Geocell is a type of three-dimensional honeycomb geosynthetics that is widely used to improve theperformance of paved and unpaved roads by reinforcing the base/subbase courses. It has numerous advantagessuch as improvement of long-term performance of roadways, reduction of construction cost, and reduction ofcarbon footprint. Although geocell has been widely used in roadway construction in cold climatic regions,research regarding the behavior of geocell-reinforced bases subjected to freeze-thaw cycles is rather scarce. Agood understanding of the effect of freeze-thaw cycles on the performance of geocell-reinforced bases is vitalto the design and construction of roadways. This project will help Stratum Logics get insight into themechanisms of geocell reinforcement in roadways under freeze-thaw effects and improve the design method toensure the serviceability of roadways in Canada.
