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, espacially European work.

The developments focus on the following strategic vectors:

  • The utilisation of resources made of materials in their natural state due to their appropriate intrinsic properties, or which can be improved by treatment techniques for optimal use.
  • Economical and environmental aspects are considered and are to be optimized at the various stages of design and execution of the project.

Part 2 consists of 5 booklets:

2A - Materials

2B - Treatment of materials

2C - Earthworks project
2D - Earthworks execution and controls
2E - Environmental aspects


PART 1 - General considerations
PART 2 - Specific technical development
