As the world population grows, so the quantity of waste being generated. The creation of nondecaying waste material is causing a major problem due to lack of waste management techniques. Therefore recycling
should be considered as a major step in waste management. The amount of waste in circulation can be decreased by
the use of waste materials rather than disposing. Some of the waste materials which can be recycled are glass, scrap
tyres, steel slag, plastic etc. Many of these waste materials have been successfully used in pavement construction. Here
in this project Stone Matrix Asphalt (SMA) mix is being used for the study, for which is modified by adding shredded
plastic waste through dry process and wet process so as to investigate and compare the changes in strength properties
of conventional SMA and modified SMA by conducting Marshall test, to find out flow value, stability, percentage air
voids, voids present in mineral aggregates, voids filled with bitumen, bulk density and to find optimum binder content,
optimum fiber content and drain down characteristics by conducting drain down test.
