Summary

   The instrument is designed and made as per T0719-2011 “Bituminous Mixtures Wheel-Track Test” in the Industry Standard of People’s Republic of China JTG E20-2011 Standard Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering. It is suitable to determine the wheel-track against capability of bituminous mixtures in high temperature (Immersion and not immersion). It also can use as the assistant tester of match design for bituminous mixtures .And can be used to do the determination of the stability of bituminous mixtures in high temperature on site .

 

I. Main technical characteristics

1.The instrument can automatic control temperature, automatic generate, save test results; And it is convenient to call
   history data and print out test report.

2.The instrument adopts absolute temperature sensor, long time no temperature drift test. Wide temperature controlling
   range, high accuracy, good stability.

3.The test machine and constant temperature adopts a kind of all-in-one machine, and inner box adopts air circulation
   and it has high temperature controlling accuracy .Stable operation and no noise.

4.The instrument adopts high accuracy displacement sensor, The precision is more than +0.05mm .The data resolution is
   high and the speed is fast.

5.The computer and touch-screen can be controlled independently.

6.It can be done immersion test .It can do two tests and preheat six samples at the same time.

 

II. Advantages of the software

1.Non standard function: set time and temperature at random.

2.Real-time display time, displacement deformation and time, temperature curve.

3.It can display compaction time and times.

4.It can automatic calculate and print out wheel-track stability value.

5.The software can calibrate correctly to displacement and temperature sensor.

6.The device has self-diagnostic function, and display fault code to ensure the device can operate stability.

7.It can make the multi acquisition to the deformation and can improve the consistence of the test results.
