Wheel Rut Repair Presents Affordable Solution to Extend Concrete Life
To address wheel ruts on I-80 in California’s Sierra Nevada Mountains, Caltrans issued emergency contracts to repair the pavement before the 2023/2024 winter season. The ruts were caused by heavy tire chain use and record snowfall the previous season. Because the highway was deemed structurally sound, wheel rut repair techniques presented the best option to repair the roadway quickly while avoiding costly future repairs.
