The present invention relates to a method for repairing a paved road that comprises forming a repair section by removing a damaged part of a concrete pavement or an asphalt pavement, and repairing by shooting in the repair section rapid-set blended concrete wherein concrete having improved fluidity as a result of mixing normal concrete having compressive strength of 21-30 MPa with bubbles of 20-40% of the volume of the normal concrete is mixed with a high-early-strength mixture material; and high-performance rapid-set blended concrete wherein a high-early-strength mixture material and a high-durability mixture material are mixed together. The method can thereby facilitate early opening of the repaired section, easy construction and easy maintenance by reducing construction costs and by attaining high strength and high durability. |
