Experimental Investigation and Field Monitoring of Geocell- Reinforced Roads under Freeze-Thaw Cycles

Freeze-thaw is a major cause for distress of roads in Canada. This research project is to investigate the use of Neoloy geocells to strengthen the roads to minimize the freeze-thaw damage. A fully instrumented road stretch will be constructed to monitor the long-term performance of the geocell-reinforced roads subjected to seasonal freeze-thaw cycles. Meanwhile, a series of laboratory-scale model tests will be conducted. The outcomes of this project are (1) quantifying the beneficial effect of geocells in reinforcing roads against freeze-thaw damage, (2) understanding the underlying reinforcing mechanisms, and (3) development of relevant design method. The results of this research will contribute to improvement of the design and construction practices of durable roadways in Canada.
