Reuse of Polycarbonate Waste Coated Aggregates - Bitumen Mix Composite for Road Application

Disposal of polycarbonate waste has become a serious problem for human health and waste plastics are burnt for disposal which causes environmental pollution. Polycarbonates are not eco-friendly and as they are non-biodegradable. Generally, it is disposed by way of land filling or incineration of materials which are hazardous. To deal with the problem, study on use of polycarbonate waste as partial replacement to bitumen in flexible pavement is considered in the present work. Road surface with neat bitumen can cause bleeding in hot climate, may develop cracks in cold climate, possess fewer load bearing capacity and can cause serious damages because of higher axle load in present conditions due to rapid infrastructure development and also natural materials quantity is declining gradually. Thus the cost of extracting good quality of natural material is increasing. The present study consists of an experimental approach towards effective waste management, finding alternative to conventional materials in flexible pavements and can promote value addition to the waste plastic. The objective of work is to investigate the effect of polycarbonate waste in flexible pavement and to suggest the optimum percentage of bitumen that can be replaced by polycarbonate waste for the improvement of roads with substantial saving in cost.
