DSHD-0719A Automatic Wheel Tracking Tester
I.Product standard
1) DSHD-0719A Automatic Wheel Tracking Tester is designed as per T0719 “Bituminous
Mixture Wheel Track Test” in the Industry Standard JTJ052 Specification and Test Methods
of Bitumen and Bituminous Mixture for Highway Engineering.
2) DSHD-0719A Automatic Wheel Tracking Tester is a research type,which can be used for
colleges and universities as well as scientific research institutes to make research on the
resistance to rutting of bituminous mixture at high temperature.
3) DSHD-0719A Automatic Wheel Tracking Tester can be applied to manufacturing
companies and construction companies to determine the resistance to rutting of bituminous
mixtures at high temperature.
II.Main characteristics
1. DSHD-0719A Automatic Wheel Tracking Tester can be connected to any computer
processing system using newly developed microprocessor controlling techniques by us.
2. DSHD-0719A Automatic Wheel Tracking Tester can make determination for two test
molds at the same time with water immersion or without water immersion. The constant
temperature case equipped with the instrument can preheat 7 piece of test mold. This saves
a lot of time.
3. DSHD 0719A Automatic Wheel Tracking Tester adopts PWM mode for temperature
control.The instrument can simultaneously control:
(1) Sample temperature;
(2) Water temperature in the water case during water immersion test;
(3) Temperature in the constant temperature case
4. The constant temperature case is heated using outer circulation mode. The heating source
connects with the case through pipes to form thermodynamic equilibrium, so the temperature
is uniform.
5. DSHD-0719A Automatic Wheel Tracking Tester can display time-displacement curve and
time-temperature curve at the same time. This provides experimental evidence on rutting
characteristics of bituminous mixture for scientific research institutes.
6. DSHD-0719A Automatic Wheel Tracking Tester adopts a absolute temperature sensor for
temperature collection, so there is no drift during long time test (this solves the problem of
common thermocouple that the effect of drift on test data during long time test).
7. DSHD-0719A Automatic Wheel Tracking Tester adopts high precision A/D (16 digits) and
D/A (16 digits) module to ensure good accuracy and high resolution for displacement
measurement and temperature control.
8. Equipped with software, DSHD-0719A Automatic Wheel Tracking Tester can preset
test time and test temperature as your requirements, and it can recall deflection values
of any test molds and show them in real time.
9. DSHD-0719A Automatic Wheel Tracking Tester adopts wheel moving mode as its
mechanical structure. This is the same as that of foreign products. The test data is close to
the real condition.
10. The thickness of test molds is in the range of 0~100mm. They can meet rutting test
requirements of different road surfaces.
