The dynamic response of vibratory rollers during compaction is examined. A two-degree-of-freedom model has been established for analytical representation of the soil-roller interaction. The characteristic responses of the vibratory roller have been presented using the model. To check the validity of the theory, a series of full-scale field experiments was conducted. The experimental results agreed well with the theoretical predictions. The understanding of basic vibratory-roller behavior derived from this study provides a basis for understanding the fundamental principles of vibratory-roller compaction.
