Question

A permeability test is carried out on a sample of and cross section is 1500mm^ 2 a soil whose k = 3 * 10^(-1) m / s. 

  1. Briefly identify this while indicating its degree of permeability
  2.  What diameter of measuring pipe do we use knowing that the load goes from 275 mm to 200 mm in 5 min?
  3. Compare the permeability of this soil identified in question a) with that of a sandy silt. Justify your answer
  4. Compare the frost hardness of the soil identified in question a) with that of gradual sand. Between these two soils, which will be the most suitable as road fill without risk of frost swelling? Justify your answer
