A plate bearing test is an in-situ load-bearing test carried out on various material types/conditions such as soil, hydraulically bound and unbound materials, existing surfaces, working platforms, crane outrigger pads, piling mats and trial pits. Plate-bearing tests are used for various purposes, such as determining the ground's ultimate bearing capacity and settlement.
TerraTek is UKAS accredited to carry out this testing BS 1377 Part 9: 1990 standard. We are also UKAS accredited to determine equivalent CBR values from plate load testing, commonly used to assess the strength of sub-grade material in road/pavement design - advantageous when testing materials which contain particle sizes above 20mm, and direct CBR tests may not be suitable.
Additionally, we can perform plate bearing testing to calculate strain modulus and modulus ratio (Ev), which is typically tested in accordance with DIN 18134 standard and commonly used in projects such as wind farm construction.
This measurement is divided by the pressure needed to achieve an equal penetration on a standard and high quality crushed rock material. The harder the surface, the higher the CBR value.
Terra Tek carries out plate load testing nationwide as part of our comprehensive in-situ test offering.
