Plate Load Test &
Equivalent CBR Testing
What is a Plate Loading or Equivalent CBR Testing?
An in-situ method of testing to determine the grounds bearing capacity.
Why conduct Plate Loading or Equivalent CBR Testing?
Testing is conducted to determine how the ground will act under pressure when loaded, for example:
-
Lifting Operations (Cranes, HIABs)
-
Piling Mat/Platform Construction
-
Carriageway/ Foundation Design
-
Use of Larger Site Accommodation
-
Use of Concrete Pumps
When and Where are the Plate Loading or Equivalent CBR Testing tests conducted?
Depending on the use case, tests can be conducted:
-
Prior to design and used to inform design
-
Prior to the use of certain plant/equipment
-
To provide an assurance check of the installed design
Tests are conducted at the location of the loading requirement.
How are the Plate Loading or Equivalent CBR Testing tests conducted?
All our Plate Load Testing is carried out in accordance with BS1377:1990 Part 9. A brief overview of the test is as per the below:
-
Setup Loading Plate and associated equipment under sufficient kentledge (minimum 8 tonnes depending on requirement)
-
Apply load to plate in 5 increments, deflection readings taken every minute until detectable movement has stopped
-
Continue testing until required loading has been met.
-
Calculation of Load-Settlement Curve, Modulus of Subgrade Reaction (K) and an Equivalent CBR value.
