In this thesis, it was considered that in durability characteristics of concrete pavements evaluation of strength characteristics as well as abrasion resistance is important as the domestic concrete pavements couldn't fulfill the public needs and cases of damage are increasing. In order to solve such problems, it is intended to compare the abrasion resistance in accordance with the mixing rate of admixtures (silica fume and polymer powder) which are incorporated in the upper layer of two-lift concrete pavement and find the optimum mixing rate for abrasion resistance by focusing on the high performance of concrete pavements through two-lift concrete pavements which use cellular sprayed concrete construction method. Both test results, which were performed based on ASTM C 779 B (dressing wheel abrasion test method) and ASTM C 944 (rotary cutter method) standards in accordance with silica fume and polymer powder mixing rate that was incorporated in the upper layer of two-lift concrete pavement, proofed that the abrasion resistance increased as the mixing rate of silica fume and polymer powder increased. However, it was also confirmed that if the mixing rate of admixtures is excessively increased it will not have an effect and it will rather decrease the abrasion resistance.

본 연구에서는 콘크리트 포장의 균열, 스폴링 등의 파손문제를 해결하기 위해 국내 시공사례가 없는 이층 포설 공법의 도입 및 기술 경제적 타당성을 검토하고자 하였다. 본 포장공법중 하나인 강섬유 보강 콘크리트(SFRC, Steel Fiber Reinforced Concrete)의 포장 배합 적용성이 검토되었다. 강섬유 함량과 포장 높이가 산정되었으며, 강섬유 보강 콘크리트의 물성 평가를 위해 압축강도, 휨강도, 휨인성 지수, 인장강도, 피로강도를 측정하였다. 슬럼프와 공기량은 대부분이 시방 기준을 만족하였으며, 28일 강도도 교통개방을 할 수준 정도로 발현되었다. 휨강도 실험 결과, 강섬유 보강 콘크리트가 무보강 콘크리트에 비해 휨인성은 증가하였지만 휨강도는 증가하지 않았다. 에너지 흡수능력, 피로 저항성 및 동결 융해저항성은 강섬유 보강 콘크리트가 무보강 콘크리트에 비해 향상되었다. 향후, 시험시공을 통해 강섬유 보강 콘크리트의 현장 적용성 및 공용성을 평가할 것이다.
