Abstract :
Increasing the quality of hot asphalt mixtures
is continuously carried out with various kinds of
experiments, one of which is by mixing additives in the
form of polymers. LDPE (Low Density Polyethylene) and
HDPE (High Density Polyethylene) are polyethylene
chain structures that can be found in daily life, such as the
form of plastic food wrappers, plastic bags and shopping
bags. This study aims to compare the effect of using LDPE
and HDPE plastic waste without the use of plastic waste
on the characteristics of the hot asphalt mixture Marshall
Asphalt Concrete Wearing Course (AC-WC). After
obtaining the optimum asphalt content at 5.6%, the
optimum plastic content for LDPE is 2.1% and HDPE is
2.4%. The results of the Marshall characteristic test
showed that the stability value of the AC-WC hot asphalt
mixture with the addition of HDPE plastic waste was
higher, that was 1216 kg, compared to the addition of
LDPE plastic which was 1130 kg and without the addition
of 1211 kg plastic. The value of flow in the addition of
LDPE plastic had the highest value, 3.53 mm compared to
the addition of HDPE plastic, 3.27 mm and without the
addition of plastic which had the lowest value, 3.20 mm.
From the results of residual stability testing with IKS
(Residual Strength Index), the addition of LDPE plastic
