Light Weight Deflectometer HMP LFG - The easy way of compaction control
The test method
The dynamic plate load test by means of the Light Weight Deflectometer enables an uncomplicated bearing capacity test and compaction control of soils, non-cohesive subbases and soil improvements – within only 2 minutes – just place the device, measure and evaluate immediately!
Inbuilt soil layers can be tested very quickly and without load abutment, facilitating quick assessments of test lots even under limited space conditions. The test method is suited for coarse-grain and mixed grain soils having a maximum grain size of 63mm and can be used to determine the dynamic modulus of deformation of soil in the range of Evd = 15...70 MN/m².
The dynamic plate load test is described in the Engineering Code for Soil and Rock in Road Construction TP BF-StB part B 8.3 issue 2012. Detailed correlations to other test methods exist.
Areas of application
- Road- and railway construction, earthworks
- Quality assurance in canal construction
- Compaction control in pipe trenches
- Testing of pavement beddings
- Testing of foundation backfill
- Quality inspection in boreholes
- Testing of modulus of deformation within the framework of soil examination
By means of the Light Weight Deflectometer HMP LFG you are able to purposefully manage and control your compaction works and to improve the quality of your construction. This gives you confidence, saves time and money!
Self-monitoring saves costs!
The Light Weight Deflectometer HMP LFG is especially suitable for in-house self-monitoring, due to the easy handling and the immediately available measurement results. This facilitates quick decisions to continue construction work at the site. Minimize your costs by avoiding unnecessary compaction works but also optimize the quality of your construction project.
Convince your customer by proofing the quality assurance of your construction site. Prevent f. e. expensive recourse claims because of subsidence damages. Document your measured data directly at the site via printout by means of the thermal printer or as protocol printout after transferring and reliable archiving the measurement series onto your PC.
