폐콘크리트의 도로 건설재료로서 적용성 평가

Abstract

In this study, the engineering and environmental properties of the concrete waste are investigated, and the applicability as the road construction materials is evaluated. The concrete waste can be classified according to the collection method such as simple and crushed collection. The engineering and environmental properties are different in each collecting method. The concrete wastes by the simple and crushed collection are not suitable for the road material standard of sub-base layer. The concrete wastes cannot be applied to the material of sub-base layer. If the modified CBR(California Bearing Ratio) value of the crushed collection will be improved, the concrete waste by the crushed collection can be used the road material of sub-base layer. Meanwhile, the concrete wastes by the simple and crushed collection are satisfied with the road material standard of anti-frost layer. The concrete wastes can be applied to the material of anti-frost layer.
