TLDR
In this paper, a finite element model was developed to simulate the flexible pavement structure by considering the nonlinear characteristics of subgrade soils which are related to humidity and stress, and a UMAT was programmed to characterize nonlinear moisture and stress-sensitive relationship of sub grade soils.About:

Equations for the soil-water characteristic curve
Delwyn G. Fredlund,Anqing Xing +1 more
TL;DR: In this paper, a nonlinear, least squares computer program is used to determine the best-fit parameters for experimental data presented in the literature, based on the assumption that the shape of the soil-water characteristic curve is dependent upon the pore-size distribution.
