Fort Drum Connector Bridge Beams - Jefferson County, NY

The concrete specified for the 100' x 84" high beams fell under the New York State Department of Transportation (NYSDOT) high-performance concrete specifications, which requires the use of 5 gal/yd3 (25 L/m3) of a calcium nitrite-based corrosion-inhibiting admixture. The concrete had to achieve a compressive strength of 8,500 psi (58.6 MPa) in 34 hours and 10,100 psi (69.6 MPa) at 28 days in order for New Enterprise to meet scheduling requirements.

I-93 Rapid Bridge Replacements - Medford, MA

14 bridges on Interstate 93, where the traffic volume is 200,000 cars per day, needed replacement due to deterioration of the concrete. Using normal construction procedures, this project would have taken at least five years to complete. In order to accelerate the project and minimize the impact on commuters, accelerated project development and construction techniques were used.

I-5 "Boat Section" Replacement - Sacramento River, CA

California’s Interstate 5 is the main north-south  highway on the West Coast. The three-quarter mile stretch of I-5 along the Sacramento River is often referred to as the “Boat Section” since it lies below water level and required draining of the area when it was originally built in the 1960s. Since then, the Boat Section has been plagued by river silt and sand blockages in its drainage system, which allowed water to be pushed up through the pavement and cause cracking and deterioration. Replacement of the Boat Section was critical to better accommodate the nearly 200,000 trucks and motorists that drive the stretch daily.

Alamo Truck Stop Weigh Scale - Sparks, NV

The Alamo truck stop weigh scale in Sparks, Nevada is a major source of revenue for the city. An estimated 43,800 big-rig tractor-trailers, weighing approximately 150,000 to 160,000 lb (68,180 – 72,730 kg) each, use the annually to accurately determine their load. The asphalt around the approach and exit areas of the scale ruts severely due to the constant low-speed start-and-stop truck traffic entering and exiting the scale and historically has been repaired on an annual basis.
