Use of Waste Plastic Materials in Flexible Pavements

Abstract

Plastic waste generation and disposal  contribute significantly to pollution and global warming.  The properties and strength of bituminous mixtures are both  enhanced by the inclusion of plastic detritus. Also, it will be  a fix for other pavement issues including potholes,  corrugation, ruts, and so forth. It was discovered that  bitumen mixtures used in flexible pavements work well  with plastic as a binder. By preventing cracks and rainwater  infiltration, which would otherwise contribute to the  development of potholes, this efficient method helps  pavements tolerate greater temperatures. For India's hot and  extremely humid climate, where temperatures regularly  exceed 50°C and torrential rains cause havoc and leave the  majority of the roads with large potholes, plastic roads  would be a godsend. Bitumen is used as a binder in the  traditional road construction process. Such bitumen can be  altered with leftover plastic bits to create a bitumen mix that  can be applied as the top coat of flexible pavement. This  modified bitumen made from discarded plastic exhibits  enhanced adhesion, stability, density, and water resistance.
