Saferoad MEGARAIL - Soil test criteria; Recording Foundation Test Results

23 Revision 33 October 2022
7.2 Soil test criteria
Sigma 100 driven post, driven foundation and concrete foundation
A bending moment of 6.5 kNm (6500Nm) must be achieved before the posts
deflection exceeds 100mm.
C 125 driven post, driven foundation and concrete foundation
A bending moment of 8.5 kNm (8500Nm) must be achieved before the posts
deflection exceeds 150mm.
C100 with or without stiffener driven post, driven foundation and
concrete foundation
A bending moment of 8.5 kNm (8500Nm) must be achieved before the posts
deflection exceeds 150mm.
Mega Flex Transition Post Z section driven and foundation
A bending moment of 9kNm (9000Nm) must be achieved before the post
deflection exceeds 150mm.
The deflection should be measured at 610mm. See loading chart page 26.
Mega Guard Post H section foundation only, no driven post available.
A bending moment of 9kNm (9000Nm) must be achieved before the post
deflection exceeds 100mm.
The deflection should be measured at 610mm. See loading chart page 26.
7.3 Recording Foundation Test Results
Foundation test results should be recorded on a test result form an example
of this is shown on the next page.
Notes should be made on the form of the testing kit that was used for the
test and the identification number of the calibration certificates
