Abstract:Geocells are robust, lightweight, three-dimension-al fabricated systems that are expandable on-site to form a honeycomb-like structure. Geocells have been intermittently used in roads; they provide lateral reinforcement that increases the bearing capacity of the subbase and subgrade pavement layers. The following are the objectives of this project: i. To evaluate the existing pavement design methods with geocell reinforcement ii. Develop an experimental design to characterize geocells’ improved support mechanisms. iii. Develop a finite element model to replicate the laboratory experiment set up. iv. Conduct experimental and statistical analyses of the collected laboratory data. v. Develop a design system for future pavement construction using geocells. vi. Perform life-cycle cost analysis with pavements using the geocell reinforced layer. vii. Develop specifications and construction steps for future highway construction using geocells.
