RISEvaluation on Deformation Behavior of Granular Base Material during Repeated Load Triaxial Testing by Discrete-Element Method
Publisher: ASCE
Abstract: Granular base material (GBM) is widely used as the base/subbase course of pavement structure. In the mechanic–empirical design of flexible pavement, both the resilient modulus and permanent deformation are the major ...
Prediction of Resilient Modulus of Compacted Cohesive Soils in South China
Publisher: American Society of Civil Engineers
Abstract: The resilient modulus has been used to characterize the stress–strain nonlinear behavior of subgrade soils and is the primary property needed for pavement design and analysis. The degrees of stress and moisture content ...
Back-Calculation of Elastic Modulus of High Liquid Limit Clay Subgrades Based on Viscoelastic Theory and Multipopulation Genetic Algorithm
Publisher: ASCE
Abstract: This paper presents a new model for modulus back-calculation for high liquid limit clay subgrades. In this model, the viscoelasticity theory is employed to describe the displacement hysteresis, and the multipopulation ...
