Nestled on the island of Oahu, Hawaii, Grace Pacific LLC operates several modern asphalt production facilities throughout the state. Three plants are located on Oahu, one plant on Maui, and one plant each on the Big Island, Molokai, and Kauai for a total of seven plants—all Astec plants.
In late 2012, Grace Pacific purchased a portable 7 ft (2.13 m) Astec Double Barrel® plant. To meet the specs of an upcoming federally funded project to revitalize Saddle Road, a lime silo additive system was added to the plant.
The Saddle Road project bridged the gap between the communities located on the east (Hilo) and west (kailua kona) sides of the Big Island of Hawaii.
"For Saddle Road, lime was needed as an anti-stripping agent to be mixed with the aggregate before entering the drum to be mixed with liquid asphalt," said Darrell Goo, senior vice president with Grace Pacific LLC. "Astec provided a solution to the spec by adding a mixing drum and remote drum bypass unit to the portable plant to mix the lime with the aggregate. The additive system is removable depending on future job needs."
The U.S. Department of the Army built the original one-lane Saddle Road in 1942 to provide access to its military training facilities located in the "saddle" between Mauna Loa and Mauna Kea. During the Saddle Road project, Grace Pacific erected the Astec portable plant at the top of the mountain near Pohakuloa Training Area Base, an army training facility which uses live ammunition, said Goo.
"Saddle Road was in dire need of repair. The road was not feasible for vehicle traffic. The project had been on a wish list for more than two decades. It became reality as an infrastructure project when funded by the U.S. Department of the Army Defense Access Road and Ecosystem Management Programs, U.S. Congress, and the Hawaii Department of Transportation. Saddle Road joined two communities on the Big Island, bringing with it a social and economic boost to the area," said Goo.
The Saddle Road project was completed in October 2013. The portable plant is currently erected and operating in Grace Pacific's Makakilo Quarry on Oahu.
"We plan to keep the Astec plant 'portable.' Some of our other Astec plants started out as portable and then found a permanent home for operations," said Goo. "The plant is easy to transport and could do work on any of the Hawaiian Islands."
Grace Pacific purchased its first Astec portable plant in 1985 and has since bought three more portable plants.
"Owning seven Astec plants reflects the advancements and updated technologies over the years," said Goo. "The support from Astec is undeniable. We are always able to get in touch with Astec's service people, and they provide support on quick and long-term repairs to keep us running. Astec's equipment is built to perform."
Grace Pacific sees a positive year as the mayor of the city and county of Honolulu is targeting the rehabilitation of streets on Oahu.
"Additionally, we will be doing major paving work on H-1 Freeway, and working on two projects at Kahului Airport on Maui using the Astec plant we set up in 1987."
Goo continued: "Our core business is hot-mix asphalt, both production and lay down, and Astec and its subsidiaries have kept us up-to-date on all of the modern technologies and issues facing the industry."BACK TO ISSUE
