STUDI PENAMBAHAN KARUNG PLASTIK PADA CAMPURAN ASPAL AC-BC DENGAN METODE PERSENTAGE REFUSAL DENSITY (PRD) --

ABSTRACT
The construction of highway requires good asphalt concrete to support the ability
of the road and to improve the quality of the paved mixture one of them by adding
additives. In addition to additives, it can also modify asphalt with materials such
as rubber, wood powder, and plastic sacks. The method in this study was to
conduct a series of tests on the characteristics of coarse, smooth aggregates, and
fillers then design the composition of the AC-BC mixture and the Marshall test to
obtain the characteristics of the sack mix and the Percentage Density Refusal test
against obtaining Marshall's residual stability value. The levels of plastic sacks
used are 2%, 3%, 4%, 5%, and 6%. The results showed that the use of additives in
concrete asphalt mixtures can increase the value of stability. The stability value
due to the addition of plastic sacks to asphalt mixtures increases compared to
asphalt mixtures without plastic sacks. From the test obtained the optimum
asphalt content value of 5.18% and the optimum level of plastic addition to the
mixture.
