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.

Dowel Bar Retrofits: The History of Repairing Faulted Pavements
America’s highway network was created in the 1950s, kicking off decades of long-lasting service by concrete pavements. However, one unforeseen structural issue arose that needed to be addressed: due to a lack of effective load transfer between concrete slabs, faulting occurred. A cost-effective solution in the form of dowel bar retrofit—a pavement preservation technique still in use today—was developed.
