Dynamic Load Plate Test quick and easy
Dynamic plate load test is a reliable test to avoid damage in earthworks, road construction and civil engineering. The audio-guided test is worldwide accepted. The determined dynamic deflection module Evd (according to the Technical Test Code for Soil and Rock Mechanics in Road Constructions – TP BF-StB Part B 8.3) is measured in Megapascall (MPa). It is being used in road and pipe construction as well as in earthworks, in order to judge the compaction quality of mounted layers, even while still in the construction phase. Thanks to the dynamic load plate test the executing company is able to assess the correct compaction of the ground layer by layer with their own staff. If the different layers are only being checked at the end of the earthworks, for example by using dynamic probing, extensive costs for dismounting, re-compacting and re-assembling the ground must be expected in case of poor compaction quality of the lower layers.
TERRATEST 7000 STREAM is especially suitable for compaction tests in areas that are difficult to access like utility trenches, shafts and backfills. Furthermore, tests can be performed throughout the compaction works, allowing for these to be conducted precisely and effectively. A further advantage is that the entire area, not just parts, of the construction field can be checked for a homogeneous compaction quality in a minimum of time. The test results can be evaluated and printed directly on site.
Thanks to the easy, intuitive operability of TERRATEST’s measuring devices even non-experts can perform the dynamic load plate test.
What is a Dynamic Load Plate Test?
The dynamic load plate test is a rapid testing method in accordance with TP BF-StB Part B 8.3 used to assess the load-bearing capacity of soils and rock in earthworks and road construction. The test can be performed by a single operator using a Light Weight Deflectometer (LWD).
During the test, a 10 kg drop weight is released from a defined height of approximately 71 cm onto a circular steel load plate with a diameter of 300 mm. The resulting soil deformation is measured by a sensor mounted at the center of the load plate. Based on this deformation, the measuring unit calculates the dynamic deformation modulus Evd in MPa, which is an indicator of soil stiffness and bearing capacity.
Advantages of the Dynamic Load Plate Test
Compared to the static plate load test, the dynamic load plate test offers several advantages:
- Easy operation: The test can be carried out reliably and reproducibly even by non-specialist personnel.
- Very short testing time: One measurement takes about 2 minutes, whereas the static plate load test requires around 30 minutes.
- Area-wide quality control: Due to the short testing time, many measurements can be performed in different layers, ensuring a high level of construction quality.
- Suitable for hard-to-access locations: Tests can easily be performed in trenches, narrow construction areas, and backfilled zones.
- No counterweight required: Unlike the static method, no roller or other counterweight is needed.
- No interruption of construction work: Compaction work can continue during measurements; operating rollers or other machinery do not affect the test results.
How is the Dynamic Load Plate Test performed?
The test is carried out using a Light Weight Deflectometer (LWD) consisting of:
- a loading device with a 10 kg drop weight and guide rod,
- a circular load plate with a diameter of 300 mm, and
- a settlement measuring system, which may be a measuring computer or a smartphone with a dedicated app.
First, three preloading drops are applied, followed by three measuring drops. The drop weight is released from the upper release mechanism and strikes an impact plate, which transfers the force impulse to a spring package consisting of 17 disc springs. The impulse is then transmitted to the load plate, which must rest fully and evenly on the surface being tested.
A sensor mounted at the center of the load plate measures the vertical deflection and transmits the data to the measuring unit. The unit then calculates the dynamic deformation modulus Evd (MPa). This value represents the stiffness of the soil and therefore provides reliable information about the degree of compaction and load-bearing capacity.
Which equipment is used to perform the Dynamic Load Plate Test?
The dynamic load plate test is a proven method for determining the load bearing capacity and compaction quality of soil in road construction, earthworks, pipeline installation, and foundation preparation. Reliable results from a dynamic load plate test ensure safe construction processes and long-term structural performance.
A Light Weight Deflectometer enables fast, precise, and on-site execution of the dynamic load plate test. The device generates a defined impact load and measures the resulting surface deflection to calculate the dynamic modulus in MPa. Within just a few minutes, engineers and contractors receive reproducible measurement results for immediate evaluation of soil compaction and load bearing capacity.
As illustrated in the adjacent exploded view, the Light Weight Deflectometer used for the dynamic load plate test consists of a hardened drop weight, a precision guide rod, a heavy-duty load plate with an integrated acceleration sensor, and a calibrated spring system that transfers the impact force in a controlled impulse duration. The robust mechanical design complies with ASTM E2835-11 and TP BF-StB Part B8.3, ensuring reliable and comparable measurement results.
All components are manufactured from high-strength structural steel to guarantee maximum durability under harsh construction site conditions. Combined with intuitive operation and digital documentation options, the Light Weight Deflectometer delivers a professional solution for accurate and repeatable dynamic load plate test measurements worldwide.
