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. This compactor is hydraulically powered and controlled by a programmable logic controller (PLC) connected to an HMI (Human Machine Interface), which the operator can use to select the number of passes A manual pressure control is adjusted to set the required load. The main function of the Compact Steel Roller is to produce slabs for beam fatigue and wheel tracking tests.
- Versatile with various steel wheeled roller segments available
- Optional heated head for reducing mixture sticking to roller during compaction
- Optional vibrating roller option to simulate on-site vibratory rollers
- Compaction head option: of 15 7/12 6 x 10 2"(400/320 x 260mm) and 15 7/12 x 12" 400/305 x 305mm) slabs
- Slab depth from 1 6 to 3 9 inch (40 to 100 mm)
- Slabs can be used as wheel-tracking specimens, and cored to make indirect tensile test specimens or cut into beams for 4-Point Bending Test
- Roller Compactor molds will fit Cox/Cooper Wheel Trackers so that compacted slabs can be wheel-tracked without de-molding
- Maximum compaction load of 30kN (6750lbf) which is equivalent to largest on-site static rollers
- Speed can be controlled by user
- HMI for operator selection of number of passes
- Solid machine frame on height adjustable feet with enclosed transparent guarding with fully compliant safety interlock
