The WheelTracker is manufactured out of about 93 percent stainless steel and it is used to test the wearability and water damage potential of asphalt mixes.
By simulating roadway conditions in a controlled environment and using a Linear Value Displacement Transducer to measure deformation of a sample over 11 equally spaced points at 158 lbs. of pressure (adjustable).
The Balluff Linear Variable Differential Transformer (LVDT) transducer supplies robust and accurate rut depth measurements. It works with the index plate to generate root-mean-square error (RMSE) values significantly below AASHTO standards for rut depth measurements.
The Index Plate provides laser accuracy for location of rut depth measurements and works with the Balluff LVDT transducer to generate RMSE values significantly below AASHTO standards for rut depth Measurement
The WheelTracker has a variable-speed motor and slider-crank mechanism that generates RMSE values significantly below AASHTO standards for sinusoidal motion, and lasts longer than a Scotch yoke mechanism.
Temperature control allows you to test at a variety of temperatures, from 77oF to 158oF (25oC to 70oC).
TroxLiftTM provides a compact lifting method and is easy to use. TroxSafeTM stops the machine quickly to prevent injury, and rapidly resets to allow testing to continue.
