Light-Weight Deflectometer
The Dynamic Plate Load Test
The dynamic plate load test is used in earthworks, civil engineering, road construction
and rail track construction. It is used to determine the load-bearing capacity and to
assess the compaction of soils, loose base courses and soil improvement in
accordance with TP BF – StB Part B 8.3.
The test method is suitable for course-grained and mixed-grained soils up to a
maximum grain size of 63 mm. The test result is displayed in MN/m². The measuring
range of the light drop weight tester lies between 15 and 70 MN/m². With the 1.5x
impact load achieved with the 15 kg loading device, the measuring range is extended
to 70 – 105 MN/m². This is required for heavy base courses in road beds and for
ballast. The measurement procedure depicted below shows the simple and quick
performance of the measurement that can be immediately printed out on site with the
integrated mini printer and stored on the chip card for later printouts at the PC.
The measurement can be evaluated on site and at the PC. On completion of every
measurement, the result can be read off from the large backlit display together with all
the measurement curves and is automatically saved in the internal memory or on an
SD card. Settling, mean values, the s/v ratio, the dynamic deformation modulus Evd,
GPS positions and the text input for the test location are also shown on the printout on
site. Up to 10,000 measurements can be transferred to the software on the PC using
the SD card. Here the test logs are displayed individually together with all the
information and measurement results, a summary of the log and the evaluation in a
statistical representation. An interface to Google Maps allows visual representation of
the respective measurement point on the map. The coordinates can also be converted
into a UTM format. Documentation is therefore very simple and traceable.
