The use of waste materials in asphalt mixtures has become a popular way of promoting sustainability and reducing environmental impact. Low-Density Polyethylene (LDPE) plastic waste is one such material that has been investigated as a potential additive in asphalt mixtures. Waste plastic in being added in the asphalt mixtures using two process: dry process and wet process. In this research, LDPE waste plastic of size less than 2.36 mm is added in the bituminous mixture using dry process. The objective of the study is to compare volumetric parameters and moisture susceptibility of control and plastic asphalt mixtures. The waste plastic was mixed with the aggregates at 135-145oC for proper coating. The control and plastic asphalt mixtures were prepared as per Marshall mix design and tested for moisture damage as per AASHTO T283. The results indicated that optimum binder content decreased in plastic asphalt mixture with the decrement in the demand of absorbed bitumen due to proper coating of LDPE on the periphery of the aggregate. In terms of moisture susceptibility, plastic mixture found to be less moisture susceptible compared with control mixture.
