Geogrid Game in Geosynthetics: Industry Case Analysis

The geogrid game concept is increasingly used in civil engineering to simulate and optimize geogrid placement in road construction. In the I-95 highway expansion project (USA), engineers faced challenges with soft clay subgrades causing early pavement rutting. By applying the geogrid game approach, different biaxial geogrid configurations were virtually tested, reducing base aggregate thickness by 25%, shortening construction time, and extending pavement life by more than 20 years.

Mining Road Durability

In Australia’s Pilbara iron ore fields, heavy haul trucks caused severe rutting on unpaved haul roads. Engineers used the geogrid game approach to model and optimize triaxial geogrid reinforcement. Maintenance grading decreased by 40%, fuel efficiency improved by 18%, and downtime was reduced, saving operators around $800,000 annually.

Slope Stabilization

On Canada’s Rainy Mountain Highway, saturated soils and freeze-thaw cycles triggered landslides. Using the geogrid game, engineers simulated multiple reinforcement layouts to determine the best solution. Seasonal slope failures were eliminated, vegetation reestablished, and costly concrete retaining walls were avoided.

Railway Ballast Support

European high-speed rail upgrades faced ballast settlement issues. Engineers applied geogrid game simulations beneath the ballast to improve track stiffness and reduce maintenance by 50%, extending track service life and enhancing safety and operational reliability.

The geogrid game approach shows how virtual simulation improves geosynthetics design across roads, mining roads, slopes, and railways. It reduces costs, enhances stability, and enables sustainable, long-term civil engineering solutions.
