Abstract:
The issue of moisture damage due to water intrusion in conventional
road pavement is crucial due to increasing traffic load and volume, especially in the
dry process. Poor workability occurs between the aggregate and binder interaction,
increasing air voids in the asphalt mixture. Consequently, reduce the strength of the
asphalt mixture. Hence, the additive material is one possible approach to reduce the
issue. The use of treated plastic (Low-density Polyethylene) (TP) has a high potential
to improve the interaction of aggregate and binder during the mixing process to
against moisture damage. Further investigation on the effect of different ratios of
TP content (0, 2.5, 5.0, 0.75, and 1.0% by weight of total aggregate) in asphalt
mixture was studied. Mechanical performances on moisture damage of the optimum
TP content in asphalt mixture were focused and evaluated with retained stability and
tensile strength ratio tests. The finding revealed that 0.75% of TP content increased
the resistance of moisture damage in asphalt mixtures compared to the conventional
mixture.
