Earthworks Manual – General considerations

The Earthworks Manual is a collection of state of the art and good practice to inform readers about earthworks management. Part 1 is a summary of the different phases and associated topics to be considered in the Earthworks process for the construction of earth-structures. The definitions presented are an essential preliminary to provide a common basis for all member countries. The concepts dealt with here, are representative of the whole Earthworks activity, from design of the road infrastructure, [...]

Earthworks Manual - Specific technical developments

The general considerations in Part 1 show in summary the earthworks process and the different phases of construction of earth-structures. The Part 2 develops the specific, transverse technical topics that are most relevant to our field. These topics are dealt with in depth in order to promote the sharing of knowledge of specific earthworks techniques and methods. They are based in particular on feedbacks and technical references resulting from previous PIARC work and also from more recent work, [...]

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: [...]
