Surface Dressing - Practical Guide for Technology Transfer

This guide was drafted by the Technical Committee on Roads in Developing Regions in agreement with the PIARC Technical Committee on Flexible Roads. Surface Dressings Throughout the World : documents analysed in 12 countries (Australia, Belgium, Brazil, Colombia, France, Ivory Coast, Morocco, Niger, Portugal, Republic of Korea, Spain, United Kingdom) Comparative Analysis of Different Surface Dressing Designs : aggregates -binders - design - rate of spread Assessment : aggregates - binders [...]

Achieving and Maintaining the Evenness of Concrete Pavements

Whereas concrete pavements have well-known advantages (long life, resistance to permanent deformations, etc.) over flexible pavements, the main disadvantages often mentioned are a certain lack of comfort as a result of neglected surface evenness, and a high level of rolling noise. Developments in construction techniques, in particular their gradual adaptation to slip-form paving machines, permanently raise the problem of achieving the best possible evenness. That is why the PIARC Technical Committee [...]

Semi-Rigid Pavements

The first chapter deals with terminology. Chapter II explains why one may be led to choose a semi-rigid pavement from all the various types available, and chapter III describes the various possible designs of these pavements. Chapter IV then discusses the methods used in designing semi-rigid pavements, giving examples of the pavement structures used in various countries. This is followed by a description of the constituents of the materials treated with hydraulic binders, the methods used in choosing [...]

Innovative Pavement Design

The sub-group 2 of the PIARC Technical Committee on Road Pavements (C7/8) includes 24 representatives belonging to 18 countries. The task assigned to this group was to identify, analyse and recommend innovative pavement typologies corresponding to needs really expressed by the different countries and the different national, regional and local road network contexts. The aim was to describe the most appropriate choices for favouring the spirit of creativity inherent in innovation as well as the best [...]

A Fact Finding Review of Performance Specifications in 2002

This document is an awareness-raising review of the current state of the art for performance specifications. It provides insight into three important areas of performance specification and presents the responses to an international questionnaire on the subject. The three important areas of discussion are appropriate definition; initial and whole life cost implications, and the use of warranty periods in the procurement contract.
