Description
Summary
This instrument is designed and made as per industrial standard
T********1 Wheel Track Test for Bituminous Materials in JTG
E******1 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).
Main technical features
1. PWM temperature control. It can control ：
(1)Water temperature in chamber during water immersed wheel track
test
(2) 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. It 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.
