PURPOSE: An asphalt road repairing method by on-site heating is provided to integrally perform on-site heating, supplementing, and compacting, and to prevent the occurrence of defects by completely integrating new and existing asphalt mixtures without generating a joint. CONSTITUTION: An asphalt road repairing method by on-site heating comprises the following steps of: cleaning an area for repairing and removing stagnated water and foreign substances; marking "L" shapes on areas in which the upper corner of an infrared heating unit is planned to be settled; moving asphalt repairing road equipment to a proper spot, and subsequently igniting and preheating the infrared heating unit; locating the infrared heating unit to "L" shape marked areas for repairing by operating an infrared heating unit operating device; heating the areas for repairing for 4-9 minutes depending on the depth, season, and frame by the infrared heating unit; perpendicularly erecting the infrared heating unit by operating the infrared heating unit operating device, and obtaining a working space by forwardly moving a vehicle; making an existing asphalt mixture on the heated spot from the boundary to the center through a rake and a shovel, and finely smashing into particles; removing a part of the existing asphalt mixture to the outside when necessary; discharging a new asphalt mixture from a new asphalt mixture storing unit into a transporting unit; pouring the new asphalt mixture into the area for repairing; making the new asphalt mixture on the entire area for repairing by a rake; and rolling the area from the boundary to the center, cleaning, and finishing the area.
