A system for supporting maintenance of a road on which a construction vehicle travels. The system can efficiently maintain the road to effectively prevent dropping of an object carried by the vehicle and prevent deterioration in the vehicle and the tires. A construction vehicle (11) is provided with a travel position sensor (1), an acceleration sensor (2), a memory (3) for storing data continuously obtained from the sensors while the vehicle travels, a control section (5) for reading the data from the memory (3), schematizing a road, and specifying a maintenance-requiring road portion of the schematized road, and a display section (6) for displaying the schematized road and the maintenance-requiring road portion extracted from the schematized road. The control section (5) is adapted so that it specifies, as the maintenance-requiring road portion, a portion of the road, where the portion is a portion corresponding to acceleration data outside a predetermined specific acceleration condition range.
