Promoting optimal use of local materials

This document aims to: • identify the progress made over the last decade with respect to soil and/or rock treatments in the area of road earthworks, and more specifically since the publication of PIARC's 1997 report: "Equipment and Methods Specific to Soil Treatment Work"; • look at developments in the use of local materials in building embankments, subgrade or other structures in certain countries and add to the information already provided in PIARC's reports: "Marginal Materials—State [...]

Slope Risk Guidance for Roads

Slopes are, in general, associated with a greater frequency of failure than other geotechnical assets and a greater threat economically and socially. This report makes a synthesis of risk analysis methods and of vulnerability issues. It presents, in a series of appendices, mitigation measures with their advantages and disadvantages together with a set of case studies.

Road in Desert Areas

Drafted by the PIARC Technical Committee on Roads in Developing Regions, this report provides information on the construction and maintenance of roads in desert areas.

Limits of use of natural soils, specifications and controls in earthworks

During 2000-2003 C12 activity, it was decided to be interested in the limits of use of the soils in the earthworks through the various Member States of the committee and simultaneously to analyse the control methods developed to guarantee the good completion of the work. C12 has considered interesting the mutual knowledge of gathered experiences, although difference of national contexts does not permit easy, direct transposition of the progresses from one country to another. Nevertheless this [...]

International Symposium on Subdrainage in Roadway Pavements and Subgrades

Out of print As is common knowledge in the transportation community, proper functioning of roadways is largely dependent on adequate drainage, both at the surface and in the subsurface. The accumulation of excessive water under pavements typically results in a reduced bearing capacity, leading to distress and premature failure of pavements. Drainage-related problems usually manifest themselves as pavement rutting, cracking, and increased road roughness. The World Road Association (PIARC) [...]
