Lindy Wins Top National Award for Quality in Asphalt Paving 2005
Lindy Paving Inc. Wins Top National Award for Quality in Asphalt Paving
Lanham, MD: The National Asphalt Pavement Association (NAPA) announced today that Lindy Paving Inc. of New Castle, PA, has won the 2005 Sheldon G. Hayes Award for excellence in construction of an asphalt pavement. The company received the award on January 24 at the Association’s 51st Annual Convention, “Ride the Pavement,” in Hollywood, FLA.
The company’s winning project was the milling and overlay of 6.1 miles of Parkway West (I-279 North) in Pittsburgh, PA. Lindy Paving and the Pennsylvania Department of Transportation partnered on the $7.8 million job from the start, revising the original design and hot-mix asphalt (HMA) mixes to provide motorists in the state with the smoothest possible pavement.
The most difficult part of the job was the time schedule, according to Lindy Paving’s President Vince Tutino, “We had to do all this work in just eight weekends. On jobs like this we’d usually have from April to November to complete it.” Lindy Paving would close sections of the road at 10:00 on Friday nights, mill it down to the concrete, and then lay 10,000-12,000 tons of asphalt before reopening the road-with the wearing course laid and the stripes painted on it-by 6:00 Monday morning.
Wet weather made the timetable even tighter. “If there was a rainout day or weekend we had to make it up. We would bring in more milling machines so we could double the areas that we were working. We even brought a jet engine-the kind they use to dry racetracks-out to the job site to dry the surface so we could work,” said Tutino
To complete the job on time, Lindy Paving Co. had as many as three paving crews working 12-hour shifts round the clock. “Sometimes we’d have as many as five operations going on at one time,” Tutino continued. There were often more than 100 trucks working on the site or delivering materials to it. Despite all this activity, there were no accidents during this job.
The asphalt for this project came from Lindy Paving’s three plants in the area, which produced a combined total of 72,741 toms of HMA for the road.
Despite the difficult weather, the logistical problems, and the amount of high-quality HMA required, Lindy Paving and its subcontractors finished the job by the deadline. The completed road surface showed a 60 percent improvement in IRI (international roughness index) over the previous surface.
“When we’d open the road on a Monday morning, we’d hear people commenting on the radio about how they couldn’t believe how much we’d done, and how smooth the road was,” says Tutino. “This really was a once-in-a-lifetime job.”
The Sheldon G. Hayes Award winner is determined through a two-year process Highway pavement projects using more than 50,000 tons HMA are eligible for consideration. Initially they must win a Quality in Construction (QIC) Award, which is determined by numerical scores given by pavement engineers at the National Center for Asphalt Technology (NCAT) on the basis of how well the contractor met specifications and achieved density on the finished pavement. All the pavements that meet a benchmark figure are given the QIC award.
The year after a project wins a QIC Award, it may be considered for the Sheldon G. Hayes Award. The top-ranked project from each year are tested for smoothness, then visually inspected by an independent pavement consultant with many years of experience in the industry. This year, the evaluators praised the contestants for high-quality construction practices resulting in smooth, safe, and durable pavements.
The National Asphalt Pavement Association is the only association that exclusively represents the interests of the hot-mix asphalt producer/contractor on the national level with Congress, government agencies and other national trade and business organizations. NAPA supports an active research program designed to improve the quality of HMA pavements and paving techniques used in the construction of roads, streets, highways, parking lots, airports and environmental and recreational facilities. The association provides technical, educational, and marketing materials and information to its members and supplies technical information to users and specifies of paving materials. The association, which counts more than 1,100 companies as its Members, was grounded in 1955.
