Newark, NJ
Conti added 1,800 feet on runway to the current 8,200 foot strip. Because the concrete needed to be as strong and long lasting as possible, the team utilized a “first ever” mix design with four aggregates instead of the conventional three.
In addition to the special concrete mixture used on the runway extension, Conti took advantage of a unique slip-form process to frame the concrete. This process called for the use of a machine to drop the concrete from a conveyor between two steel guides placed 25 feet apart. The machine slowly moved down the length of the runway pouring a depth of 16 inches of material for the first layer. After the first layer was poured, Conti crews placed reinforcing mesh on top, and then applied a second four-inch concrete layer. Another crew then utilized a “rolling bridge” to smooth and finish the surface. This project was also the first time the slip-form paving had been done at Newark Liberty International Airport.
The team executed work at an active airport in a highly urban area with minimal disruption to operations, delivering the project safely and on schedule.
