Parametric analysis on usage of Crumb rubber & Waste plastic on to the assessment of improvements leading to production of modified bituminous mix

Plastics are user friendly but not eco-friendly as they are nonbiodegradable. Generally, it isdisposed by way of land filling or incineration of materials which are hazardous. The better binding propertyof plastics in its molten state has helped in finding out a method of safe disposal of waste plastics, by usingthem in road laying.Modified Bitumen is one of the important construction materials for flexible pavements. Use of plastic wasteand Crumb Rubber i.e. the rubber obtained from the waste tyres of vehicles, in the construction offlexible pavement is gaining importance. It is also worth mentioning that, the modifier raw-material has beensourced from disposed waste plastic and crumb rubber. This not only allows us to collect modifier raw-material at low cost, but also provides a solution towards ecological menace posed by increased use ofplastics (non-biodegradable).In the present study, an attempt has been made to use waste plastic andCrumb Rubber. Marshal method ofbituminous mix design was carried out for varying percentages of waste plastic and Crumb Rubber to determine thedifferent mix design characteristics.
