Gilsonite road construction and asphalt
Gilsonite
is
used
as a
performance-enhancing
agent
for
asphalt
mixes.
Gilsonite-modified
paving
mixes
achieve
higher
PG
grades
and
incorporate
perfectly
into
the
asphalt
blend
with
no
need
for
high
shear
milling
as
is
the
case
with
many
other
modifiers.
Gilsonite
can
partially
or
totally
replace,
or
complement,
the
use
of
SBS
polymers
in
modified
asphalts
at a
fraction
of
the
cost.
Gilsonite-modified
asphalts
have
higher
stability,
reduced
deformation,
reduced
temperature
susceptibility
and
increased
resistance
to
water
stripping
than
non-modified
asphalts.
Gilsonite
is
also
used
to
make
both
solvent-based
and
emulsion
pavement
sealers
with
superior

and

properties
Gilsonite for water proofing
Gilsonite
is
used
in
roofing
materials
primarily
as
an
agent
to
lower
the
penetration
of
petroleum
asphalt
without
aging
or
oxidizing
the
base
asphalt.
Lowering
the
penetration
of
the
base
asphalt
in
this
way
allows the
base
asphalt
to
maintain
some
of
its
flexibility
while
at
the
same
time
maximizing
the
asphalt's
ability
to
withstand
high
temperatures
without
softening.
Gilsonite
is
also
used
as a
modifier
to
reach
roofing specifications
when
air-blowing
facilities
are
not
available.Gilsonite
is
also
used
by a
number
of
manufacturers
producing
patching
materials
for
roofing.
Gilsonite
is
used
to
modify
the
patching
materials
and
is
distributed
in
containers
to
retail
customers.
Using
Gilsonite
as a
modifier
allows
the
product
to
remain
pliable
until
applied,
after
which
it
permanently
attaches
to
the
treated
surface
GILSONITE FOR
INK,PAINT
AND
COAT.
The
paint
applications,
Gilsonite
is
usually
used
in
combination
with
bitumen
(asphalt).
In
most
cases,
if
Gilsonite
is
used
alone,
the
final
paint
will
be
very
hard
and
brittle
after
drying.
If
normal
straight-run
bitumen
is
used
alone,
the
finished
paint
is
too
soft
and
tacky.
Therefore,
a
combination
of
Gilsonite
and
bitumen
is
used
to
achieve
the
desired
hardness
(penetration)
and
drying
time
of
the
finished
paint.
In
addition
to
imparting
hardness
to
the
paint,
Gilsonite
is
also
increasing
the
paints:
(1)
adhesion;
(2)
gloss;
(3)
chemical
resistance;
(4)
water
resistance;
and
(5)
body.
For
hardness,
Gilsonite
has
a

(0)
penetration

25°C;

sec.)
compared
to
the
60-70
pen,
80-100
pen
or
softer
bitumens
commonly
available
from
petroleum
companies
or
asphalt
manufacturers.
Approximately
90%
of
all
bitumen
is
used
for
road
construction
and
these
hardness
grades
are
acceptable
for
that
purpose.
However,
they
are
too
soft
by
themselves
for
the
manufacture
of
paint
and
surface
coatings
which
require
hardness
values
around
5
penetration
for
acceptable
paint
drying.
Paint
films
composed
of
bitumen
alone
are
tacky
if
the
penetration
is
more
than
10,
and
are
brittle
if
less
than
4.
Gilsonite for foundry
Sand
properties
with
Gilsonite
resin
are
equal
or
superior
to
sea
coal
at
significantly
lower
additive
levels.
Gilsonite
improves
sand
density,
water
requirements
and
strength
(green,
dry,
baked,
and
hot).
Gas
evolution
curves
show
that
Gilsonite

more
rapidly
than

Gilsonite
has
the

total volatiles
as

at
one-third
the
additive
level.
