LARGE ROLLER COMPACTOR

PNEUMATIC TYRED ROLLER

Optimisation of repeatability and productivity through the automation of human interface Roller compaction is the laboratory method that most closely simulates on- site compaction. The machine can be configured to operate with a single wheel or twin wheels depending on the mould size. The wheels track the surface in overlapping wheel-paths using sequences specified in EN 12697- 33 or custom sequences designed by the user. The base of the mould is incrementally raised by a precision jacking system and the system is tracked to keep it level with the top of the mould. Compacted slabs can be from 50 to 150mm thick. 500 x 180mm slabs are usually wheel tracked in the Cooper Technology Large Wheel Tracker, whilst 600 x 400mm slabs are normally cut to produce trapezoidal or prismatic specimens for fatigue, modulus tests and Duriez test.

Maximum Wheel Load 5kN Single wheel, 10kN Dual wheel Mould Dimensions (mm) 500 x 180, 600 x 400mm (others available) Wheel Speed (mm/s) 200 to 500mm/s Slab Thickness 50, 100, 150mm (others available) Compressed Air (bar) 7-10 bar @ 100 L/min PC Included
