Pengaruh Pemanfaatan PET pada Laston Lapis Pengikat Terhadap Parameter Marshall

Abstract

Utilization of plastic waste can be used as an ingredient added to the binder layer of asphalt
concrete (AC-BC). The purpose of this study was to determine the characteristics of the Marshall
parameters due to the addition of PET (Polyethylene Terephthalate) in the binder layer of asphalt
concrete (AC-BC) using the method of Marshall and refer to the specifications of Highways, 2010.
The research was carried out by adding pieces of PET in the asphalt mix using the dry method.
Before adding PET to the asphalt mixture, first making a specimen of middle limit gradation and
upper limit gradation. The value of Optimum Asphalt Content (KAO) obtained in the two groups
of test object is equal to 6.44%. Furthermore, the addition of PET in the asphalt mix on the KAO
value. PET levels are added to the mixture which is 2%, 4%, 6%, 8%, and 10% of the weight of
the asphalt. From the results of the testing and analysis of Marshall, the addition of PET on
asphalt concrete binder layer can increase the value of stability. The most of stability value is on
the addition of 2% PET. Value stability due to the addition of PET in the asphalt mix increased
compared to asphalt mixture without PET. Levels of PET good addition to the asphalt mixture that
is 2% because in addition to high stability values, parameters such as VIM Marshall, VFA, VMA,
MQ and Flow also has qualified specification of Highways, 2010.
