Dowel bar retrofit process turns 30
The concrete pavement restoration/preservation industry last year celebrated the 20th anniversary of the first high production, large scale dowel bar retrofit (DBR) project constructed by the Washington State Department of Transportation. This project utilized specially designed machines that allowed for the placement of hundreds, even thousands of DBR’s in a single day making it a cost effective and viable preservation treatment. What many people don’t know is that the DBR process was actually envisioned and developed nearly 10 years prior to its optimization in Washington. With early research in Georgia dating back to the 1980s, dowel bar retrofit (DBR) has reached its 30th anniversary as an essential pavement preservation tool.
