초록

본 연구는 자동차 파쇄 잔재물의 활용성을 알아보고자 폐차과정에서 발생되는 폐나일론 섬유를 아스팔트 콘크리트에 첨가하여 일반 아스팔트 콘크리트와의 피로수명 비교, 경제성 분석을 실시하였다. 4점 휨 피로 시험을 수행한 결과 일반 아스팔트 대비 피로수명이 10% 향상되었으며, 이를 통해 경제성 분석을 실시하여 35년간 약 5.4억 원의 유지보수비용에 대한 비용 절감을 가져 오는 것으로 확인 되었다. 폐나일론 섬유 보강 아스팔트는 비용절감 효과와 더불어 폐자재의 환경처리비용 이점과 활용성 측면에서의 친환경적 공법으로 생애주기비용분석에서보다 더 큰 경제적, 사회적 효과가 발생 할 것으로 판단된다.

In this study, discharged nylon fibers were added to asphalt concretes to be compared with fatigue life and analyzed in economic point of view. A four point bending fatigue test was conducted, and as a result, nylon fiber reinforced asphalt concretes that showed a 10percent increase in fatigue life compared to ordinary asphalt concrete. The economic analysis confirmed that the maintenance cost was decreased by 540 million won throughout the analyzing period. It is thought discharged nylon fiber reinforced asphalt will cause more economic and social effects than was shown by life cycle cost analysis.
