面老化乘积指数(Multiplication Aging Index,MAI)模型,并利用北京房山良乡地区的WorldView-2卫星影像来刻画沥青路面在道路使用中出现的老化状况。通过与地面实测光谱数据和路面状况描述进行对照,将实地测量得到的Munsell明度色卡值与本文提出的MAI指数进行了统计分析,结果表明:该MAI指数能较好地反映沥青路面的老化状况,可实现对研究区内14条沥青道路的老化状况进行遥感监测与评价,研究结果可为道路管理部门制定养护规划提供新的技术手段。

Abstract: To meet the demands in monitoring the health conditions of road pavements over a relatively large area,by means of derivative and continuum removal approaches this study analyzes the spectral features of asphalt road pavements aging degrees based on the field measurements of pavement spectra.Distinct spectral features of new and aged asphalt road pavements were observed in the wavelength regions of 400~680 nm and 860~970 nm.After that,a WorldView-2 image in Liangxiang area,Fangshan district,Beijing City were captured and the corresponding bands were used to create a Multiplication Aging Index (MAI) to reflect the aging conditions of asphalt road pavements.Comparison between the MAI and in-situ measurements of the spectra and aging conditions of the road pavements in the study area was performed,and statistical analysis was also conducted based on the Munsell brightness values collected in the field investigation.Through the contrast,the aging condition from MAI has good relevance to the in-situ measurements.Results indicate that the proposed MAI index can reflect the aging conditions well and is further used to monitor the pavement quality of the 14 road pavements in the study area.According to the evaluation,six roads in the study area need road maintenance.The research can offer a new technology for road management departments to make their road maintenance plans.
