Review on Effect on addition of Plastic Waste in Bituminous Mixes prepared with CRMB

Abstract

The need of a improving durability of Bituminous roads is need of the hour to reduce life cycle cost as India has large network of roads to maintain. Modified Bitumen has been found to improve the performance of bituminous mixes. Effect of addition of plastic waste in controlled manner also yields in certain improvement. However a combination has not yet been tried. In this study the addition of plastic has been done by replacing CRMB-55 by percentage by weight in varying percentage (2%, 4%, 6% and 8%). Marshall Stability test was carried out over bituminous mix namely DBM and BC. The aim is to study the effect of addition of plastic by its addition in bituminous mixes prepared with CRMB. It will reduce volume of plastic waste to be disposed of, by incineration or land filling and also improve durability of road which will have positive impact on environment. While on other side, performance of bituminous mixes will also improve with CRMB as ordinary bitumen have early distress symptoms due to heavy loads.
