| Rock produced in situ has been used as the road construction materials in consideration of economies. However, because sedimentary rock is rapidly weathered, it is hard to decide appropriateness of quality specifications. This study aims at evaluation of usability for sub-base of muddy stone produced in situ. Test results show that the abrasion ratio is fitted for specifications, but weight loss in 37.5$sim$16mm after Los Angeles abrasion test shows 47% in muddy stone in comparison with 20$sim$30% in gneiss and sandstone. The soundness of aggregate shows higher value in muddy stone than in gneiss and sandstone. The weight loss from accelerated weathering test due to freezing and drying show 58% in muddy stone in comparison with 308$sim$21% gneiss and sandstone. |
