Evaluation and analysis of highway pavement drainage

this report presents an analysis of pavement drainage using various finite element models. the analysisi included a range of pavement materials and drainage parameters. the computational tool in study was the SEEP/W option in teh GEOSLOPE computer program. a steady-state saturated flow analysis was employed to generate flow paths and flux quantities through the cross-sectional area of the pavement. finite element models in this study covered various drainage practices and quantified their relative drainage advantages. Finally, recommendations were provided for optimum drainage practices as well as future research topics in this area.
