The light weight deflectometer lwd is a light weight portable tool used for measuring the bearing capacity deflection of subgrade subsoils and unbound base layers granular layers and backfilling materials.
Light weight deflectometer test procedure.
The measuring procedure starts with three pre loading drops for good contact with the ground.
Using the 15kg falling weight 1 5 times the impact load the measuring range extends from 70 105 mn m.
Using terratest lwd is the easy and fast way to check quality of soil compaction in construction sites.
Lwd measurement is quicker than the isotope measuring method and requires no reference measurements.
No extra electronic device is needed all test data will be stored immediately on your own smartphone or tablet.
Light weight deflectometer for dynamic plate load test using cable or bluetooth technology.
A light weight deflectometer lwd is a portable falling weight deflectometer used primarily to test insitu base and subgrade moduli during construction.
Light weight deflectometer lightweight deflectometer buy for best price.
Using the 10kg falling weight the zfg 3000 light weight deflectometer lwd measures in the range of 15 70 mn m.
The zone of influence for the test typically extends to between 1 and 1 5 times the plate diameter.
The app is available for ios and android.
