Use of Recycled Materials in Pavements

Back in 2003, PIARC published a report from Technical Committee C7/8 on “Pavement Recycling”. This report contains guidelines for in-place recycling with cement, emulsion or foamed bitumen and hot mix recycling in a plant.

The current literature review is part of a set of three publications on the “Use of Recycled Materials in Pavements” expected for the 2020-2023 cycle.

This literature review describes:

  • recycling in-place using hydraulic and/or bituminous binders, it also addresses the preliminary investigations of the existing pavement prior to recycling it;
  • recycling or re-using in-plant where the recycled materials are mixed in plant, adding hydraulic or bituminous binders, to produce a mix for asphalt or concrete pavements, or for road base layers.

A second publication will be a collection of case studies.

This literature review does not contain any conclusions or recommendations on recycling pavement materials. They will be part of a third publication, which is a briefing note.
