2. Long-Life Pavement
FHWA Conference on Long-Life Concrete Pavements – October 2006.
What is a Long-Life Pavement?
Original service 40+ years;
No premature construction defects or material-related distress;
Reduced potential for cracking, faulting & spalling;
Smoothness and surface texture easily maintained.

3. Benefits Derived from Long-Life Pavements
Maintenance of Traffic
Work Zone Safety
Reduced User Delays
Life-Cycle Cost
Sustainability
Economic Impacts
Environmental Impacts
Social Impacts

4. Long-Life Pavement Options with Concrete – Jointed Plain (Reinforced);
Continuously Reinforced;
Precast Jointed;
Precast Prestressed;
Bonded Overlays;
Unbonded Overlays;
Roller Compacted.
