Automatic Rutting Test Single Wheel Track Machine for Asphalt or Bitumen
Overview
Wheel tracking machine for rutting ability of asphalt & asphalt-concrete materials in high temperature.
Features
1. It can be used as standard test.
2. Automatic temperature control, automatic generation and save the test results, Convenient call history data,
output test report.
3. Point to point data collection: the position of the upper and lower machine control system to ensure the deformation repetitive gathering space.
4. High resolution data acquisition, high speed.
5. Wide temperature range, high precision, good stability, PWM modulation method is adopted to improve the temperature PID control, to ensure that the temperature without overshoot.
6. Using absolute temperature sensor to collect temperature, test without temperature drift for a long time (to eliminate the general thermocouple temperature sensor working temperature drift for a long time) on the test data.
7. Air circulation in the oven, high temperature control precision.
8. Displacement sensor with high precision, under the big range accuracy is less than ±0.05 mm.
9. Equipped with constant temperature box integration structure, easy to move.
10. Smooth operation, no noisy.
11. Computer control, simple and convenient operation..
12. Can preheat 3 test specimens at the same time.
13. Small size, occupying only 1.52m × 0.77 m.
Advantages of software
1. Non-standard function: time and temperature can be set arbitrarily.
2. Display time-displacement deformation and time-temperature curve in real time.
3. can display rolling time and rolling times.
4. Automatically calculate and print the rut stability value.
5. The software can calibrate the displacement sensor and temperature sensor accurately.
6. The device has a self-diagnostic function and can display fault codes to ensure the reliable operation of the device.
7. Collect multiple points of deformation to improve the consistency of test results.
