Investigation of Flexible Pavement with Non-Biodegradable Waste Plastic

Waste plastic, which includes the wrappers of junk foods, chocolates, chips, hand-carry bags, plastic bottles, and any other kind of plastic, is mostly to blame for the significant environmental and severe economic problems that are now being experienced in the modern world. When plastics are manufactured, a substantial amount of energy and other natural resources are used. This leads to the depletion of the environment in a number of different ways, which is a consequence of the production process. The longevity of the road as well as its structural integrity are both enhanced by the incorporation of polymer into the asphalt that is used to create the pavement. Polymer, particularly in the form of low-density polymers, is added to asphalt, which results in an improvement in the properties of the asphalt. In the context of transportation, the term "plastic road" refers to roads that are constructed from plastic that has been abandoned. It is well acknowledged that these roads provide improved durability and performance in contrast to conventional roads. Additionally, it has been shown that these highways did not have as many structural problems as their counterparts, which were normal pavements. Certainly, this was a noteworthy discovery. According to the research findings, using a larger quantity of waste plastic ultimately reduces the need for bitumen by ten percent. As a consequence of this, the quality of the pavement as well as the material strength of the pavement are both enhanced. In addition, the incorporation of polymer into asphalt has the potential to enhance the structural strength and durability of flexible pavement. There is a possibility that plastic waste might replace between 10 and 15 per cent of the bitumen that is used in the production of flexible pavement. Furthermore, it has the potential to save around Rs 1,00,724.76 for every additional km of road patch.
