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.
