Use of recycled plastic resins in infrastructure construction materials

Recycled plastic resins are routinely used for producing polymer modified highway and building materials and traffic control devices. Disposal of these materials constantly poses a problem for city and state agencies. To address society's need for safe and economical disposal of discarded plastic resins, and the infrastructure community's need for better, long lasting, and cost effective materials, significant research and effort is currently being directed to identifying new uses and applications for these resins. Several of these developments and uses are presented along with the identification of application requirements and needs.
