Product Details

Asphalt Apparatus Automatic Wheel Track Tester Bitumen Rutting Test Machine

Summary

This wheel track tester is designed and made as per industrial standard T0719-2011 Wheel Track Test for Bituminous Materials in JTG E20-2011 Standard Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering. It is used to determine the wheel track resistance property of bituminous mixtures under high temperature condition(Immersed in water or not immersed in water).

I. Main technical features

1. This rutting tester adopts PWM temperature control. It can control :

⑴Water temperature in chamber during water immersed wheel track test

⑵ Ambient temperature of constant temperature chamber at a time.

2. The constant temperature chamber adopts outside circulatory heating mode. The uniformity and stability is good. No overshoots.

3. This wheel track test machine shows time- displacement curves and time- temperature curves during a test.

4. It equips an absolute temperature sensor. No temperature drift in a long time test.

5. The mechanical structure adopts wheel movement mode.

6. One wheel tester. It can determine both water immersion test or no water immersion test.
