Roads，as typical man-made objects，have attracted considerable attention in the field of remote sensing. Previous research has predominantly focused on geometrical feature extraction，with relatively insufficient attention paid to road attribute information such as material, classification, and surrounding features. However，road attribute information is crucial for road management，urban planning，and more. Considering the inherent engineering and geographical relationships among these road attributes，this study adopts a multi-task learning approach. We propose a method for extracting road attributes from visible remote sensing images based on multi-task learning，utilizing a residual network integrated with a channel attention module as the backbone. This is further enhanced with a foreground auxiliary module and a feature pyramid module to augment the focus on road targets and the capability for multi-scale processing. Ultimately，the study achieves the classification of road material，classification，and surrounding feature types (background) in visible remote sensing images. and proved the overall accuracy of the network，demonstrating that convolutional networks can effectively extract features and learn engineering and geographical relationships. In the application to the periphery of a nuclear power plants，this method addressed the complex environment and strategic importance of nuclear facilities，validating its effectiveness in practical scenarios，which is of significant importance for ensuring the safe operation of nuclear power plants and the rational planning of surrounding areas.
