‘International Road’ Upgraded to Concrete
MORRISVILLE, N.C., Dec. 8, 2011 /PRNewswire-USNewswire/ — When the Town of Morrisville confronted a deteriorated asphalt roadway — one that carries a thousand trucks a day of traffic — and also desired improved, direct access to the once-again thriving Raleigh/Durham International Airport, municipal engineers needed a solution. The cost of the work and the durability of the repair were the primary considerations. The answer? Repave Morrisville’s International Road with concrete.
International Road is a mile-long, non-residential collector road located adjacent to Airport Boulevard and Aviation Parkway and services two concrete plants and two trucking companies doing business there. With constant use — trucks hauling deliveries to and from the plants and trucking concerns — the wear and tear created major failures on the asphalt surface.
Over the course of a year, members of the North Carolina Pavement Association, including Len Swederski, President of Swederski Concrete and Paving; Jerry Reece, Executive Director of the North Carolina Concrete Pavement Association; and Danny Alford, Territory Manager with Argos, USA, demonstrated to Blake Mills, Morrisville’s Public Works Director, through a software application entitled “StreetPave,” the life-cycle cost analysis of choosing concrete pavement to improve the failed roadway.
“Concrete has a much longer useful life of at least 40 years, versus 15 years for asphalt and the cost was only about 20% more than asphalt,” says Mills. “Asphalt really didn’t cut it the first time, therefore a high-strength concrete road seemed like the only viable solution.”
After Mills was convinced that International Road was the ideal “concrete” candidate, the team had to move quickly to get the job done without disruption of business. “In this challenging situation, where hauling requires 24-hour access to the roadway, we could not shut any businesses down,” says Jerry Reece, Executive Director of the North Carolina Concrete Pavement Association. “Our goal was to use a high, early-strength mix in order to achieve concrete strength in three days to get the traffic back on. We beat that goal and had traffic back on the road before Monday.”
In a predominantly asphalt state, the town of Morrisville, NC took a bold step forward, apart from others, by embracing the option to pave with concrete on International Road. While an asphalt thoroughfare, International Road went through repeated cycles of “patchwork” maintenance, but was never adequately restored at any point in time. Redesigned as a durable 8″ – 10″ concrete slab, International Road will now be extended three miles into the Raleigh/Durham Airport.
“Concrete provided a maintenance solution, it was cost competitive and the entire project was completed in 30 days,” says Reece. “It looks beautiful now, and it will be there for at least the next 50 years, if not 100.”
In addition to concrete’s strength, durability and reduced heat island effect from using lighter colored material, the Town of Morrisville was also able to benefit by reclaiming the asphalt that was removed by Swederski and placing the material in an area of the town that needed fill material, completely eliminating any waste.
The Southeast Chapter, American Concrete Pavement Association was incorporated in 1987 and is dedicated to the promotion of concrete pavements for use in interstate highways, state highways, county roadways, municipal streets, local roads, military facilities and airports. The Chapter provides resources that assist members in market development, technical expertise, design, specifications, construction and restoration. For more information, contact www.pavementse.com.
