Abstract

Carbon black from pyrolysis of waste tires was used to modify and improve the fatigue properties and low temperature cracking of asphalt binder. 0%, 5%, 10%, 15% and 20% of pyrolyzed carbon black was mixed. Couple of laboratory tests, such as dynamic shear rheometer test and bending beam rheometer test, were carried out. The use of pyrolyzed carbon black decreased the fatigue at room temperature and improved the resistance of low temperature cracking up to $-12^{\circ}C$, but, was off the criteria at $-18^{\circ}C$.

본 아스팔트 바인더의 피로균열 및 저온균열 특성을 개선하기 위하여 페타이어 열분해 공법의 부산물인 카본블랙을 이용하였다. 원아스팔트에 열분해 카본블랙 0%, 5%, 10%, 15% 및 20%를 혼합하였고, 동적전단유동기시험 및 처짐보유동기시험을 시행하였다. 열분해 카본블랙을 혼합한 아스팔트 바인더의 피로균열이 감소하는 경향을 나타내었고, 저온에서의 균열은 -12도까지는 개선되었으나, -18도에선 기준을 초과하는 것으로 나타났다.
