Technical Reports Road pavements

This page lists technical reports of PIARC in the field of Road pavements. These publications are classified chronologically.

  • Use of Recycled Materials in Pavements - Case studies

    This report contains the collection of case studies related to in-place recycling with cement, emulsion or foamed bitumen, hot mix and cement concrete recycling in a plant. The current collection of case studies is part of a set of three publications on the “Use of Recycled Materials in Pavements” expected for the 2020-2023 cycle. This collection reports case studies on: ●   recycling in-place using hydraulic and/or bituminous binders, it also addresses the preliminary investigations of [...]

  • Bridge And Tunnel Strikes By Oversized Vehicles

    This report details the findings of a study carried out by Roughan & O’Donovan Ltd. (ROD) under the supervision of PIARC, in response to an open call for proposals published by PIARC to conduct the “Bridges and tunnels strikes by oversize vehicles” Special Project. The objective of the study was to examine proven countermeasures, practices, and technologies used to reduce the incidence of oversize vehicles striking bridges and tunnels along with effective processes for accurately reporting [...]

  • Overweight Vehicles: Impact On Road Infrastructure And Safety

    This report compiled the available information on overweight road freight vehicles around the world, the impacts they have on road infrastructure, road safety and the economic position of road infrastructure managers, and collected global best practices to prevent and mitigate overloading. Global experience Weight limits for road freight vehicles typically cover 2 aspects: gross vehicle weight and axle (set) load. Gross vehicle weights differ greatly between countries and continents, from as low [...]

  • Reducing the Life Cycle Carbon Footprint of Pavements - High Impact Summary

    In 2019 PIARC published the report “Reducing the life cycle Carbon Footprint of pavements” (2019R33), which was a result from the work conducted by the Technical Committee D.2 – Pavements, during the 2012-2015 cycle. This report assessed and synthesized recent innovations leading to the reduction of Carbon Footprint of pavements. It also presented a critical review of the Carbon Footprint reductions achieved by various innovative technologies when compared to standard methods of construction [...]

  • Use of Recycled Materials in Pavements - Literature review

    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 [...]
