Semi-Circular Bend (SCB) Test Fixture

Model: MS-45
$680.0000
Price: $680.00

Used in Marshall Stability Load Frames, this fixture determines low-temperature fracture energy and toughness of asphalt mixtures with a maximum aggregate size of 19mm. Semicircular asphalt specimens are easily cut from Superpave™ Gyratory compacted cylinders or field cores with a diameter of 150 mm.

The MS-45 Semi-Circular Bend (SCB) Test Fixture consists of a 0.5in (12.7mm) thick steel base plate, two L-shaped roller support steel blocks, two steel rollers, and a U-shaped frame. The test fixture is mounted for loading in a Marshall Load Frame such as the MS-86 or MS-398.

A specimen is positioned with the flat side on two rollers and a load applied along the vertical diameter of the specimen. Load and displacement are measured to calculate test results. Initial roller position is maintained by soft springs and backstops, which establish the test span dimension.

  • Determines low temperature fracture energy and toughness of asphalt mixtures with a maximum aggregate size of 19mm
