Subject(s): Abstract: The goals in this project are to a) quantify the permanent deformations in typical subgrade soils subjected to a realistic soil pattern, b) describe the correlation between shear modulus and strain development for fine granular soils in northern Sweden, c) by FE-analysis model the strain development and recovery time for subgrade materials subjected to heavy truck loads, d) calibrate and verify the FE-model with field measurements of stress, strains and shear modulus at the subgrade.Abstract: The goals in this project are to a) quantify the permanent deformations in typical subgrade soils subjected to a realistic soil pattern, b) describe the correlation between shear modulus and strain development for fine granular soils in northern Sweden, c) by FE-analysis model the strain development and recovery time for subgrade materials subjected to heavy truck loads, d) calibrate and verify the FE-model with field measurements of stress, strains and shear modulus at the subgrade.
