I.Summary
 SYD-0719 Automatic Wheel Rutting Tester is designed and made as per T0719 2011 in the Industry Standard  JTG E20-2011 Specification and Test Methods of Bitumen and Bituminous Mixture for High Engineering .
It is mainly used to determine the resistance to rutting of bituminous mixture at high temperature. 
It can also be used for high temperature stability of asphalt mixture test on site.
 
 
II. The main technical characteristics
1.The instrument is the floor structure, it adopts PC computer control technology, automatic temperature control automatic timing test process ,real-time display rut of displacement, and automatically record the displacement curve, print statements.
2.When test also showed time and displacement of time and temperature change curve, for studying the characteristics of asphalt mixture rut scientific research units to provide practical basis.
3.The instrument can test with the temperature of 45 ¡æ~ 85¡æ, wheel rutting test under pressure of 0.7 MPa, standard test time is 60 min.
4.Using absolute temperature sensor acquisition, PWM modulation type temperature control, high temperature stability, no overshoot, long test no temperature drift,(put an end to the general thermocouple temperature sensor for a long time work temperature drift effects on test data)
5.With high precision A/D (16) D/A module (16), to ensure that the displacement measurement and temperature control accuracy and resolution of the constant temperature box adopts outer circulation heating mode, uniform temperature field.
