Light Weight Deflectometer Hire

Using the 10kg falling weight the zfg 3000 light weight deflectometer lwd measures in the range of 15 70 mn m.

Light weight deflectometer hire.

The lightweight deflectometer lwd is used to test pavement system soils and prepared earth for stiffness. Light weight deflectometer s lwd s are a light weight portable tool used to determine the stiffness of unbound materials subgrade subsoils and base layers granular layers backfilling materials or partially bound material e g. The light weight deflectometer zfg 3 0 is a further development of our proven zfg 02. Olson instruments lightweight deflectometer will allow for the measurement of in situ soil modulus confirming compaction.

Light weight deflectometer for dynamic plate load test using cable or bluetooth technology. Printer pc software the dynamic plate load test performed with the lightweight deflectometer is used to determine the soil bearing capacity and compaction quality of soils and non cohesive subbases as well as for soil improvement applications. Using the 15kg falling weight 1 5 times the impact load the measuring range extends from 70 105 mn m. One single person needs only two minutes to perform the test no load vehicle as counterweight is needed.

The lwd can be used to test thin asphaltic pavements recycled materials bound with foamed bitumen and directly test the unbound subbase and subgrade. Terratest germany is offering both. Lwds provide a rapid determination of elastic modulus which is an essential factor in mechanistic design and can be used as an accurate assessment of compaction. Test the compaction quickly precisely and cost efficiently on site.

Without compact design in a measuring case this pocket sized tester can operate just as well as its big brothers. The zfg 3000 light weight deflectometer lwd with gps is used for compaction control on sub grades by measuring the modulus directly in the field accordin. Stabilised during construction or pavement rehabilitation. Lightweight deflectometer used to determine the bearing capacity and compaction quality of soils and non cohesive subbases.

Using terratest lwd is the easy and fast way to check quality of soil compaction in construction sites. It is even more convenient lighter and simpler to use than its predecessor. The measuring procedure starts with three pre loading drops for good contact with the ground. The light weight deflectometer uses a load cell and geophones with the same accuracy as the falling weight deflectometer.
