Le compactage vise à densifier le sol en réduisant ses vides. Son efficacité dépend de la teneur en eau, avec une valeur optimale définie par l’essai Proctor, donnant la densité sèche maximale. L’essai CBR évalue ensuite la capacité portante du sol, exprimée en pourcentage de compacité par rapport à un sol de référence.

Compaction increases soil density by reducing voids, with effectiveness governed by moisture content. The Proctor test identifies the optimal water content yielding maximum dry density. The CBR test then measures the soil’s bearing capacity, expressed as a compaction percentage relative to a reference Californian soil for foundation or embankment applications.
