Abstract:Non-standard Proctor compaction as a soil remolding technique was compared with hand-rolling method. Non-standard Proctor compaction modified soil physical states in a large, stable and controlled manner, allowing the investigation of the co-relationship among soil density, water content, compacting work and specific soil fragmentation energy possible. It was found that density alone did not reflect cohesive soil compaction precisely; in contrary the specific fragmentation energy was more sensitive to inter-aggregate cohesion force. Therefore there is a need to refine the habit of using soil density or relative compaction as a proxy for modeling the specific traction in soil tillage research. The combined procedure of non-standard Proctor compaction and fragmentation test provided an increased exponential trend of specific fragmentation energy with respect to soil water content, while the fractal dimension of soil fragments decreased.
