Abstract
Now a days, disposal of plastic waste has became issue of great concern for environmental engineers due its nonbiodegradable characteristics and health hazard. Bitumen is currently one of the most widely used binding materials in road pavement. The reasons due to which bitumen is mostly used as a binding material are its excellent binding characteristics, waterproofing properties and low cost as compared to other binders. However, it is widely known to have various types of distresses and does not perform well in aggressive situations. To counter these shortcomings, bitumen is ordinarily assorted with various forms of modifiers such as polymers, crumb rubber etc. These modifiers are costly and not easily available, so research is focused on waste plastic and polypropylene instead. This study presents results of the waste plastic and polypropylene which have been used as a modifier by an amount of 1%, 3%, 5% & 7% by weight of bitumen in making bituminous mixture for pavement applications. When waste plastic is mixed with bitumen it increases its water resistivity, capacity and stability. Marshal stability test is considered to stimulate with field condition. Flow and stability of the mix increase after incorporating waste plastic. On the basis of experimental work it is concluded that the asphalt mixtures with waste plastic and polypropylene modifier can be used for flexible pavement construction in a warmer region from the standpoint of stability ad flow characteristics
