The Auto Lift Arm ECO Wheel Tracker saves energy, is space efficient and can double daily testing output
Wheel tracking is used to assess the resistance to rutting of asphaltic materials under conditions which simulate the effect of traffic. A loaded wheel tracks a sample under specified conditions of load, speed and temperature while the development of the rut is monitored continuously during the test. Test specimens can be either slabs prepared with a laboratory compactor or 200mm Ø cores cut from the highway.
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 that six specimens are tested. For procedure B only two specimens need to be tested, but rut depth must be measured at more points along the longitudinal rut profile and the tests are longer. To speed up the testing process the CRT-WTECO-A™ was designed to test two specimens within one working day via a pre-programmable unique lift arm mechanism (European Community registered design #: 001699042).
