Waste polymers have been studied for various applications such as energy generation and biochemical production; however, their application in asphalt roads still poses some questions. Over the last decade, several studies have reported the utilization of waste plastics in roads using different methodologies and raw materials, but there is still significant inconsistency around this topic. What is the right methodology to recycle waste plastics for road applications? What is the correct type of waste plastics to be used in road applications? What environmental concerns could arise from the use of waste plastics in road applications? Plastic Waste for Sustainable Asphalt Roads covers the various processes and techniques for the utilization of waste plastics in asphalt mixes. The book discusses the various material properties and methodologies, effects of various methodologies, and combination of various polymers. It also provides information on the compatibility between bitumen and plastics, final asphalt performance, and environmental challenges.

Key Features

  • Discusses the processes and techniques for utilization of waste plastics in asphalt mixes.
  • Features a life-cycle assessment of waste plastics in road surfaces and possible Environmental Product Declarations (EPD).
  • Includes examples of on-field usage through various case studies.


Civil engineers, road engineers, structural engineers, material scientists, and environmental engineers.
