Since, being a viscoelastic material, modification is sometimes necessary in bitumen for stability to withstand in adverse environmental conditions. Numerous researches have been carried out on modification of bitumen using nonconventional materials viz. crumb rubber, fibres, etc. In present study, Viscosity Grade (VG) - 30 bitumen is modified with e-waste plastic powder and termed as e-waste plastic powder modified bitumen (EPPMB). Perceptible developments in rheological properties of EPPMB are detected when tested with conventional tests. 5% Ewaste Plastic Powder by weight of bitumen perfectly satisfies the recommendations of Indian specification, hence adopted for further study. Marshall Stability of Dense Bituminous Macadam (DBM) prepared using EPPMB, which
is termed as EPPMDBM, was observed to be enhanced. All Marshall Stability test parameters like ductility, penetration value, flow value and viscosity were experimented and observed to be improved optimistically. Moreover the technical benefits, the study also extends social benefit by providing solution for the non-decomposable electronic waste which is generated in influx now-a-days. Nonetheless, the overwhelming improvements in the technical parameters like resistance to rutting, stripping, cracking, etc are the significant achievements of the study.
