Gibraltar Rock, a division of the Silvi Group Companies, is wrapping up delivery of 260,000 tons of stone used to manufacture ready-mix concrete on site in the JFK Airport bay runway reconstruction.
The $376 million project replaces traditional asphalt overlay applications with an 18-inch concrete overlay. The runway reconstruction began in July 2009 and is expected to be completed at the end of 2011.
Gibraltar Rock has been supplying a mixture of numbers 3, 8 and 57 stone at a pace of 75 to 100 truckloads per day from its Belle Mead, N.J., quarry.
Gibraltar Rock was selected because of its ability to handle the volume of daily deliveries, as well as the hardness of the stone required as a Port Authority specification.
Gibraltar Rock purchased the 1,438-acre Belle Mead Quarry from the 3M Corporation in June 2009 and began full production that October. Along with the numbers 3, 8 and 57, Gibraltar Rock also produces dense graded aggregate, screenings, ballast, rail ballast, jetty rock and rip-rap. Gibraltar Rock's stone products are approved by all New York, New Jersey and Pennsylvania transportation authorities.
Reserves at Belle Mead exceed 250 million tons. The plant is rated at 1,000 tons per hour. The facility is also equipped with rail load-out capabilities and recently began shipping railroad ballast to regional rail carrier CSX for their rail line repairs.
