Technical Reports Road pavements

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

  • 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 (2019R33) - 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 [...]

  • Methodological Document for the Establishment of a National Catalogue and Pavement Design Guide - Technical Report

    Following the critical review carried out by a joint PIARC/AGEPAR working group, of the 1984 edition of the Practical Guide to Pavement Design for Tropical Countries, produced by CEBTP, PIARC and AGEPAR approved the extension of this work by producing a methodological document for road administrations in French-speaking sub-Saharan African countries that are considering the development of a catalogue of new pavement structures. The Catalogue and design guide are two complementary documents: the [...]

  • Reducing the Life Cycle Carbon Footprint of Pavements - Technical Report

    This report reviews innovations reported to reduce the carbon footprint of pavements and contains a critical review of the assessment of carbon footprint of pavements. There are numerous other environmental indicators for road pavements, but these were outside the scope of this report which focuses only on the carbon footprint. The strategic objectives established for the working group were as follows: review field feedback on recent innovations (products, equipment) which contribute [...]
