In India, bituminous surfaced flexible pavements comprise of majority of the roads. Distress symptoms, such as cracking, rutting, etc. are being increasingly caused at earlier stages due to high traffic intensity, over loading of vehicles and significant variations in daily and seasonal temperature of the pavement. Investigations have revealed that modifiers can be used to improve rheological properties of bitumen and bituminous mixes to make it more suitable for road construction. Bituminous-mix design involves mixing various size aggregate and bitumen contents in optimum proportions. Electronic waste or e-waste are the discarded electrical or electronic items, which are destined for reuse, resale, recycling or disposal. Informal processing of electronic/ electrical waste in developing countries may cause serious health and pollution problems, as these countries have limited regulatory oversight of e-waste processing. Solid waste management is one of the major environmental concerns in our country now days. The present study covers the use or recycled e-wastes as replacement of coarse aggregates in bitumen. The objective of the study is to investigate the change in mechanical properties of bitumen mix with the addition of e-wastes in bitumen concrete as replacement of aggregate.
