Design Freezing Index (DFI - deg. F)

Subgrade: Moisture Content - Soil Density:

5% - 100 pcf (1601.8 kg/m^3)

20% -100 pcf (1601.8 kg/m^3)

5% - 115 pcf (1842.1 kg/m^3)

15% -115 pcf (1842.1 kg/m^3)

2% - 135 pcf (2162.5 kg/m^3)

7% - 135 pcf (2162.5 kg/m^3)

2% - 150 pcf (2402.8 kg/m^3)

5% - 150 pcf (2408.8 kg/m^3)

Output:
