UNIVERSAL TESTING MACHINE
SERVO PNEUMATIC
Rapid
determination
of
modulus,
permanent
deformation
and
fatigue
of
bituminous
mixtures
using
cylindrical
specimens
that
are
cored
from the highway or prepared in the laboratory
This
machine
is
a
development
of
the
NAT
which
was
developed
by
Keith
Cooper
and
Professor
Steven
Brown
at
the
University
of
Nottingham.
The
use
of
a
high
precision
servo-pneumatic
valve
in
conjunction
with
a
low-
friction
actuator
and
sophisticated
data
acquisition
and
control,
results
in
a
performance that is equal to many servo-hydraulic systems.
Accurate,
digitally
generated
waveforms
are
applied
by
the
actuator
producing
repeatable
stress
variations
in
test
specimens
that
are
simulative
of
those
in
a
road
pavement
due
to
moving
traffic.
The
actuator
is
double-
acting
allowing
both
compressive
and
tensile
forces
to
be
applied.
A
triaxial
cell
system
is
available
for
the
measurement
of
the
resilient
modulus
of
unbound materials.
KEY FEATURES
•
Low cost dynamic loading universal test system ideally suited to testing asphalt and unbound granular materials
•
Double acting low friction actuator with integral stroke transducer
•
High performance ceramic spool servo-valve
•
High quality stainless steel frame
•
Issued with certificate of calibration for EN 12697-24; EN 12697-25, EN 12697-26
•
Accessories available to perform a range of standard and non standard test methods
KEY USES
•
Assessment of resistance to permanent deformation (rutting)
•
Measurement of stiffness modulus
•
Assessment of resistance to fatigue cracking
•
Resilient modulus of unbound materials
•
Mix design
CONTROL SYSTEM AND SOFTWARE

user
selected
frequencies
and
data
collection
rates.
Stored
test
data
can
be
imported
into a spreadsheet package to be analysed by the user. Utilities are included for transducer check, diagnostic routines and calibration.
