Green Paving Solutions and Sustainable Pavement Materials - Technical Report

This report summarizes the current state-of-the practice for sustainable pavement techniques and the incentives used to encourage their use. Green paving solutions were identified in addition to identification of barriers to their wider implementation. Information contained in this report is based on a literature review and a questionnaire and survey of 42 representatives from 20 countries across the world. Sustainable pavement techniques can be incorporated into pavements from the pavement design [...]

State of the Art in Monitoring Road Condition and Road / Vehicle Interaction - Technical Report

This report is a follow-up on the report "State of the art in monitoring road condition" which was finalised in 2015 (PIARC reference 2016R17EN). The 2015 report summarises the then current state of the art regarding the collection of road condition and road/vehicle interaction data, providing an overview of current practice and emerging technologies. The current report is an update of some chapters due to new findings as a result of recent research. It also discusses technologies in the development [...]

Review of the Practical Guide to Pavement Design for Tropical Countries (in French only) - Technical Report

The Practical Guide to Pavement Design for Tropical Countries, published in 1984 by CEBTP, is still a document to which reference is often made in French-speaking African countries. Over the past thirty-five years, major developments have taken place in the pavement sector, particularly in the formulation of pavement materials and the design of pavement layers, while African countries are experiencing strong growth in heavy goods vehicle traffic, requiring the widespread use of pavements on the [...]

Expected service life of wearing courses

As part of its 2012 to 2015 strategic plan the World Road Association (PIARC) determined the need to identify and review approaches taken in assessing the service life of wearing courses. This report reviews the different approaches taken by road authorities to determine the service life of wearing courses. The aim is to understand why they are replaced and identify the factors that affect decision-making. The service life of a wearing course depends on several factors such as the type of wearing [...]
