Many of the pavements in the United States’ highway system have reached or are approaching the end of their design life. These roadways still carry daily traffic that often far exceeds their initial design criteria. Concerns about America’s aging infrastructure have been frequently voiced, but the dollars allotted for remedying the nation’s ever-mounting backlog of urgent infrastructure needs has never been adequate for the job. The current COVID crisis has further hindered the need.
Approximately half of all infrastructure dollars are invested in pavements. More than half of that investment is in overlays. By enhancing overlay performance, State and local highway agencies can maximize this investment and help ensure safer, longer-lasting roadways for the traveling public.
A Federal Highway Administration (FHWA) “Every Day Counts (EDC-6)” initiative titled “Targeted Overlay Pavement Solutions (TOPS)” is a series of 6 one-page CP-Tech-Center-developed flyers that tell real-life contractor stories of innovative unbonded & bonded concrete overlays.

These are solutions for integrating innovative overlay procedures into practices that can improve performance, lessen traffic impacts, and reduce the cost of pavement ownership. For the full range of concrete, asphalt, and composite pavement needs, concrete overlays offer:
• Cost-effective
• Versatile
• Short-term solutions
• Long-term solutions
• Preserve pavement service for several decades beyond original design life
• More sustainable construction practices

This TOPS initiative resulted in impressive turnaround times and lower costs, while addressing serious issues in existing asphalt, composite, and concrete pavements. The 6-page single-flyer series covers targeted overlays that fit the treatment to the condition of existing pavements:
• Unbonded Concrete on Asphalt
• Unbonded Concrete on Composite
• Unbonded Concrete on Concrete
• Bonded Concrete on Asphalt
• Bonded Concrete on Composite
• Bonded Concrete on Concrete
