Wessex Engineering manufacturers of civil engineering test equipment - pendulum tester, polished stone value, aggregate abrasion value Wessex Engineering S867 Dry Wheel Tracker Calculates a Tracking Rate for samples of asphalt wearing courses, which provides a measure of resistance to rutting. In many countries asphalt pavement surfaces deform in high temperature conditions, which results in a need to relay the surface. The Wheel Tracking test offers a simple and inexpensive method of predicting if such failure is likely to occur. A loaded wheel is run over an asphalt sample in a sealed and insulated cabinet for 45 minutes. A specially designed computer program controls the operation of the machine, and records rut depth, temperature and elapsed tome during the test.
Comprehensive data is recorded and reported about the test.
Wessex also make an Immersion Wheel Tracker and a Slab Compactor. This machine is computer controlled, using specialised software developed by Wessex Tracking Rates are calculated automatically, with comprehensive Test Reports. The machine has a compact well insulated cabinet, resulting in precise control of temperature.
