Solid machine frame


Precision and reliability guaranteed


Vibration option to simulate conditions in-situ

Integrated hydraulic control

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. 

  • Steel wheeled roller segments 
  • Solid machine frame 
  • Optional heated head for reducing mixture sticking to roller during compaction 
  • Compaction head option: of 15.7/12.6 x 10.2 inch (400/320 x 260mm) and 15.7/12 x 12 inch (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) (equivalent to largest on-site static rollers) 
  • Speed control 
  • HMI for operator selection of number of passes 
  • Vibrating roller and heated head option to simulate on-site vibratory rollers.
