Application: The Wheel Tracking Device measures
rutting resistance ability of asphalt mixture against
high temperature and supplemental tests of asphalt
 mixture design.
Parameter:
1.Rolling distance of the grinding wheel:42В±1times/ min
2.Movement distance of the testing trolley :230В±10mm
3.Specimen mould size:300Г—300Г—50mm
4.Measuring range of the displacement:0-40mm
5.Wheel rutting test time:1-999min
6.Constant temperature controlling range: room
