초록

안정처리된 도로 지반재료는 현장에서 환경적인 요인으로 인하여 내구성능은 여전히 구조적인 성능과 더불어 평가가 요구되고 있다. 이에 본 논문에서는 국내에서 대표적으로 활용하고 있는 기층과 노상재료를 활용하여 다양한 안정제 종류와 함유량을 달리하여 공시체를 제작하였고 동결-융해 및 습윤-건조하여 여러 조건의 반복재하 회복탄성계수시험을 실시하여 내구성능 및 특성을 파악하였다. 또한 결과에 기초하여 안정처리된 지반재료에 대한 회복탄성계수 예측모델을 살펴보고 모델계수의 범위를 평가후 문헌의 자료와 비교하였다.

A need still exists to evaluate the durability performance of cemented gedmaterials in road constructions using various cementing binders due to seasonal changes in fields as well as structural performance. In this paper, durability characteristics of stabilized granular base and subgrade materials, which is widely used in korea, was assessed using a laboratory repeated load resilient-deformation test under various freezing-thawing and wet-drying cyclic conditions. In addition, various resilient modulus models were adopted based on the test results. As a result, the estimated model coefficients agree well with the values from the literatures.
