Reclaimed asphalt pavement (RAP) is produced in signiicant amounts. Nevertheless,
the
use of RAP is limited due to
the
absence of laboratory
and ield performance
data.
This research
addresses
laboratory
and ield tests
to
evaluate
the
use
of
RAP and various
adapted
mixtures
in constructions
such
as road-bed
layers
and
substitution
layers.
Modiied proctor
compaction,
California
bearing
ratio,
unconined
compression
test,
and static
plate loading tests
have
been conducted on RAP,
a
mixture
of RAP and crushed
stone
aggregates
(CSA),
and RAP stabilized
with
cement
to
satisfy the
objective.
Results
have
shown
that
100% RAP material
is suitable
for
use as a sub-base material.
The ability of RAP material
to
be utilized as
a
cement-treated
base
layer
is
more
pronounced
when
it
is
stabilized
with
cement
(100%
RAP
+
8%
and 10% cement). Utilization of 100% RAP stabilized
with
cement
has
been demonstrated
to
be economical in comparison
with
100% CSA
without
cement.
Finally,
RAP material
has shown
good performance
as a substitution
layer. |
