A Synthesis on the Effects of Two Commercial Recycled Plastics on the Properties of Bitumen and Asphalt
The desire to develop sustainable infrastructure, including pavement structures and materials, is ever increasing in recent times. One opportunity is to partially replace high-cost bituminous binder with low-cost recycled plastic in asphalt mixtures. This synthesis combines the various research effo...
