Rigid factor in the design of highway pavement is a measure of the stiffness of the pavement layers which is determined by analyzing the road structure to determine its ability to carry loads without experiencing permanent deformations.
It is usually expressed as a ratio of the modulus of elasticity (E) of the pavement layer to the subgrade (kappa). The higher the rigid factor, the stronger the pavement layer and the more resistance it offers to permanent deformations caused by traffic loads.
