초록

본 연구는 도로 노체 적용이 불가능한 원지반토와 순환자원을 활용한 지반안정재를 적용하여 도로 노체의 요구성능(양생 28일 기준 일축압축강도 : 0.44MPa)을 확보하는 최적 혼합비율을 도출하고자 하였다. 이를 위하여 3가지의 지반안정재 혼합비율(1m3당 80kg, 100kg, 120kg)에 대해 양생 3, 7, 14, 28일에 일축압축강도를 측정하였다. 양생일 및 혼합비별 일축압축강도를 측정한 결과 순환자원 활용 지반안정재의 혼합비율이 증가하면 일축압축강도 증가하는 것으로 확인되었으며, 도로 노체의 요구성능을 만족하는 1m3당 100kg 이상의 순환자원 활용 지반안정제를 혼합해야 되는 것으로 확인되었다.

This study aimed to derive the optimal mixing ratio that secures the required performance of the road body(unconfined compressive strength: 0.44 MPa based on 28 days of curing) by applying soil stabilizer utilizing recycled resources and the in-situ soil that cannot be applied to the road body. To this end, the unconfined compressive strength was measured for three mixing ratios of soil stabilizer (80 kg, 100 kg, and 120 kg per 1m3) at 3, 7, 14, and 28 days of curing. As a result of measuring the unconfined compressive strength by curing day and mixing ratio, it was confirmed that the unconfined compressive strength increased as the mixing ratio of soil stabilizer utilizing recycled resources increased. It was confirmed that more than 100 kg of soil stabilizer utilizing recycled resources per 1m3 should be mixed to satisfy the required performance of the road body.
