Full-Depth Concrete Pavement Repairs on Arkansas I-57 Ramps
Extending the Service Life of Heavily Traveled Highway Ramps; Transportation agencies seek to maximize the value of existing infrastructure while minimizing impact on motorists. A large-scale concrete pavement rehabilitation project in Arkansas demonstrates how full-depth concrete pavement repair, rapid-setting cement technology, and carefully coordinated nighttime construction can extend the service life of heavily traveled highway ramps while minimizing disruption to motorists. The project addressed 54 ramps along approximately 54 miles of Interstate 57 between the Cabot and Newport areas of Arkansas. The project also included partial depth patching, joint resealing and diamond grinding.

Minneapolis's Concrete Pavement Preservation Strategy
A comprehensive Concrete Pavement Preservation (CPP) strategy can extend the life of aging concrete streets. The City of Minneapolis, facing significant infrastructure challenges from harsh freeze-thaw cycles,
implemented a comprehensive Concrete Pavement Preservation (CPP) strategy to extend the life of its aging concrete streets. By integrating advanced pavement rehabilitation techniques with innovative contracting and a focus on sustainability, Minneapolis has successfully extended the lifespan of its roadways by an estimated 25 years. The program serves as a benchmark for other municipalities, demonstrating a cost-effective, environmentally responsible and long-term solution to urban pavement management.

Largest Asphalt Safety Grooving Project in U.S. History
Longitudinal safety grooving can deliver a safer, more durable roadway for travelers while also achieving
substantial cost savings. The Missouri Department of Transportation (MODOT) recently completed a significant pavement preservation project on Interstate 70 in Montgomery County. By leveraging value engineering, the department successfully enhanced roadway safety while achieving substantial cost savings. This project highlights the effectiveness of longitudinal safety grooving as a viable, resource-efficient alternative to traditional asphalt overlays.
