| Summary: | Pakistan is a land filled with natural resources, but gradually due to depletion of these, the country aims to benefit use from different materials that can serve the intended purpose with the minimal cost. Our country annually generates 3.3 million tons of plastic waste. The plastic waste disposal is one of the most threatening challenges to all major metropolitan areas around the world. If not sorted out immediately, it might degrade in the environment for many years. This study proposes the use of waste PET bottles in road construction. The main objective is to analyse and compare the properties of plastic-mixed bitumen roads over non-plastic mixed bitumen roads. Shredded plastic bottles were mixed with bitumen in different ratios (0%, 6%, 8% and 10%) to enhance the stability and durability of roads. Different tests like Marshall stability, penetration, ductility, and softening tests were performed in the laboratory. The results showed that bitumen with 8% plastic has a low flow value. Also, the plastic modifier to bitumen increases the density of the mixture which improves the structural performance of the asphalt pavement. There is an increase in the softening point which illustrates that plastic modified bitumen roads can withstand hot weather more effectively than traditional bitumen roads This addition of plastic in bitumen will be a boon for Pakistan's road industry. |
