摘　　要：公路路面质量的好坏对行车安全性、舒适性、经济性有重要的影响,因此路面状况的监测对于公路交通的健康发展具有重要意义。遥感技术作为一种新兴的数据采集手段,具有图像覆盖范围大、时效性强、信息客观现实、可重复使用、便于计算机分析等优势,为解决大范围的路面监测问题提供了强有力的支持。本文综述了现有基于遥感技术的道路路面状况监测方法,对其中存在的问题进行了分析和探讨。遥感技术在路面状况监测中具有广泛的应用前景,部分技术已经成熟并在公路养护作业中广泛使用,例如路面监测管理系统、探地雷达等;但是仍有部分技术还存在着鲁棒性差、精度较低等问题,还需要进一步的研究探索,如路面光谱分析、基于机载和星载的路面状况遥感监测应用的适用性等。本文最后给出了一种基于多端元混合像元分解模型的沥青路面老化状况监测与评估方法的研究实例。实验结果证明该方法可有效区分沥青公路路面混合像元中不同老化状况的沥青路面,为大范围路面老化状况监测提供了一种技术途径。Roads are greatly essential in a transportation system. The quality of road pavements has a crucial impact on the driving safety, comfort, and the cost of the roads. Therefore, timely monitoring the pavement conditions to guarantee the secure operation of the traffic sys-tem is significant. Currently, time-consuming field investigations and manual measurements are the conventional and main methods to de- tect and evaluate the pavement conditions. However, many of these methods are destructive to the road surface. Many forms of remote sens- ing data without destructive effect on pavement were introduced with the support of computer technology and remote sensing to detect pave- ment conditions, such as digital images, LiDAR, and Radar. This paper reviewed the current research status and problems in pavement con- dition detection based on remote sensing technologies. Remote sensing, as a non-intrusive method, has the advantages of wide spatial coverage and objective and repeatable data with high temporal resolution that can be analyzed by computer conveniently. Generally, the methods can be divided into four types, namely, the multi-/hyper-rernote sensing, the thermal remote sensing, the microwave remote sensing, and three dimensional reconstructionbased on the categories of the sensors used in pavement monitoring. The multi-/hyper- remote sensing primarily utilizes the reflective spectral informa- tion of the pavement, which contains three specific methods, namely, image processing method, the method based on the variation of pave- ment brightness, and spectral modeling. The thermal remote sensing is based on the radiation characteristics of pavement, which contains two methods based on the variation of pavement temperature and emissivity information. A microwave device called Ground Penetrating Radar （GPR） has been widely used to detect the pavement defects by road departments. The three dimensional information of the road sur- face can be acquired using photogrammetry and LiDAR systems to measure the elevati
