Abstract: This paper presents a case history of the backfill design aspects for the Algeria Rail Line 175 embankments using French design specifications. The French design specifications requirements in the rail embankment construction are also introduced. The French code in the geotechnical material classifications, backfill types, location of the backfills, requirements on the compaction of the backfill materials are discussed. The French code and Chinese code are compared. The different and common points in both design specifications are presented.
