Focusing on medium- and low-income countries such as Tunisia, Burkina Faso, Morocco, Niger, Côte d'Ivoire and Mali, the report specifically examines the impacts of rural [...]

Preserve Earthworks and Rural Roads from the Impact of Climate Changes - Technical Report

This report puts together good practices on the various regional approaches to the impacts of climate change on roads and little hydraulic works. The subject has already been addressed during previous PIARC cycles but more on the general geotechnical aspect. It includes the definition of the climatic parameters that had to be taken into account, the definition of a rural roads and the terminology of the structure of a road (going from embankments, slopes to the pavement layers). The report covers: [...]

Review of Practices Using Marginal and Secondary Materials in Rural and Industrial Areas - Technical Report

In the World Road Association (PIARC) this subject has been investigated by different Technical Committees over the last 20 years. The optimization of earthwork projects is an obvious issue related to this concern, with important benefits (no spoil disposal or supply of natural noble materials can lead to a strong pollution reduction). [...]
