Effect of Waste Materials on Bituminous Mix Properties

Abstract

In the present scenario road plays an important role by connecting different cities, rural areas to the main national highways or state highways. However, the construction cost of road is quite high. It is the need of the situation to propose an alternative material as the replacement of conventional ones in order to reduce the total cost without compromising with its actual specifications. India has the second largest road network after China while secured the 12th place in producing of the waste also. Therefore, utilisation of the waste materials in the construction of flexible pavement that will prove as a cost-effective method as well as eco-friendly. Various studies were conducted across the world by focusing on the utilisation of different waste materials like plastic waste (i.e. polythene, plastic bottles, plastic bags, wrappers), waste tire rubber, granite sludge etc. Based on the findings of these studies it was concluded that these waste materials could be used in the flexible pavements. According to previous studies, it was examined that the utilisation of waste material up to 30% has been done without compromising its properties and utilisation of waste material in rural areas for development of connectivity of roads is good option and by using waste materials overall construction cost could reduce and areas can develop in better way.
