Preparation of Plastic Road using Single Used Waste Plastic
Summary
Researchers found that mixing shredded waste plastic (like grocery bags and food containers) into road pavement material makes roads stronger and longer-lasting, while also giving single-use plastics a useful second life instead of piling up in landfills or waterways. This matters because it tackles two problems at once: less plastic waste breaking down into microplastics that pollute soil, water, and eventually our food and bodies, plus more durable roads that need fewer repairs. That said, this study focuses on road performance and cost—more research would be needed to confirm there's no risk of plastic particles leaching out of pavement over time.
Plastics are the non-biodegradable materials and means to degrade our environment. The waste plastic and its disposal is a major threat to the environment, which results in pollution and global warming. The utilization of plastic waste in bituminous mixes enhances its properties and also its strength. In addition, it will also be a solution to plastic disposal & various defects in pavement i.e., pot holes, corrugation, ruts, etc. the waste plastic used are poly-ethylene, poly-styrene, poly-propylene. There are two processes available for the mixing of plastic in bituminous mix such as wet process and dry process. The waste plastic is shredded & coated over aggregate & mixed with hot bitumen and resulted mix is used for pavement construction is known as the dry process. But in wet process waste plastic is ground and made into shredded form; various percentage of plastic is mixed with the bitumen and study the durability of the roads laid out with shredded plastic waste is much more compared with roads with asphalt with the ordinary mix which is the objective of the present study. The use of the innovative technology not only strengthened the road construction but also increased the road life as well as will help to improve the environment and also creating a source of income. It's economical and eco-friendly. In this project, we have discussed about the bitumen with plastic properties to be considered in design of pavement, pavement design, and process of construction flexible pavement.
