ASPHALT PAVEMENT THERMAL
TESTING SYSTEM (TSRST)
Optimise
low
temperature
performance
of
asphaltic
concrete
mixtures. Complies with AASHTO TP10 and EN 12697-46
The
Thermal
Stress
Restrained
Specimen
Test
(TSRST)
is
used
to
determine
the
low
temperature
cracking
susceptibility
of
asphalt
concrete.
In
the
early
1990s
the
TSRST
was
developed
by
OEM
with
Oregon
State
University
(OSU)
as
part
of
the
Strategic
Highway
Research
Program.
The
test
method
became
AASHTO
TP10.
The
TSRST
test
has
also
been
included
as
one
of
the
tests
within
EN12697-46.
OEM-Cooper
have
developed
the
TSRST
device
to
perform
tests
included
in
this
standard.
Now
as
a
multi-purpose
low
temperature
testing
machine,
the
TSRST
has
been
renamed
the
Asphalt
Pavement Thermal Testing System (APTTS).
With
over
20
years
of
experience,
and
as
the
original
developers
of
the
TSRST OEM-Cooper are the recognized world experts in the field.
MAIN FEATURES
•
Cool or heat an asphaltic concrete specimen at a constant temperature
•
Simulate actual field conditions with user programmable temperature profiles
•
Perform cyclic temperature testing
•
Minimises radial and/or transverse forces with dual clevis and rod end assemblies
KEY USES
•
Determines
the
failure
characteristics
of
Asphaltic
Concrete
(AC)
specimens
when
cooled
below
freezing
according
to
a
user
defined
temperature profile
•
Evaluates low temperature performance of field cores from existing roads
•
Test laboratory compacted cores of new or experimental mixes
•
Demonstrates the effects on low temperature performance of modified binders and from adding modified to standard binders
SOFTWARE
•
User friendly, intuitive and reliable Windows™ software developed using LabVIEW™.
