EVALUASI KINERJA CAMPURAN BETON ASPAL LAPIS AUS (AC-WC) MEMAKAI LIMBAH ABU-CPO SEBAGAI FILLER
ABSTRAK: Energy source for
crude palm oil making process are usually from fry up palm fiber and nut shell
for which produce ash as
residue. Those residualhave
never been optimally
used, thus this
study suggested to optimiseash of palm fiber and nut shell
asfiller for asphalt mix. This study aims to evaluate impact ofadding ash of
palm fiber and nut shell to asphalt mix performance in terms of it stability
and durability and also to compare
the performance of asphalt mixwith
and without ash of palm
fiber and nut
shell using Marshall method. This
study found that
stability of asphalt
mix with AB50%
and AS50% ash
of palm fiber
and nut shell has
likely increased and
after reaching its
maximum value, stability
has steadily decreased,
while its durability has
gradually decreased. The highest and lowest IKS were found at asphalt mix with
AB100% and AS100% respectively. KAO
has gradually risen
along with increase
of percentage of
ash of palm
fiber and nut shell (5,6% KAO for
AB100% and AB50% and AS50% and 5,8% KAO for AS100%). To conclude, this result
showed that asphalt mix with filler using ash of palm fiber and nut shellneeds
high concentrate asphalt in order to meet volumetric asphalt mix characteristic
and Marshall.
