| dc.description.abstract | Road infrastructure is damaged especially in the surface layer or Wearin
Course (WC). Factors that cause damage is the material used in th
mixture. To improve the quality of asphalt can be done by adding additives
This research uses LDPE plastic additives. The purpose of this research i
to determine the value of workability, density, and impermeability
Research using primary and secondary data, KAO determination obtaine
from secondary data, and KPO data obtained from primary data. Then th
research was carried out by making test objects with LDPE plastic conten
of 0%, 2%, 4%, 6%, and 8%, each as many as 3 pieces. From the variatio
of these levels, Marshall Properties testing was carried out to obtain th
Optimum Plastic Content (KPO) value, then tested Workability using
marshall hammer, Density with the volume of the matrix, and the level o
impermeability using a permeability test. The results of the study with th
addition of LDPE plastic in the mixture obtained better results than th
mixture without additives. The effect of additives on the workability valu
obtained results tend to rise at 0% additive content obtained result
103.29% and at 6% content with a value of 111.65%. In testing density a
meet the specifications > 2, the density value of LDPE waste is better tha
the mixture without additives. In the impermeability test with th
permeability method shows the results of the higher levels of plastic wast
are also increasingly impermeable. Optimum plastic content obtained
value of 5.52%. | en_US |
