Guide to Pavement Technology Part 4E: Recycled Materials presents the latest information about products manufactured from recycling various waste materials accepted through registered recycling and reprocessing facilities. This includes the specification, manufacture and application of products derived from the recovery of construction and demolition waste (C&D waste) from the building industry; reclaimed asphalt pavement (RAP) from pavement maintenance and rehabilitation activities; recycled rubber from end-of-life tyres (crumb rubber); industrial slag from manufacturing processes; fly ash from power generation; recycled plastics; and recycled glass.
Recycled materials are continually finding broader application within industry, and it is important that these materials are scrutinised prior to utilisation. An assessment tool has been developed to provide administrative agencies with a framework to rigorously scrutinise emerging materials for potential impacts to economic, environmental, societal and performance outcomes. This framework improves confidence in the uptake of recyclables through mitigation of risk and uncertainty to deliver higher quality assets.
Edition 2.0 is a major edition update with technical and structure amendments made to the entire Guide.
