Most frequently, vibratory rollers are used for compaction tasks during earth works and road construction. An increase in the roller performance can be achieved by automatically adapting the machines parameters which determine the compaction result and by automatically controlling the state of compaction continuously. The actual problem is, that because of the extensive variety in properties of the materials to be compacted and the conditions in jobsite, it is very difficult to state the criteria for the feedback control of the roller parameters. By means of modeling and simulating, the vibration behavior and compaction effect as well as the interdependence between the state of roller-operation and the state of soil-compaction is investigated. The goal is to acquire knowledge about the interactions between vibratory rollers and soil during compaction in order to improve roller construction and automatic compaction measuring systems.
