Welcome on piarc.org!

PIARC (World Road Association), founded in 1909 and comprising 125 member governments from all over the world, is the global forum for exchange of knowledge and experience on roads, road transport policies and practices. With consultative status to the Economic and Social Council of the United Nations, the Association is contributing to a stable and sustainable global development of the road and transport sector.

Technical Reports Earthworks

This page lists technical reports of PIARC in the field of road earthworks. These publications are classified chronologically.

  • Earthworks Manual - Specific technical developments - 2B - Treatment of materials

    2B - Treatment of materials The Booklet 2B downloadable on this page deals with the treatment of materials. This technique is increasingly carried out to optimize the use of materials under economically advantageous conditions. For Earthworks, the process involves the treatment of natural soils and weak rocks, as well as recycled or artificial materials. The most developed techniques are: short-term soil improvement, applied in particular for excavated materials. medium- and long-term stabilisation, [...]

  • Earthworks Manual - Specific technical developments - 2A - Materials

    2A - Materials The optimal utilisation of materials, locally available on the site, of a road project is today a priority, both from an economic objective and an environmental objective contributing to sustainable development. Consequently, the identification and knowledge of the resources that materials constitute, are fundamental and require in-depth and high-performance studies. The materials used in the construction of earth-structures of a road infrastructure come from various sources. [...]

  • 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

    The use of existing materials in road embankments is an essential issue within the Sustainable Development policies, which have been promoted worldwide for many years. 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).
