Abstract

The new asphalt surface reinforcement method (ASRM) is one of the preventive maintenance methods in asphalt concrete pavements. The adhesion performance of new ASRM satisfied the standard of non-slip pavement and bridge waterproofing materials. As a results of durability tests (as wheel load, rolling bottle and UV resistance test), the new ASRM showed sufficient resistance to traffic and environmental loads. The waterproof and chemical resistance tests of new ASRM were conducted to evaluate whether the pavement could be protected from water and chemicals and the performances of new ASRM were satisfactory. Furthermore, the new ASRM demonstrated some rejuvenation effects due to its toughness increases in recycled asphalt concrete mixture by 5% compared to the conventional hot mix asphalt mixture using reclaimed asphalt pavement. In conclusion, the new ASRM was evaluated to protect the asphalt concrete pavement and increase the lifetime.

아스팔트 콘크리트 포장의 예방적 유지보수방법 중 하나인 표면강화공법의 실내 성능 평가를 수행하였다. 표면강화공법과 아스팔트 콘크리트 포장과의 부착력 평가 결과 미끄럼방지 포장 및 교면방수재료 기준을 상회하는 부착성능을 나타내었다. 윤하중재하실험과 박리저항성, UV저항성 실험을 통해 교통 및 환경하중에 대해 충분한 내구성을 확보할 수 있는 것을 확인하였다. 표면강화공법은 내투수성과 내화학성이 뛰어나 포장내로 수분 침투를 막고 화학물질로부터 포장을 보호할 수 있으며, 노화된 아스팔트 바인더의 재생효과가 있어 재생 아스팔트 콘크리트에 적용하였을 때 재래식 가열 아스팔트 콘크리트 혼합물에 비하여 약 5%의 터프니스를 증가시켰다. 아스팔트 표면강화공법은 아스팔트 콘크리트 포장의 내구성을 향상시킬 수 있는 특성을 갖는 것으로 나타났다.
