Concrete pavements are the right choice, whether you’re planning new construction, reconstruction, pavement preservation, or pavement repair and rehabilitation. 

Consider these basic construction strategies, then explore the pavement applications that best fit your strategy.  Looking of more details?  Check out the underlying technologies that make these projects possible, as well as the applications where you will see these strategies used.

 New Construction
Concrete pavements for new construction or reconstruction are typically jointed plain, jointed reinforce, or continuously reinforced.  The concrete slab thicknesses typically range from 6 to 15 in. for roadways and highways, depending on traffic, environment, and soils, as well as the subbase construction.  Concrete pavement slab thicknesses vary significantly—from 6 to 48 in.—depending on the type of facility, class and weight of aircraft, and other conditions.   Technologies | Applications 

Pavement Preservation/Restoration
Agencies/owners today are sharply focused on preserving the pavements that are currently in place. Pavement preservation activities typically include minor rehabilitation, preventive DiamondGround-concrete-CUmaintenance, and routine maintenance to reduce aging and restore serviceability.[1]

Concrete pavement industry offers a wide range of solutions designed to meet these goals, including restorative overlays, joint sealing, diamond grinding, and other processes and products used to apply “the right treatment on the right road at the right time to extend the service life of the pavement.” Examples include diamond grinding; placement of thin concrete overlays; restoration and sealing of joints; and other processes.

Pavement Repair and Rehabilitation
Pavement rehabilitation consists of “structural enhancements that extend the service life of an existing pavement Full depth repair with diamond grindingand/or improve its load carrying capacity. Rehabilitation techniques include restoration treatments and structural overlays.”[2]

In addition to structural overlays, other methods may include joint resealing, slab stabilization, partial-depth repairs, full-depth repairs, load transfer restoration, diamond grinding, stitching, and other processes. Technologies | Applications 

ReDuit-2014construction
When a concrete or asphalt pavement has served its useful life and rehabilitation and preservation options are no longer viable, the options are similar to new construction; however, because of technological advances, reconstructing with concrete pavement may be even more cost competitive than the original, thanks to continual improvements in design, construction, and materials.  Technologies | Applications
