Реферат (описание изобретения):
The humidity of the soil and the density of the solid phase of the soil are determined during the yield limit and the density of the aggregate is determined in an air-dried state. The humidity of the soil is additionally measured during a relative water vapour pressure of 0.86-0.92. The differential porosity of the soil can then be calculated, using the preliminarily calculated porosity of the aggregates and the overall porosity for any assigned value of the humidity of the soil.
