How innovative techniques and strategic planning are delivering long-lasting results

The City of Minneapolis is setting a new standard for sustainable urban infrastructure renewal through its comprehensive Concrete Pavement Preservation (CPP) strategy. Facing the challenges of harsh freeze-thaw cycles and heavy urban traffic, the city's approach provides a valuable model for extending the life of concrete streets.



Since its launch in 2016, the program has demonstrated significant success in rehabilitating its aging concrete street network. By expanding on initial efforts, Minneapolis continues to refine its strategy, delivering cost-effective and durable results.

Highlights of the Minneapolis CPP Program:

·    Advanced Rehabilitation Techniques: The city employs a range of advanced methods to ensure long-term performance, including diamond grinding, dowel bar retrofitting, slab stabilization, and full- and

partial-depth repairs. These techniques address structural issues and improve surface quality. 

·    Sustainability Focus: The CPP strategy prioritizes reusing existing materials, which reduces the need for new aggregates and aligns with environmental stewardship goals. This approach minimizes the carbon footprint of roadway maintenance. 

·    Innovative Contracting: Through the use of Indefinite Delivery/Indefinite Quantity (IDIQ) contracts, the city maintains flexibility in project scope and budget allocation, ensuring efficient use of resources and minimizing public disruption. 

·    Proven Longevity: Pavements rehabilitated under the CPP program are expected to last an additional 25 years, extending their total lifespan to 65-70 years and showcasing a significant return on investment. 

This initiative exemplifies how strategic planning and innovative pavement preservation methods can create more resilient and cost-effective urban infrastructure. Read the full case study on the IGGA website:
