Optimisation of repeatability and productivity through the removal of 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 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. 500x180mm slabs are usually wheel tracked in the Large Wheel Tracker CRT-WTENLD, whilst 600x400mm slabs are normally cut to produce trapezoidal or prismatic specimens for fatigue, modulus tests and Duriez test. See what CRT-RCENLD-III asphalt compaction configurations Cooper suggests.
