Listing ID #3326422

The Roller Compactor is considered to be the method of laboratory specimen compaction that results
in slabs of asphaltic paving materials with properties that most closely simulate those of materials in the highway. Slabs can be compacted to target mixture densities using loads that are equivalent to those of full-scale compaction equipment.
The CRT-RC2S and CRT-RC2SV are pneumatically powered and controlled by a programmable logic
controller (PLC) connected to an HMI which the operator can use to select the number of passes and
compaction load levels. Although the primary function is to produce slabs for wheel tracking tests, the
slabs can be sawn into beams or cored to provide specimens for a variety of other tests. Users have
compacted hot asphaltic materials over stress absorbing membrane interlayers (SAMIs) on a base of
cracked concrete in order to assess the effectiveness of the SAMI by using shear or bending tests.
