About the research

The overall goal of this project is to understand the impact of using geocells in granular-surfaced road construction in terms of field performance assessed through measurements of rutting, breakage, stiffness, and strength profiles, as well as resilient properties measured in a large scale laboratory test device with cycling loading. The overall workplan includes construction of field test sections, performance of in-situ tests and sampling through two winter-spring seasons, and laboratory investigations to quantify both the short-term and long-term benefits of geocells to help develop construction guidelines and specifications.
