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.
