Abstract: Polymers are the backbone of modern day technology and a boon to today's society. However, the disposal of polymer has always been a serious concern of environmentalists. Waste polymer (plastic or rubber) are burnt for apparent disposal, causing environmental pollution. In recent years, considerable research has been conducted all over the world on the use of rubber and polymer in bituminous mixes. Virgin polymers/rubber have successfully been incorporated to enhance the property of bituminous mixes. Limited studies conducted in India have indicated that incorporation of polymeric waste into the bituminous mixes can solve the problem of its disposal. The process is also cost effective and thereby it can turn out to be "waste to wealth" and can prove to a boon to the society at large. This paper elaborates an investigation on the comparative performance of various properties of bituminous concerete (BC) mix containing 8% (By weight of bitumen) plastic/rubber with conventional bituminous concrete mix (prepared with 60, 70 pen. Grade bitumen). Characterization of plastic/rubber waste modifier, bitumen and aggregate is carried out prior to the production of bituminous concrete mix. Properties like Marshall Stability, retained stability, indirect Tensile Strength and rutting were studied. The improvements in engineering properties of modified BC mixes over the conventional mixes are discussed in detail.
