Indonesia is the fourth most populated country in the world. Total vehicles
in Indonesia is 154,376,369 units in 2018-2020, which means there are around 232
units’ vehicles every km. However, many roads in Indonesia can’t provide minimal
conditions for preventing destructions due to failure of the road.
The purpose of this study was to investigate the Marshall Test’s properties
effect (such as: Marshall Stability, Flow, Marshall Quotient, Density, VFWA, and
VITM) of adding crumb of Ultra High Molecular Weight Polyethylene
(UHMWPE) into asphalt mixture, as UHMWPE is a polymeric material that known
as the strongest. In this study, two different UHMWPE’s crumb contents (1% and
2% by weight of aggregate’s total weight) and two different UHMWPE’s crumb
sizes (#50 and #3/4”) were investigated. A comparative study was done among the
unmodified and modified asphalt mixture.
The results showed that UHMWPE is recommended as an additive in
asphalt mixture, as all the results are within the standard requirements. The addition
of UHMWPE tends to increase the strength, higher durability and quality of
mixture.
