| Zusammenfassung: | A method for repairing a paved road 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. |
