Technical Reports Earthworks

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

  • Earthworks Manual

    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

    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

    The Earthworks Manual project was launched in 2012 by the Executive Committee of the PIARC Strategic Plan, which entrusted its preparation to Technical Committee 4.4 "Earthworks and unpaved roads". The Earthworks Manual is an important technical document for the profession and stakeholders in the field of activity. It is eagerly awaited by the experts from many countries who have contributed to its content. The Manual is organised in two parts: -   Part 1: General considerations -   Part [...]

  • Preserve Earthworks and Rural Roads from the Impact of Climate Changes

    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

    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).
