1.1 Introduction
Waste paints are classified as hazardous wastes, and on an annual basis, approximately 400 million tons of such wastes are generated globally (UNEP, 2012). Besides reducing the cost of bitumen, the use of polymer wastes has a high potential of largely reducing the environmental pollution. The wastes are insoluble in the bitumen matrix to some extent, which would result in gross separation of the two phases (Mashaan et al., 2014 and Hınıslıoğlu et al., 2004). As such, the bitumen phase would be dispersed into a continuous polymer phase. It would then be enriched in asphaltenes by the physical distillation of the lighter species from the original bitumen since maltenes would swell the polymers.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research hypothesis and questions, Limitations of the Study and Definition of technical terms.
