Title: 다짐온도에 따른 변형강도 변화를 통한 아스팔트 콘크리트의 철도노반 적용성 평가
Abstract: Since asphalt concrete is widely used for railroad base in advanced countries due to many advantages, the preliminary research for its applicability is necessary in Korea. Asphalt concrete is prone to deform (rut) in hot environment, and therefore, the rut resistance of asphalt concrete for railroad is also need to be evaluate. The rut resistance of hot-mix asphalt (HMA) concrete and warm-mix asphalt (WMA) concrete was evaluated to determine optimum compaction temperature (OCT) using deformation strength (SD). The results showed that OCT values of normal asphalt HMA and WMA were 135℃ and 105℃ , respectively, and those of polymer-modified HMA and WMA were 155℃ and 125℃, respectively.
