This book gives a clear idea about resent advancement in plastic road construction as well as its various aspects. Also invisigates the possibility of using various plastics in asphalting of roads. The object of work is to describe relevant methods of use of waste plastic in roads along with Eco-friendly disposal of plastic waste, collection of related literature available worldwide for reference & to compare it with actual experimental values. It also aims at importance & use of plastics in daily life as well as proper road connectivity for economic growth, while consideration of its economic aspects & impacts. The experimentation involves preparation of blends of various types of waste plastic with bitumen- a major ingreadent in road construction and coating of waste plastic on aggregates as another process. The modification of bitumen with plastic & road constructed with polymer coated aggregates are tested for various test parameters & compared with normal values. The results are quite positive both ecologically and economically.

This book gives a general overview on the epoxidation process of cottonseed oil. Several methods of epoxidation are available but conventional chemical method is adopted for large scale production. This book also focused on the finding of the potential utility of epoxidized cottonseed oil and developing newer means for its widespread applications. Vegetable oil finds sustainable and renewable source of raw material. The unsaturation present in cottonseed oil can be chemically modified to a value added product by a reaction called 'epoxidation'. Due to the high reactivity of the oxirane ring epoxides can also act as a raw material for synthesis of variety of chemicals such aspolyols, glycols, olefinic compounds, lubricants, plasticizer and stabilizer for polymers and their demand is increasing day by day. Apart from this the kinetics of reaction and thermodynamic properties like enthalpy, entropy, activation energy, and Gibb's free energy were studied at optimized reaction condition. The application of synthesized epoxidized oil was also studied over the epoxy system. Thus an attempt had been made to increase the economic value of the cottonseed oil by converting into epoxidized oil
