In flexible pavements, different kinds of layers are used to withstand the traffic load. CBR value is required to determine the thickness of those layers, especially for base and subgrade materia…

Boussinesq (1842 – 1929) evolved equations that can be used to determine stresses at any point P at a depth z as a result of a surface point load.

Vertical pressure within an earth mass

Boussines…

Boussinesq's theory formula is based on following assumptions.

  1. The soil mass is semi-infinite, homogeneous and isotropic.
  2. The soil has a linear stress-strain relationship,
  3. The soil is weightless…
