Plate Load Testing

The Plate Bearing Test (or Plate Loading Test) is an insitu load bearing test of soil used to determine the ultimate bearing capacity of the ground and the likely settlement under a given load.

While site investigations for most projects consider ground conditions at depth, the strength and variability of the near surface ground is critical for the design and operation of working platforms. The Plate Bearing Test is typically used in the design of temporary working structures such as working platforms for piling rigs or pads for crane outriggers. Approximate equivalent KPA and CBR values can be derived from the Modulus of sub grade reaction by use of mathematical relationship.

The Plate Bearing Test is carried out in accordance with DIN18134-2012. It consists of loading a steel plate of known diameter and recording the settlements corresponding to each load increment.

Pearce Geotech’s latest technology AX01 Plat Load Testing units provide safe, accurate, on site results in under 30 minutes. We have also achieved NATA accreditation for this test method.
