A stress-deformation based algorithm for quasi-static designing unreinforced unpaved roads incorporating operational stabilities
Source abstract
Abstract
This paper presents a coupled stress-deformation-based algorithm in a finite element framework for quasi-static designing of unreinforced unpaved roads comprising generalised subgrade, considering both frictional (φ) and cohesive (c) components of subgrade shear strength. Further, this algorithm considers the deformability-based operational failure of individual components of unpaved road section. In the algorithm, the limiting strength parameters of aggregate and subgrade are to be identified that would ensure the operational stability of the natural subgrade under aggregate loading as well as the stability of the aggregate layer under quasi-static vehicular loading. Even after the operational stabilities are ensured, weaker subgrades when subjected to heavier axle loads have the tendency to exhibit failure due to the transmission of the secondary stresses, which is also considered in the design algorithm. The coupled stress-deformation-based design algorithm reported herein provides a comprehensive design approach duly incorporating all such operational failure conditions.
