Earthworks Manual - Specific technical developments – 2D - Earthworks execution and controls

The Booklet 2D downloadable on this page, deals with the execution of the earthworks, based on earthworks studies and project, covered in Booklet 2C.

Like Part 2C, Part 2D of the Manual concerns major linear infrastructures, road or rail, for which the economic and environmental issues are particularly highlighted.

The Booklet 2D deals with the following components:

Optimization of the earthwork project at the construction stage

The earthworks project studies, earth movement and associated planning, as well as the adequacy of equipment resources, are finalized at the construction stage.

Adaptations of the project to the encountered ground are generally necessary, in particular according to complementary geotechnical investigations.

Construction processes for earth-structures

The processes result from site material resources and construction provisions of earth-structures, defined by the project.

The constructive provisions considered are relating to the earth-structures including structural layers of the infrastructure and to specific particular structures.

Specific construction provisions concern including particular structures, slopes - cuttings and fills - and base fill area.

Earthworks operations

The various earthworks operations, excavation and loading, transport, grading, final adjustment, compaction, are optimized by the choice of equipment and techniques, according to the nature of materials.

Productions and construction costs

This booklet presents the main elements for assessing the costs of earthworks for infrastructure projects. 

Earthworks monitoring and control 

Controls concern the execution of works and the conformity of built structures. The booklet deals with the different types of specifications and controls, their organization and the main testing methods used in the earthworks field.
