This report documents and presents the use of steel fiber-reinforced rubberized concrete (SFRRC) in cold regions. Further investigation of SFRRC use was conducted with the wheel tracker rut and freeze-thaw laboratory testing procedures at the University of Alaska Anchorage. Wheel tracker results showed significant rutting improvement in SFRRC compared with asphalt, and freeze-thaw testing showed low significant resistance to cracking and compressive strength loss in SFRRC compared with standard Portland cement concrete. An experimental cast-in-place panel was installed at the University of Alaska Anchorage and subjected to traffic with little signs of wear. Following this, pre-cast panels were designed and placed in a high-traffic urban arterial to determine rutting, freeze-thaw resistance, construction methods, and life cycle cost. Design, construction, and installation of the panels were completed on the Abbott Road construction project in the summer of 2017. The panels will be monitored and analyzed to determine the viability of SFRRC in roadway systems.
