The vertical vibration compaction method (VVCM), heavy and static pressure were used to form phyllite specimens with different degrees of weathering. influence cement content, compactness, on the mechanical properties was studied. evaluated in terms unconfined compressive strength ( R c ) modulus resilience E ). Further, test roads paved along an expressway China demonstrate feasibility highly weathered improvement technology. Results show that unweathered can be as subgrade filler. In spite increasing a higher degree weathering cannot meet requirements for With improved increases linearly. increase by at least 15% 17%, respectively, every 1% content 10% 6%, compactness. phyllite, greater its properties.
