Masterclass Description

Geosynthetic-reinforced earth structures and stabilized roads

Geosynthetics have been successfully used for many civil engineering applications by serving different functions. In recent years, engineers have recognized that improving soil mechanical properties by geosynthetics may involve two different functions – reinforcement and mechanical stabilization, which depend on geosynthetic/soil properties and loading conditions. This class will illustrate the differences and relationships between reinforcement and mechanical stabilization by geosynthetics in walls and roads; discuss limit equilibrium and serviceability of geosynthetic-reinforced soil walls constructed under regular and special conditions (e.g., limited space walls, tiered walls, and load-carrying walls) including their design guidelines; and present recent developments in geosynthetic-stabilized roads including mechanisms, design methods, field evaluation, and case studies.
