Modelling Road Deterioration and Works Effects in HDM-4

This document is the sixth volume in the series of seven volumes of HDM-4 documentation. It gives a detailed description of the road deterioration and works effects (RDWE) models currently in HDM-4 and provides some background to their development, particularly from HDM-III to HDM-4. Also included are possible enhancements to some of the models currently in HDM-4. In addition, other deterioration models are presented in this document for consideration in future versions. The general concepts and [...]

Impacts of road construction and maintenance activities on road users and the adjacent land use

This technical report synthesizes information on techniques to reduce the impact of road construction, rehabilitation and maintenance activities on road users (driving public and construction workers) and the adjacent land use (homeowners, businesses, etc.). The study included a survey to collect agency information and to summarize and draw conclusions on the impact of road construction and maintenance activities on road users (driving public and construction workers) and the surrounding land [...]

Automated Pavement Cracking Assessment Equipment - State of the Art

The type, scope (length) and severity (opening) of cracks in the pavement are essential for road network managers. This information is used to qualify the condition of the pavement and identify the source of surface deterioration. Despite the fact that many highway companies and authorities have invested time and money in designing systems that can automatically report and analyse this type of information, data collection is still primarily done manually throughout the world.

Road Maintenance Handbook - Practical Guidelines for Rural Road Maintenance

This is the second edition --revised, updated and complemented-- of a Road Maintenance Handbook that was first published in 1982 under the auspices of the UN Economic Commission for Africa by Germany, France and the United Kingdom. It is designed for works foremen and is also very useful for engineers and trainers. Special emphasis is laid on intensive labour roadworks and on safety on maintenance job sites in particular. The Handbook is richly illustrated and therefore easy to understand. [...]

Containment Devices on Road Bridges

Drafted by the PIARC Technical Committee on Road Bridges, this report deals with the study of equipment on the outer side of road bridges, i.e. located between the carriageway and the free edge, whose function is to ensure safety of users and frontagers. The report has used the replies to a survey received from the following countries: Australia, Austria, Belgium, Canada, France, India, Israel, Italy, Japan, the Netherlands, Norway, Poland, Spain, Sweden, Switzerland, United States, United Kingdom, [...]
