SLURRY SURFACING
COHESION TESTER – AUTOMATIC
The
Slurry
Surfacing
Cohesion
Tester
–
Automatic
(CRT-SSCT-A)
is
a
robust,
easy-to-use
machine
designed
to
determine
the
minimum
cohesion
of
slurry
surfacing
mixes,
which
is
essential
for
set
time
and
trafficability
assessment.
It
operates
per
EN
12274-4,
taking
torque
measurements
at
intervals
to
track
cohesion
build-up.
Unlike
manual
methods,
it
eliminates
operator-dependent
errors
and
provides
consistent, reliable results.
The
CRT-SSCT-A
fully
automates
both
force
application
and
rotation,
ensuring
precise
adherence
to
rotation
angles
and
timing
specified
by
standards.
A
high-accuracy
torque
cell
placed
directly
behind
the
rubber
foot
measures
torque
free
from
seal
friction
errors,
while
a
digital
peak-hold
display
ensures
repeatable
readings.
Its
stepper
motor
delivers
consistent
performance,
testing
multiple
samples
efficiently.
Adaptable
to
ASTM
D3910,
the
CRT-SSCT-A
provides
a
versatile,
reliable
solution
for
quality
control
and
research,
improving
accuracy,
consistency,
and
confidence
in
slurry
surfacing
applications.
DESCRIPTION
Slurry
Surfacing
Cohesion
Tester
–
Automatic
is
an
advanced,
easy
to
use
and
robust
machine
to
determine
the
minimum
cohesion
of
a
slurry
surfacing mix
The
slurry
surfacing
cohesion
tester
is
used
to
determine
the
minimum
cohesion
of
a
slurry
surfacing
mix
which
enables
the
set
time
and
trafficability
time
to
be
determined.
According
to
EN
12274-4,
torque
measurements
are
taken
on
five
samples
of
the
same
slurry
mix
at
suitable
intervals after casting. This gives a picture of the Cohesion Build Up in the slurry.
Historically
EN
12274-4
was
carried
out
with
manual
equipment
with
which
torque
was
generated
by
hand
using
a
torque
screwdriver.
The
requirement
of
the
standard
is
to
apply
a
rotation
of
between
90°
and
120°
in
0.5
to
0.7
seconds.
This
gives
not
only
a
wide
range
of
conditions,
but
also
a
very
difficult
set
of
conditions
to
achieve
and
monitor,
and
has
inevitably
led
to
results
which
have
a
high
dependence
on
the
operator.
Coupled
with
this
there
is
also
a
source
of
inaccuracy
in
the
way
the
torque
is
measured.
As
the
torque
meter
is
placed
at
the
rear
of
the
through
rod
cylinder
the
friction
in
the
seals
of
the
actuator
will
oppose
the
rotational
motion
and
thus
an
additional
torque
is
generated
which
shows
up
in
the
torque
reading.
The
friction
in
the
seals
is
also
likely
to
change
as
the
machine
ages
and
thus
results
on
a
nominally
similar sample can be different from one day to the next.
