Standard Roller Compactors

The Roller Compactor CRT-RC2S is pneumatically powered and controlled by a fully programmable logic controller (PLC) connected to an HMI (Human Machine Interface) which the operator can use to select the number of passes and compaction load levels (up to 6). 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. A vibration option is available to fully simulate on-site vibratory rollers.
