WHEEL TRACKER LARGE DEVICE
FAST, ACCURATE COMPUTERISED EVALUATION
Wheel
tracking
evaluates
asphalt’s
rutting
resistance
by
testing
two
specimens
under
controlled
load,
speed,
temperature,
and
wheel
tracking
conditions,
with
rut
depth
monitored
throughout.
The
CRT-
WTENLD
improves
on
earlier
testers
using
an
advanced
instrumented
measurement
system
and
computerised
control
for
faster,
more
accurate data acquisition.
Wheel
tracking
assesses
how
asphalt
resists
rutting
by
simulating
traffic
conditions.
The
device
tests
two
large
specimens
simultaneously,
applying
controlled
load,
speed,
temperature,
and
pneumatic-tyred
wheel
tracking
while
continuously
monitoring
rut
development.
Specimens
are
easily
inserted
and
removed
with
an
Easy-load
system.
The
Wheel
Tracker
Large
Device
CRT-WTENLD
advances
beyond
the
French
Pavement
Rutting
Tester
by
incorporating
a
unique
instrumented
measurement
system
tied
directly
to
data
acquisition,
providing
greater
efficiency
and
accuracy.
All
test
conditions
and
data
collection
are
managed
through
Windows™-based
software via a high-speed digital interface and signal conditioning system.

MAIN FEATURES
Optimisation of the wheel tracking test time and result accuracy through computerised control.
Wheel
tracking
is
used
to
assess
the
resistance
to
rutting
of
asphaltic
materials
under
conditions
which
simulate
the
effect
of
traffic.
In
this
machine,
two
500x180mm
specimens
are
tested
simultaneously
by
tracking
with
wheels
fitted
with
pneumatic
tyres
under
specified
conditions
of
load,
speed
and
temperature
while
the
development
of
the
rut
profile
is
monitored
at
specified
intervals
during
the
test.
The
moulded
specimens are inserted and removed from the wheel tracker using an Easy-load system.
The
Wheel
Tracker
Large
Device
CRT-WTENLD
supersedes
the
French
Pavement
Rutting
Tester
by
using
a
unique
instrumented
measurement
device,
linked
to
the
data
acquisition,
to
measure
the
development
of
rutting
during
testing.
It
allows
extreme
efficiency
compared
to
any
other
type
of
devices
of
its
type.
The
test
procedure
and
conditions
are
controlled
and
data
acquired
using
Windows™
software
running
on
a
host
computer via a high speed digital interface and signal conditioning system.
We have recently innovated Wheel Tracker Large Device and added two new exciting features:
Temperature recording and display
This
new
functionality
in
the
software
allows
the
operator
to
observe
in
real
time
a
graph
of
the
temperature
as
a
function
of
time
for
each
of
the
4
probes
(air
and
sample
temperature
for
each
side
of
the
machine)
from
the
start
of
the
conditioning
period
until
the
end
of
the
main
test.
Temperature
data
are
also
stored
in
a
file
for
record
keeping
and
analysis.
Data
are
recorded
at
user-defined
intervals,
with
a
minimum
interval
of 30 seconds.
3-colour light system indicating the status of the computer
Controlling
your
time
in
a
very
active
test
lab
environment
divided
over
various
tests
and
test
devices
is
not
always
easy.
We
have
incorporated
a
beacon
on
our
Large
Wheel
Tracker
to
make
life
easier
for
laboratory
operators.
It
clearly
indicates
the
status
of
the
test
at
a
glance
across
the
laboratory.
This beacon is essentially an efficient 3-color light system which works as follows:
•
Red – Undergoing test cycles
•
Amber – Take measurements reading
•
Green – Test completed – machine stopped
This function allows the operator to work more effectively.
