Experimental study on partial replacement of bitumen by waste materials for pavements

Abstract

Dispatching of debris constituents together with waste shape able bags has become a laborious obstruction and waste plastics are scorched for obvious dumping which triggers eco-friendly contamination. Implementation of waste plastic bags in bituminous amalgams has established that these intensify the stage set of the mixture in accretion to sort out the scraping difficulties. Plastic waste which is dressed and is the chip of a size such that it discharges through 2-3mm sieve by means of shredding machine. The aggregate mixture is warmed and the plastic is effectually layered over the aggregate. This plastic waste overlaid aggregate is blended with hot bitumen and the sequenced mixture is used for road development. Bitumen is in the form of sticky, black in colour and highly viscous liquid. The residue or by-product of the fractional distillation of crude petroleum. Grades of Bitumen used for pavement are Grade: 30/40; Grade: 60/70; Grade: 80/100. Asphalt binder 70/80 was used for the investigation in this paper. The contemporary analysis is only pertinent to the mix design of flexible pavement examinations. Polymers main role to improves the fatigue life, cracking due to thermal, recycled plastics to disposal. This paper also includes the results of the various laboratory tests conducted on bitumen and its properties.
