PRECISION UNBOUND
MATERIAL ANALYSER
The
Precision
Unbound
Material
Analyser
(PUMA)
is
a
new
laboratory
device
designed
to
bridge
the
gap
between
expensive,
complex
tools
(such
as
triaxial
cells)
and
empirical
methods
(like
the
California
Bearing
Ratio
test).
It
provides
realistic
modulus
values
for
road
pavement design.
The
PUMA
tests
unbound,
hydraulically
bound,
and
asphaltic
materials.
It
is
low-cost,
easy
to
use,
and
capable
of
generating
scientifically
meaningful
data
(Modulus
and
Resistance
to
Permanent
Deformation).
It
can
test
specimens
of
granular
material,
soil,
or
lightly
stabilised
material
with
a
maximum
particle
size
of
31.5
mm.
Proposed
as
a
direct
equivalent
to
the
Springbox,
it
offers
improved
control
of
initial
stress
conditions.
This
simple,
specification-friendly
test
supports
greater
confidence
in
pavement
foundation
design,
especially
where
favourable
construction
weather
yields
unrepresentatively
high
Dynamic
Plate
Test
values
or
where
stabilised
soils
or cold-mix asphalt are used.
KEY FEATURES
•
Designed for use within a UTM loading frame
•
Compatible with existing loading systems currently used for asphalt testing
•
Compaction can be carried out using existing vibrating hammer equipment
•
Flexibility to alter stress conditions (vertical and horizontal) and the number of load cycles if desired
•
Possibility to carry out the test directly under DPT equipment in order to simulate as closely as possible the likely in-situ value
•
Equipment is applicable to all unbound materials with particle size up to 31.5mm
•
Suitable for tests on hydraulically bound materials
KEY USES
•
Determination
of
stiffness
modulus
under
different
stress
conditions,
allowing
pavement
design
to
be
more
scientifically
based
than
is
possible when relying on an assumed relationship to an in-situ DPT value
•
Measurement
of
rate
of
increase
of
permanent
deformation,
which
can
be
directly
related
to
design
against
rutting,
applicable
to
relatively
thinly surfaced roads
•
Tests cold mix asphalt
Software
•
User friendly, intuitive and reliable Windows™ software developed using LabVIEW™
•
The software records the following to text file for compatibility with common spreadsheet software such as Microsoft Excel:
•
Axial Stress
•
Axial Strain
•
Radial (Confining) Stress
•
Radial Strain
•
Stiffness Modulus
•
Poisson’s Ratio
Note:
Software supplied only when PUMA is ordered with our UTM.
