Terratest germany is offering both.
Light weight deflectometer hire.
The lightweight deflectometer lwd is used to test pavement system soils and prepared earth for stiffness.
It is even more convenient lighter and simpler to use than its predecessor.
Olson instruments lightweight deflectometer will allow for the measurement of in situ soil modulus confirming compaction.
Lightweight deflectometers lwds are increasingly being used to determine overall compaction quality of all types of earthworks through their use as a qc qa field test.
The lwd can be used to test thin asphaltic pavements recycled materials bound with foamed bitumen and directly test the unbound subbase and subgrade.
The light weight deflectometer uses a load cell and geophones with the same accuracy as the falling weight deflectometer.
The measuring procedure starts with three pre loading drops for good contact with the ground.
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.
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.
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.
Without compact design in a measuring case this pocket sized tester can operate just as well as its big brothers.
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.
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.
Compaction tests in just 2 minutes.
Test the compaction quickly precisely and cost efficiently on site.
Light weight deflectometer for dynamic plate load test using cable or bluetooth technology.
Using terratest lwd is the easy and fast way to check quality of soil compaction in construction sites.
The light weight deflectometer terratest 5000 blu.
Stabilised during construction or pavement rehabilitation.
