Utilization of Waste Plastic in Dense Bituminous Macadam Mixes—An Experimental Study
Bituminous pavements are now expected to perform better as traffic increases steadily and there is a significant change in daily and seasonal temperatures. Scientists attempt to find a way to change the better properties’ of bituminous mixes under variable environmental conditions. This research work describes the effect of low density polyethylene (carry bags) on physical properties of coarse aggregates by dry process. The aim of present study is to understand the concept of utilization of waste plastic (LDPE) in flexible pavement in environmental friendly way along with withstand increased traffic load. Various physical properties of aggregates used in dense bituminous macadam mixes were studied with varying percentage of low density polyethylene (0, 6, 6.5, 7, 7.5, and 8%) of bitumen content. To evaluate the physical properties of aggregates tests such as Los Angles abrasion Test, Impact Value Test, Dorry Abrasion Value Test, Centrifugal Extractor Test, Crushing Strength Test, Stripping Test, Soundness Test, and Water Absorption Test are performed on conventional and waste plastic coated aggregates. Physical properties of aggregate coated with low density polyethylene are improved due to improvement in hardness and toughness, decrease in voids, resistance against weathering action, water resistance, better binding property with bitumen and improvement in abrasion resistance.
