Hamburg Wheel Tracker

TBTACZ-HWT Hamburg Wheel Tracker Determination of rutting and water sensitivity of Hot Mix Asphalt (HMA), permanent deformation of asphalt mixture under moving load, by measuring the rutting depth of asphalt mixture and the number of loading times at failure, to determine due to aggregate structure Insufficient binder strength or early damage caused by water damage can be used to evaluate the effect of water damage on asphalt mixtures because the specimens can be immersed in water at a certain temperature throughout the test.

1. Computer control for easy operation;

2. High precision displacement sensor with better than ±0.01mm accuracy under large range;

3. Fully automatic for temperature control, wheels moving, generation and storage of test results;

4. Absolute temperature sensor to collect temperature, with wide temperature control range, high precision and good stability;

5. PWM modulation mode for temperature PID control to ensure no overshoot of temperature;

6. Linear modulation of temperature and displacement sensor can ensure linearity within full scale;

7. The data collection system can collect 11 points in the area of 210mm symmetrical to the center of the test mold to obtain the average deformation, which is used as deformation value when calculating the test results;

8. Stop tests by stopping according to the number of laps or stopping OR according to the depth of the rut;

9. Using an open working platform, the test wheel can be lifted automatically, which is convenient for installation and removal of the test mold;

10. High-quality rigid stainless steel structure.
