초록

골재는 주택 및 도로·항만 등과 같은 SOC건설에 사용되는 주요한 천연자원이며 국가건설의 기본이 되는 기초자재이다. 골재가 공사원가에서 차지하는 비중은 약 4%에 불과하나, 골재는 건설공사 용적의 약 80%를 점유함으로서 건설공사의 양과 질을 좌우하는 필수요소이다. 하천, 수중, 하상, 바다, 육상 골재는 생산시 환경 문제와 제한된 부존량으로 인해 골재수급에 어려움이 발생할 경우 골재의 생산량을 급격하게 증가시키기 어려운 반면에 산림골재는 증산이 비교적 용이하다. 산림골재는 부존량이 풍부해 향후 다른 골재 감축시 대체 골재자원으로 유망하게 평가받고 있으며, 잘 짜여진 계획과 정책에 따라 골재수요에 유연하게 대응할 수 있는 효과적인 골재재원이다. 본 연구에서는 산림골재 개발에 큰 영향을 미치는 운반거리를 중심으로, 운반거리가 긴 경우와 짧은 경우에 대해서 산림골재 활성화 방안과 더불어 현재 산림골재 개발의 난제에 대한 대책을 제시하였다.

Aggregate is a major natural resource used in SOC construction, such as housing, roads, ports, etc., and is a fundamental material for national construction. Although aggregates account for only about 4% of the construction cost, aggregates occupy about 80% of the construction volume and are essential factors that determine the quantity and quality of buildings. For river, underwater, riverbed, sea, and land aggregates, it is difficult to rapidly increase the production of aggregates when there is difficulty in supply and demand due to environmental problems and limited resources during production, whereas forest aggregates are relatively easy to increase production. Forest aggregates are considered promising as alternative aggregate resources in the future when reducing other aggregates due to their abundance of natural resources, and are an effective aggregate source that can flexibly respond to aggregate demand in accordance with well-organized plans and policies. This study proposed the plan for activating the development of forest aggregates in the case of long and short transport distances, which is a factor that has a great influence on the development, and measures for the current difficulties in forest aggregate development
