Due to the high volume of these bottles, more than 1 million m3 landfill spaces are needed for disposal every year. The purpose of this experimental study was to investigate the possibility of using PET waste in asphalt concrete mixes as aggregate replacement (Plastiphalt) to reduce the environmental effects of PET disposal. Concrete is the most widely used man made construction material in the w and its second only to water as the most utilized substance in the planet. Seeking aggregates for concrete and to dispose of the waste from various commodities is the present concern. Today sustainability has got top priority in construction industry. In the present study the recycled plastics were used to prepare the coarse aggregates thereby providing a sustainable option to deal with the plastic waste There are many recycling plants across the world, but as plastics are recycled they lose their strength with the number of recycling. So these plastics will end up as earth fill. In this circumstance instead of recycling it repeatedly, if it is utilized to prepare aggregates for concrete, it will be a boon to the construction industry. Most of the failures in concrete structures occur due to the failure of concrete by crushing of aggregates. Plastic aggregate which have low crushing values will not be crushed as easily as the stone aggregates. These aggregates are also lighter in weight compared to stone aggregates. Since a complete substitution for Conventional Aggregate was not found feasible, a partial substitution with various percentage of plastic aggregate was done. Both volumetric and grade substitution was employed in this investigation. Keywords— Waste Plastic, poly-ethylene terephthalate, Plastiphalt. I. INTRODUCTION The changed lifestyle and endlessly increasing population has resulted in a significant rise in the quantity of post- consumer plastic waste. The world’s annual consumption of plastic materials has increased from around 5 million tons in the 1950’s to nearly 100 million tons in recent times, resulting in a significant increase in the amount of plastic waste generation. Out of this waste, a significant part is recycled but the majority of post-consumer plastic wastes, like shampoo sachets, carry-bags, nitro packs, milk and water pouches etc. though recyclable, remains comparatively untouched as they are difficult to separate from household garbage. In most of the cases, such post- consumer waste either litters all around or is disposed of by land filling. The disposal of post-consumer plastic waste in this manner poses significant environmental hazards as it results in reduction in soil fertility, reduction in water percolation, emission of toxic gases, health hazard to animals and birds consuming the wastes, poor drainage due to landfill, pollution of ground water due to leaching of chemicals from these waste products etc. Disposal of waste plastic consumer bags from the domestic has become a major problem to the agencies in the town and cities. The waste plastic bags available in the domestic waste mainly consist of low density polyethylene (LDPE). Plastic bags dumped in the dustbins find their way into the drainage system and clog them. Often, these are burnt along the roadside, which produces fumes causing air pollution. II. WHY THE PLASTICS  Polymers have a number of vital properties, which exploited alone or together, make  a significant and expanding contribution to constructional needs.  Durable and corrosion resistant.  Good Insulation for cold, heat and sound saving energy and reducing noise pollution.  It is economical and has a longer life.  Maintenance free (such as painting is minimized).  Hygienic and clean.  Easy to processing / installation.  Light weight. III. SOURCE OF EMPLOYMENT IN THE MANAGEMENT OF WASTE PLASTICS Plastic recycling was taking place on a significant scale in an India. As much as 60 % of both industrial and urban plastic waste is recycled which obtained from various
