Abstract: Porous asphalt mixture has low stability but high permeability due to the cavities in the mixture. For this
reason, it is necessary to add other materials in order to increase the stability of pavement mixture. The
purpose of this study was to obtain the Marshall property value of the porous asphalt concrete mixture. This
study is also analyze the effect of plastic waste in the porous asphalt concrete mixture on the permeability
and properties of Marshall. This research used is the experimental method in the laboratory. The Optimum
Asphalt Content (KAO) made with asphalt content 4.5%; 5%; 5.5%; 6%; and 6.5% without variation of
plastic waste. Furthermore, it is also made by KAO and the addition of plastic waste by 0%; 5%, 10%, 15%,
20% and 25% and tested with Marshall test and permeability. The results of the research with 5,5% KA0,
that the addition of plastic waste in the porous asphalt mixture can increase the value of stability, flow, and
marshall quotient. with an average value of 25% plastic waste content of 1296.71 kg; 3.62 mm and 353.19
kg / mm. However, the VIM and permeability values decreased, respectively, with an average value 20.65%
and 0.188 cm / s. The mixture of porous asphalt with plastic waste, for all parameters Marshall satisfied the
specifications required by the Australian Asphalt Pavement Association (2004) for moderate traffic
1 INTRODUCTION
One of the pavement types currently being
developed as a cover layer is porous asphalt
concrete. This mixture has low stability but high
permeability of cavities in the mixture. For this
reason, it is necessary to add other materials to
increase the stability value of the pavement mixture
(Arlia, Sofyan, Renni, 2018). The porous asphalt
mixture also contains a large percentage of coarse
aggregate, a small percentage of fine aggregate, thus
providing a large air cavity that can drain water
from the surface into the soil. The large cavity
makes porous asphalt has a low stability value. To
increase stability, added materials are needed
(Supriyadi, 2018 dan Ghulam, 2017). The high
cavity content results in a larger oxidized asphalt
surface which reduces the ability of the binder to
maintain the aggregate position, therefore an asphalt
with strong durable, and high viscosity binding
capacity is required. The porous asphalt mixture is a
mixture of hot asphalt between open-graded
aggregate and modified asphalt with a certain ratio
(Affan, 2006).
Plastic is a commodity that is often used in
everyday life. The most possible way to handle
plastic waste is to reuse plastic (reuse), reduce
plastic consumption (reduce), and recycle (Anonim,
2018). Recycling plastics can be used as a mixture
of asphalt concrete. Asphalt concrete plastic has
been developed in several areas such as Bekasi and
Bali. Asphalt Concrete plastics has several
advantages, namely having a high level of pavement
better, it is not easy to leave a trail of wheels when
wet asphalt is traversed vehicle, and its durability
also increases when compared to ordinary asphalt
(Sumadilaga, 2017). According to (Zulfiani,2012)
that plastic flakes can dissolve in 60/70 penetration
asphalt at a temperature of 1540C. The substitution
of plastic flakes for 60/70 penetration asphalt can
save the use of asphalt by 2.5% of the weight of
asphalt used in the mixture asphalt concrete AC-
WC. With the percentage of PE and HDPE as an
asphalt mixture of 0%, 2%, 4% and 6% of the
weight of the asphalt tends to increase the value of
stability, flow, and VFA but tends to decrease the
values of VIM, VMA, and MQ. The effect of adding
HDPE on the application of asphalt mixture
