CPR: Rebuilt to Last: Concrete Pavement Restoration on State Highway in South Dakota
The city of Watertown, South Dakota, chose diamond grinding and dowel bar retrofit (DBR) for its US 212 project to enhance ride quality and skid resistance. DBR was implemented to restore load transfer across joints. The result was a smooth surface that has remained in good condition for more eight years.

CPR: Rebuilt to Last: Minnesota Department of Transportation utilizes full CPR toolbox and diamond grinding
Concrete Pavement Restoration (CPR) techniques were applied on I-94 between Stearns County State Aid Highway 75 and Trunk Highway 241. The project involved diamond grinding, full depth repair (FDR) and partial depth repair (PDR), joint resealing, crack resealing, and the introduction of Next Generation Concrete Surface (NGCS) to enhance ride quality and reduce noise.

CPR: Rebuilt to Last: US Highway 153, Mosinee, Wisconsin
On U.S. Highway 153 in Mosinee, Wisconsin, partial depth repair (PDR) and full depth repair (FDR) were utilized to restore structural integrity and ride quality. PDR addressed surface defects while FDR tackled deeper issues. These repairs have extended the pavement's lifespan and reduced maintenance costs. The project, completed in 2½ months, highlights the advantages of PDR for quickly addressing shallow problems at joints and extending pavement service life without the need for extensive overlays or replacements.

CPR: Rebuilt to Last: US 52 intersection improvements and resurfacing at Interstate 95, Florence, SC
The U.S. 52 Intersection at Interstate 95 in Florence, South Carolina, underwent full-depth concrete replacement and diamond grinding to address severe rutting issues. Diamond grinding created a smoother surface, and full-depth replacement ensured long-term stability. These efforts successfully restored the pavement's functionality and provided a durable solution expected to last more than 25 years.

CPR: Rebuilt to Last: Concrete patching and maintenance for I-44 in Oklahoma City, OK
On I-44 in Oklahoma City, Oklahoma, extensive Concrete Pavement Restoration (CPR) measures, including diamond grinding, dowel bar retrofit (DBR), full depth repair (FDR) and joint resealing were applied to address transverse joint faulting and improve pavement conditions. Despite challenges such as limited work windows and high traffic volumes, the project was completed successfully in 2005, resulting in significant improvements in pavement service life and ride quality.

CPR: Rebuilt to Last: Interstate 29 southbound between Highway 200A and Highway 200, Hillsboro, ND
Interstate 29 Southbound in Hillsboro, North Dakota, saw significant improvements in the International Roughness Index (IRI) through various concrete pavement restoration (CPR) techniques. Key components included diamond grinding, dowel bar retrofit (DBR), full depth repair (FDR), partial depth repair (PDR), and joint resealing. Conducted primarily to restore load transfer and enhance skid resistance, the CPR methods targeted only the most deteriorated sections, demonstrating cost-effectiveness and flexibility.
