Gibraltar Rock Inc., a division of the Silvi Group Companies, is wrapping up the 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 consists of the reconstruction and widening the 14,572-foot-long runway from 150 ft to 200 ft. The reconstruction also will abandon traditional asphalt overlay applications and instead install 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 to the Airport location in Queens, N.Y. The 75-mile haul includes trips through the Lincoln and Holland Tunnels.

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 in 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 Rockís 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.
