The expansion is the capacity of a ground “to be inflated” when its Water content W increases.
This amounts evaluating the variation of the Density apparent according to the water content.
The expansion varies according to the Granulométrie Granulat.
- ρapp, s: Apparent bulk density dries
- ρapp, h: Wet apparent bulk density
- W: Water content
- Mh : wet mass of the ground or aggregate,
- Ms: mass dries of the ground (or considered as dryness, i.e. having passed 24:00 in a drying oven with 105°C).
This formula can also be expressed by
- Mw: Mass water
