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.

土工格室是一种三维蜂窝状土工合成材料，广泛用于通过增强基层/底基层来改善铺筑和未铺筑道路的性能。它具有许多优点，如改善道路的长期性能，降低建筑成本，减少碳足迹。虽然土工格室已被广泛应用于寒冷地区的道路建设中，但关于土工格室加固基层在冻融循环下的性能研究却相当缺乏。深入了解冻融循环对土工格室基层性能的影响，对公路的设计和施工具有重要意义。该项目将帮助Stratum Logics深入了解冻融影响下道路土工格室加固的机理，并改进设计方法，以确保加拿大道路的可用性。
