The obtained results are presented and discussed in this paper showing that the reuse of recycled plastics in asphalt mixtures is a viable alternative that contributes to the reduction of plastic wastes as well as the protection of the environment. An alternate method to use higher percentage of plastic waste in flexible pavement is by using plastic coated aggregate (pca) this method is known widely as dry process the aggregate coated with plastic was used as the raw material.
Recycling of polyethylene terephthalate (pet) plastic bottle wastes in bituminous asphaltic concrete adebayo olatunbosun sojobi 1, stephen emeka nwobodo and oluwasegun james aladegboye mation of the old pavement and perpetual pavements that last 50 years compared to the. Disposal of waste materials including waste plastic bags has become a serious problem and waste plastics are burnt for apparent disposal which cause environmental pollution utilization of waste plastic bags in bituminous mixes has proved that these enhance the properties of mix in addition to solving disposal problems.
A team of city officials, including peter bremner and jeff markovic from kent services, has been working with toronto's greenmantra to develop an innovative new process that coverts 100 percent post-consumer recycled plastic waste into a wax that can be mixed into warm mix asphalt. Plastic wastes in the construction of bituminous pavements dr r vasudevan has stated in his works that the use of plastic in bitumen improves the binding properties of bitumen  prof ceg justo states that addition of 8% percent by weight of processed plastic is desirable in saving 04% bitumen by weight of mix as it improves the. Asphalt” of bitumen) conclusions and recommendations on the suitability and total quantity of bitumen required = 9 tons limitations of plastic waste for blending with bitumen in total quantity of plastic waste required = 1 ton road construction will be drawn from test results cost of bitumen for 9 tons = rs4.

The waste plastic and its disposal is a major threat to the environment, which results in pollution and global warming the utilization of plastic waste in bituminous mixes enhances its properties. Re-use of waste plastic, mainly composed of ldpe and polypropylene in a bituminous concrete mixture, by zoorob and suparma, showed a significant increase in the stability (about 25 times bigger than the stability provided by the control mixes) and durability of the mixture and a decrease in its degree of density.
