5. Jig Setup
The SCB jig is designed to comply with the requirements of both
the I-FIT and LSU SCB standards. The difference in the jig for the
standards is the spacing between the rollers. The I-FIT (AASHTO
TP 124) test requires an 120 mm spacing while the LSU (ASTM
D8044) test requires an 127 mm spacing.
1. Remove the two screws (5/32” Allen wrench) from the
roller support, as shown in the circles in Figure 3.
2. Flip the mounting block around until it is oriented like
the appropriate method.
a. I-FIT – the mounting block is flush to the roller
support.
b. LSU – the mounting block overhangs the roller
support.
