CPR: Rebuilt to Last: Barlow Road & Gateway Avenue rehabilitation, Fort Morgan, CO
Barlow Road & Gateway Avenue in Fort Morgan, Colorado, were rehabilitated using slab stabilization, diamond grinding and joint resealing to prevent water ingress. Slab stabilization addressed pavement distress, and diamond grinding enhanced surface smoothness. These techniques proved effective for long-term use. The nondestructive methods used, including the injection of expanding structural polymer, eliminated the need for pavement removal, saving time and money.

CPR: Rebuilt to Last: California Projects
US-50 in Rancho Cordova, California, enhanced ride quality and noise reduction through the implementation of the Next Generation Concrete Surface (NGCS). NGCS provided a quieter and more comfortable driving experience, supported by diamond grinding and longitudinal grooving. Caltrans closely monitored the suitability, skid resistance, and quietness of the NGCS, leading to its adoption across the state. The success of these projects, often referred to by Caltrans as "Grind and Groove," has resulted in substantial noise reduction and improved surface smoothness, satisfying both taxpayers and residents.

CPR: Rebuilt to Last: Eielson Air Force Base, Fairbanks, AK
A runway section at Eielson Air Force Base in Fairbanks, Alaska, saw rehabilitation through diamond grinding and joint resealing. Diamond grinding restored the runway's condition, and joint resealing prevented water infiltration. These methods extended the runway's service life. The project, which saved significant time and money, was completed almost a month ahead of schedule, ensuring a safer and more efficient surface for the 354th Fighter Wing's operations.

CPR: Rebuilt to Last: First Major Dowel Bar Retrofit Project in Nevada Restores Reno Highway
A highway in Reno, Nevada, underwent a significant rehabilitation project using dowel bar retrofit (DBR) and diamond grinding. DBR restored load transfer, and diamond grinding improved pavement performance. One year following project completion, the improved International Roughness Index (IRI) indicated a significantly smoother ride.

CPR: Rebuilt to Last: I-64 in West Virginia visited by Governor Jim Justice
I-64 in West Virginia experienced significant rehabilitation work as part of West Virginia Governor Jim Justice’s “Roads to Prosperity” Highway Plan using full depth concrete repair (FDR). FDR addressed structural issues and restored the pavement's functionality, demonstrating the effectiveness of this method. Governor Justice's visit to the jobsite underscored the project's success and his commitment to infrastructure improvement.
