PRECISION UNBOUND
MATERIAL ANALYSER – LARGE
The
Precision
Unbound
Material
Analyser
(PUMA)
is
a
new
type
of
laboratory
test
equipment
designed
to
fill
the
gap
between
expensive
and
complex
laboratory
tools
(such
as
triaxial
cells)
and
more
empirical
methods
(such
as
the
California
Bearing
Ratio
test).
It
is
designed
to
generate realistic values of modulus for use in road pavement design.
The
PUMA
can
be
used
to
test
unbound,
hydraulically
bound
and
asphaltic
materials.
It
has
been
designed
as
a
low
cost,
easy
to
use
and
practical
tool,
but
one
which
is
capable
of
generating
scientifically
meaningful
data
(Modulus
and
Resistance
to
Permanent
Deformation),
for
use
in
road
pavement
design.
It
can
be
used
to
test
specimens
made
from
granular
material,
soil
or
lightly
stabilised
material
etc,
with
a
maximum
particle
size
of 63mm.
KEY FEATURES
The
PUMA
is
proposed
as
a
direct
equivalent
to
the
Springbox,
with
the
advantage
that
initial
stress
conditions
can
be
accurately
controlled.
It
is
a
simple
test,
suited
to
generic
specification,
that
holds
the
promise
of
increased
confidence
in
pavement
foundation
design,
particularly
in
cases
where
favourable
weather
conditions
during
construction
result
in
unrepresentatively
high
Dynamic
Plate
Test
(DPT)
values,
or
in
cases
where stabilised soils or cold-mix asphalt are employed.
•
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 63mm
•
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
SYSTEM ELEMENTS
The CRT-PUMA-L is comprised of:
•
Two adjustable steel bands
•
Mould wall segments (eight pieces of hardened steel)
•
Base plate
•
Base
•
Platen
•
Rubber lining strips
•
T-sections (placed between mould wall segments to prevent particle escape)
•
Strain Gauged Measurement Band
•
Compaction jacket
•

•
2x LVDT ± 7.5mm range
•
LVDT frame
•
O-ring
•
Data acquisition system
