THE RESILIENT AND PLASTIC CHARACTERISTICS OF MICHIGAN SUBGRADE SOILS AND THEIR SOIL SUPPORT VALUES
In this study, the plastic and elastic characteristics of Michigan cohesive subgrade soils are evaluated using repeated load triaxial tests on undisturbed samples. The results of the investigation led to the development of a normalized predictive model of the plastic strain. The model has demonstrated its ability to evaluate and predict the plastic behavior of several materials subjected to cyclic loadings. The input parameters of the model consist of the static strength and the corresponding total strain of the material in question. The model was tested and evaluated using five different materials ranging from gravel, sand, clay and clayey silt. The developed normalized predictive model neutralizes the effects of several sample and test variables. The model was found to be unqiue for each class of soil and independent of compaction, density, water content and stresslevel. Further, the model was used to develop a new approach and understanding of the soil support value of the AASHTO Interim Guide for the design of flexible pavement. (FHWA)
