7. Backfill and subgrade compaction
The final section of the GTR guide is devoted to compaction procedures. This subject will be developed in forthcoming dossiers on the execution of works.
The authors would like to thank Mr. Hervé Havard, consulting engineer, formerly Assistant to the LCPC Geotechnics Technical Director.

Module under static loading EV2
The test is defined by standard NF P94-117-1 published in April 2000 (see § Standardization in this "To find out more" section).
It involves two static loadings on a rigid 60 mm diameter plate. The EV2 modulus is determined using Boussinesq's formula:
