Static plate load test HMP

The Static Plate Load Test applies in earthworks and foundation engineering as well as road construction in order to determine load settlement lines and by this to evaluate the deformability and the load capacity of the soil.

For test evaluation, the settlements of each loading stage and the corresponding average normal stress under the load plate are shown in a diagram as load settlement curves.

The modulus of deformation Ev is determined from the load settlement line of the first load (Ev1) and the second load (Ev2). Through the first loading a certain remaining deformation always obtains and therefore the proportion of the accordingly higher Ev2 value to the Ev1 value provides an indication to the attained compaction.

By means of the Static Plate Load Tester HMP PDGpro immediately after test procedure the deformability and the load capacity of the soil as well as the quality of the construction work can be assessed and documented on the construction site.

To carry out the test a counterweight of at least 5 t is required. Set up and test procedure can be done by one person. The handling of the measuring instrument is comfortable and very user-friendly. Faulty measurements are almost impossible when handled properly.

The pure test procedure according to DIN 18134 with 15 loading stages takes about 30 minutes and allows immediate conclusions on the load capacity and deformability of soils down to the depth of twice of the load plate diameter. By specifying the GPS coordinates, the measuring point is recorded.

For subsequent post-processing and protocol creation on the PC, the measured values can be exported via USB stick or cable.
