Abstract
"Excess water is known to be the primary cause of soil and foundation problems. In cold regions, water-related problems are exacerbated by seasonal freezing and thawing cycles. Frost heave and thaw weakening is the leading cause of premature pavement failure and consume considerable budgets of the Department of Transportations in cold regions. The first step to designing mitigation measures is the ability to predict frost heave under different conditions. This study aims to introduce a new method for quantifying frost heave using a prediction model based on the state surface approach. This proposed model addressed many inconsistencies and limitations of existing frost heave models and provided a more general and comprehensive prediction model. Each part of the prediction model was then verified using available lab test results or closed-form solutions of known physical processes.
The second goal of this study was to investigate possible frost heave mitigation techniques by reducing excess water in pavement using wicking geotextile. For this purpose, first, wicking geotextile was used in a laboratory test setup to quantify its performance in draining soil moisture. Then, the laboratory results were verified in a full-scale field test section. Finally, a numerical model was developed to investigate the performance of the wicking geotextile under pavement considering full soil-climatic interactions through a novel soil-atmospheric model"-- Abstract, p. iv
