CPR: Rebuilt to Last: Pavement rehabilitation in Jamestown, MD

U.S. Highway 281 in Jamestown, North Dakota, underwent concrete pavement rehabilitation methods to extend pavement life and minimize disruptions. Full and partial depth repair, joint resealing and diamond grinding were implemented to restore structural integrity and performance. These measures ensured cost savings, extended pavement life by 15 to 20 years, and minimized disruptions to local traffic and businesses. The project, completed two months ahead of schedule, demonstrated the benefits of targeted pavement preservation techniques.

CPR: Rebuilt to Last: Bullitt County, KY road repair

Bullitt County roads in Kentucky saw enhanced ride quality and extended pavement lifespan through comprehensive rehabilitation efforts. The project involved employing techniques such as diamond grinding, full depth repair (FDR) and joint resealing. The project enhanced ride quality, safety, and extended the pavement's lifespan by eight to nine years, demonstrating cost-effectiveness and efficiency.

CPR: Rebuilt to Last: Interstate 270 and State Route 62, Grove City, OH, Franklin County

Interstate 270 and State Route 62 in Grove City, Ohio, addressed noise complaints and improved ride quality through diamond grinding. The project involved grinding the concrete surface to remove transverse tining and achieve a smoother profile, along with replacing raised pavement markers and sealing deck surfaces on bridge sections. This technique significantly reduced road noise and enhanced the overall driving experience.

CPR: Rebuilt to Last: Concrete patching and resealing maintenance for major city roads in Glen Ellyn, IL

City blocks in Glen Ellyn, Illinois, were rehabilitated using diamond grinding and full depth repair (FDR). Diamond grinding enhanced surface smoothness, and FDR addressed deeper structural issues, leading to improved urban road quality. These methods provided a cost-effective, long-term solution for preserving the roads, with an expected lifespan extension of up to 10 years.

CPR: Rebuilt to Last: Rapid road repair in Highlands Ranch, CO

Highlands Ranch, Colorado, utilized an innovative repair approach combining slab-jacking and diamond grinding to address severe faulting. Slab-jacking corrected pavement faults, while diamond grinding improved ride smoothness. This combination of techniques proved successful. The project, completed in seven days, demonstrated the efficiency and cost-effectiveness of this method, extending the road's lifespan by 10 to 20 years and minimizing traffic disruptions.

CPR: Rebuilt to Last: I-195 from I-95 to Valley Street, East Providence, RI

I-195 in East Providence, Rhode Island, reduced noise and enhanced ride quality through diamond grinding. The work also incorporated joint resealing and crack resealing to ensure long-term durability. This project was notable for its use of a noise reduction specification, a first in the U.S., requiring the diamond ground surface to meet a noise target of 102 dBA or less. Completed in December 2012, the project resulted in a 60-70% noise reduction and a smoother ride, expected to last 20 years.
