Advanced integrated hydraulic control, precision and reliability guaranteed
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-RC-H2 is hydraulically powered and controlled by a programmable logic controller (PLC) connected to a HMI which the operator can use to select the number of passes. A manual pressure control is adjusted to set the required load. Its main function is to produce slabs for wheel tracking 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.
