Adopt automatic temperature control system with air circulation, and a constant temperature water tank inside, which can be used for water immersion rutting test. The cabinet heating adopts a constant temperature PTC heating unit, which is safer and more reliable. The temperature of the heated airflow. Highly limited, the flow rate is increased, the internal temperature uniformity of the box is increased This machine has automatic temperature control, automatic timing, real-time display of the displacement of the rut, and automaticaly records the displacement curve and prints reports. Simultaneously display the time and displacement, time and temperature change curves during the test, which provides a practical basis for scientific research units studying the rutting characteristics of asphalt mixtures. Adopt absolute temperature sensor to colect temperature, and there is no temperature drift in long-term test (eliminate the influence of temperature drift of general thermoelectric corner temperature sensor on test data for a long time). Temperature control adopts PWM modulation control, high temperature stability, to ensure no overshoot. Adopt high-precision A/D (16-bit) and D/A (16-bit) modules to ensure the accuracy and resolution of displacement measurement and temperature control
