FAQ

What is Structural Number for the Subbase Course?
Structural Number for the Subbase Course is defined as an abstract value that expresses the structural strength of the overall pavement and is represented as SN3=(an*Dn*Mn) or Structural number for the subbase course=(Layer coefficient*Actual thickness*Drainage coefficient). Layer coefficient can be represents the strength of the material, this is the primary variable that factors in the type of material you plan to use for each layer, Actual thickness can be described as the design thickness of various layers of the cources for the flexible payments and Drainage coefficient is a value assigned to a pavement layer that represents its relative loss of strength due to drainage characteristics and exposure to moisture saturation.
How to calculate Structural Number for the Subbase Course?
