AUTO LIFT ARM ECO

WHEEL TRACKER

The Auto Lift Arm ECO Wheel Tracker saves energy, is space-efficient, and can double daily testing output. Wheel tracking assesses the rutting resistance of asphaltic materials under conditions simulating traffic. A loaded wheel moves across a sample under specified load, speed, and temperature while rut development is continuously monitored. Test specimens may be slabs produced with a laboratory compactor or 200mm Ø highway cores. The CRT-WTECO-A™ wheel tracker performs both procedures A and B specified for the small-scale device in EN 12697-22. Procedure A requires six specimens. Procedure B needs only two, but rut depth must be measured at more points along the longitudinal profile and tests run longer. To accelerate testing, the CRT-WTECO-A™ is designed to test two specimens in a single working day via a pre-programmable lift-arm mechanism (European Community registered design #: 001699042).

Wheel Load (N) 700N Mould Dimensions (mm) 305 x 305mm Wheel Speed 26.5 cycles per minute Slab Thickness (mm) 35 to 100mm Rut Depth Transducer Range (mm) 50mm PC Included

KEY FEATURES

• Tests materials for roads with axle loads up to 13 tonnes • Fully programmable automated lift arm, enables up to twice the normal test throughput • Automated pre programmable sample conditioning • Small and compact for maximum energy efficiency • Integral temperature controlled cabinet with fully glazed doors • Ambient to 62°C • Specimens compacted with the Cooper Technology Roller Compactor can be transferred directly to the wheel tracker without de-moulding • User-friendly Windows™ software • Supplied with UKAS accredited calibration certification • CE marked SOFTWARE • User friendly, intuitive and reliable Windows™ software developed using LabVIEW™ • Programmable for auto start, enabling up to double daily testing output • Programmable sample conditioning to enable test to start prior to the working day • Software automatically starts the wheel tracker, maintaining the speed at the specified 26.5 cycles per minute • Measures rut depth and sample temperature automatically at regular intervals • The rut profile is captured automatically by the software and analysed to calculate the rut depth • A continuously updated on-screen graph shows rut depth versus time, along with the rut profile and temperature • Software stops the wheel tracker on completion of a test and prints a test report if required • Stored test data can be analysed and compared with other test data utilising a spreadsheet package • Utilities are included for transducer check, diagnostic routines and RTD calibration • USB PC link • Excel import data output
