The Jiuzhaigou M_S7.0 earthquake has caused massive damage of Provincial Road S301 and County Road Z120 in the hardest hit areas, which brought great difficulties for emergency rescue and post-earthquake reconstruction. With the high resolution UAV and satellite images, it is possible to evaluate road damage. First, the types of road damage are classified, and the extents are rated. According to the characteristics of road damage in images of different resolution, the interpreting signs for different damage extents and types are established. In the assessment, there are 110 obvious spots of damage in the study area, of which 68 are partially damaged, and 42 are completely destroyed. The whole road is badly damaged. The method of road damage assessment by high resolution remote sensing images can provide important information for the rapid dredging of "life line" after earthquake.
