The invention, syotting the volume by 20 to 40% of the bubbles and in hard mixed concrete by joganghyeong formed by mixing a blend material, usually of concrete compressive strength of 21 ~ 30MPa by construction the lower layer portion of the concrete pavement cutting surface, and the bubbles on the upper surface thereof, is mixed into the usual securing excellence of construction and to syotting a high performance in hard-mixed concrete is formed by incorporating a joganghyeong mixed material and the durability mixing materials in the concrete by the construction of the upper part of the concrete cutting face, it enables the early opening of the compensation section also, as well as construction cost and former strength and durability by using high-performance and secure in hard-mixed concrete to facilitate the maintenance of concrete pavement repair method relates to the cross-section.
