- Description
Portable falling weight deflectometer measuring the dynamic deformation modulus of subgrade, sub-base and base layers without a reaction load. Used in highway and airfield construction for compaction control.
Specification
A guided drop weight loads a 300 mm plate through a buffer, and a velocity sensor records settlement for modulus calculation. Results are available in minutes and need no reaction load. It suits site control of earthwork and granular layers.
