BOMAG Terrameter (BTM)
|The Terrameter compaction measuring system is a popular tool for economical compaction and continuous assessment of compaction during and after the compaction process. It is used for continuous dynamic compaction control (CCC).
The Terrameter continuously determines the dynamic soil stiffness and shows the driver the EVIB-values [MN/m²] on the display. A printer for track-by-track documentation of the EVIB-values is optionally available. The EVIB-value is directly associated with the deformation modulus EV2 resulting from the static plate load test. With the Terrameter qualitative and quantitative assessment of compaction and load bearing capacity of soils in earthwork and road construction is possible. The BTM supports roller drivers, site managers and technicians in the laboratory. It indicates when no further compaction is possible and locates and documents soft spots and non-uniform areas. The Terrameter saves unnecessary passes, time and fuel and ensures better and more uniform compaction quality.
All BOMAG single drum rollers can be equipped with BTM which, however, is standard on single drum rollers with VARIOCONTROL.
The Terrameter consists of two acceleration transducers, the path meter, the electronics unit, the control and display unit and a printer (optional).
