Light Weight Deflectometer ZFG 3.1 is used to determine the dynamic defor- mation modulus Evd in MPa [MN/m²] by means of the dynamic plate load test.
Test results provide conclusions on the bearing capacity and compaction qua- lity of soils. The main field of application for LWDs is earthworks in transport infrastruc- ture construction. Further applications are soil investigation and landscaping.
