SELF-HEALING ASPHALT COMPOSITION AND METHOD FOR ACCELERATION OF CRACKS SELF-HEALING OF ASPHALT CONCRETE STRUCTURE USING THE SAME

PARK DAE WOOK

Abstract

The present invention relates to a self-healing asphalt concrete composition containing steel fiber, asphalt, and aggregates containing steel slag. The present invention further relates to a method for facilitating self-healing of cracks on asphalt concrete structure produced by using the composition. By increasing resistance to fatigue cracks on the asphalt concrete structure using the same, it is possible to prevent turtle back cracks and potholes. In addition, by the method for facilitating self-healing of cracks on the asphalt concrete structure, reduction in maintenance costs is possible while increasing lifespan of road, since the self-healing asphalt concrete composition can be strongly regenerated after cracks are formed on asphalt.

본 발명은 스틸 슬래그를 포함하는 골재, 아스팔트, 및 스틸 파이버를 포함하는 자가치유형 아스팔트 콘크리트 조성물 및 상기 조성물을 이용하여 제조된 아스팔트 콘크리트 구조물의 균열 자가치유 촉진 방법에 관한 것으로 이를 이용한 아스팔트 콘크리트 구조물의 피로균열 저항성을 향상시켜 거북등균열, 포트홀 등을 예방할 수 있고, 상기 아스팔트 콘크리트 구조물의 균열 자가치유 촉진 방법을 제공하여 아스팔트 균열이 발생한 후에도 견고하게 재생이 가능하여 도로의 수명을 향상시키고, 유지관리비용을 감소시킬 수 있다.
