Abstract: From 2002 to 2004, the CER and the LCPC studied the geotechnical characteristics and the
conditions of use of Municipal Solid Waste Slag (MSWS) in embankments (objective of
compaction q4) and in capping layers (objective of compaction q3). This paper shows the
results obtained from one site of incineration.
The water sensitivity of the MSWS is different from clayey material. The Proctor test with
various energies of compaction also shows a strong evolution of the material under the
mechanical action of the compaction. The vibrocompression test with controlled parameters
establishes the strong difficulty of compaction.
In situ, although being sensitive to water, the tested MSWS has significant draining
properties: It changes from a wet state to a medium hydrous state in less than 24 hours. This
hydrous sensitivity leads to reduce the moisture bounds of the medium hydrous class.
The study allows to draw up the conditions of use and compaction tables. It also specifies
the rules of interpretation for the control of compaction by using the dynamic penetrometer.
The continuation of the program consists in checking the similarity of behavior from
another site MSW Slag.
