Characteristics and Methods Research on Heavy Compaction and Vibration Compaction of Graded Crushed Aggregate

摘要

Graded crushed aggregate mixture form internal friction resistance rely on the interlocking and friction effects between the particles ,with high shear strength and resistance to deformation, which is difficult to compacted. Through the analysis of factors affecting the compaction properties of materials,self-vibration phenomenon and resonance phenomenon, theoretical study on the effect of shear strength of the material vibration, the comparative experiments were conducted by heavy compaction instrument and vibration compaction instrument, accommodate compaction property of graded crushed aggregate, the test methods were obtained, also the test parameters were determined, and verified by experiment.
