This product is suitable for measuring the high temperature (immersion or non-immersion) anti-rutting ability of asphalt mixture, and it is used for the high temperature (immersion or non-immersion) stability test of asphalt mixture ratio design.
The instrument has been sold domestically, with stable and reliable quality and excellent performance, and has been widely praised. At the same time, it has provided a large amount of real and effective data for the Ministry of Communications to compile the domestic industry standards for this instrument.

1. The instrument automatically controls the temperature, automatically generates and saves the experimental results, and it's convenient for calling historical data and outputting experimental reports.
2. Point-to-point data collection: use the upper computer and the lower computer measurement and control system to ensure the repeatability of deformation collection space
3. High resolution and fast data acquisition
4. Use PID modulation method for temperature PID control to ensure that the temperature has no overshoot
5. The temperature sensor is used to collect the temperature, and there is no temperature drift in the long-term experiment (it eliminates the influence of the general thermocouple temperature sensor's long-term working temperature drift on the experimental data)
6. Large air circulation is adopted in the box, and the temperature control accuracy is high
7. Using high-precision displacement sensor, the accuracy is better than ±0.05mm in a large range
8. The integrated structure of the testing machine and the incubator can be easily moved
9. Smooth operation, no noise
