STAND ALONE FOUR POINT
BENDING BEAM MACHINE
A
low
cost,
accurate
beam
testing
system
which
facilitates
the
rapid
throughput of modulus and fatigue tests.
Bending
tests
are
widely
used
for
measuring
the
stiffness
modulus
and
assessing
the
fatigue
resistance
of
asphaltic
paving
materials.The
specimen
is
a
prismatic
beam
which
is
subjected
to
sinusoidal
loading
in
either
the
controlled strain or controlled stress modes.
The
SA4PT
uses
advanced
servo
pneumatic
technology
and
a
high-speed
digital
data
acquisition
and
control
system
together
with
user-friendly
software.
During
testing
both
graphical
and
tabular
data
are
displayed
on
screen
and
test
data
is
stored
to
disc
in
Microsoft
Excel™
compatible
format.
The
clamps
are
at
118.5mm
centres
(the
distance
between
the
outer
clamps
is
335.6mm
(14
inches)
according
to
AASHTO
specifications
*
but
the
height
and width of the beam can be varied).
*
Tests
on
beams
containing
aggregates
greater
than
20mm
are
not
strictly
in
accordance
with
annex
D
of
EN
12697-24
which
states
that
this
non-compliance
should be explicitly mentioned in the test report.
KEY FEATURES
•
Fully complies with international standards
•
Utilizes a super low-friction actuator and high-performance ceramic spool servo-valve
•
On-specimen and floating beam measurement system
•
The market leader in performance (participant 13) as determined in the international fatigue Round Robin organized by TU Delft
•
Very low compliance test frame
•
Sinusoidal controlled strain or controlled stress fatigue test modes
•
Constant torque motorized specimen clamping to eliminate errors due to localized beam indentation
•
User friendly software for determination of fatigue resistance and stiffness modulus
•
Supplied with a certificate of calibration
•
Manufactured in the United Kingdom
KEY USES
•
Mix design
•
End product specification
•
Assessment of new materials
SOFTWARE
•
User friendly, intuitive and reliable Windows™ software
•
Specifically written to meet EN 12697-24 Annex D and EN 12697-26 Annex B
•
The user interface can be translated into the user’s preferred language – please enquire
•
Stored test data can be analysed and compared with other test data utilising a spreadsheet package
•
Utilities
are
included
for
curve
fitting
of
acquired
data;
testing
of
system’s
inputs
and
outputs;
phase
correction
and
a
transducer
database
for storing calibration factors
