l Specia : n Sectio NAPA s Award Sheldon G. Hayes Award Paved to Perfection APAC-Missouri, Missouri Department of Transportation receive highest marks to win the 2013 Sheldon G. Hayes Award By Mary Lou Jay P avements that become finalists for the Sheldon G. Hayes Award pass some pretty tough tests over the two-year consideration process. After first winning a Quality in Construction Award, the pavements are evaluated and given a score on a scale of 1-100 based on their ride, uniformity, longitudinal joints, transverse joints, rutting, cracking, surface marks from construction, and the traffic levels they handle. Although all of the 2013 finalists received scores well into the 90s, the work of APAC-Missouri, an Oldcastle Materials Co., of Springfield, Mo., on I-44 earned the highest score. The other three pavements under consideration were constructed by Heartland Asphalt Inc. of Mason City, Iowa; Knife River Materials - Northern Minnesota Division, of Bemidji, Minn.; and The Shelly Co., an Oldcastle Materials Co., of Twinsburg, Ohio. "All four of these were very good pavements, and any one of them would have been a good selection as the winner. It was very close," said Dr. E. Ray Brown, former director of the National Center for Asphalt Technology (NCAT), who did the final on-site judging. "Three of the four projects consisted of an old concrete pavement that had been overlaid with an asphalt mixture," said Brown. "Two of the four projects employed warm-mix asphalt technology using the foaming process. One project contained stone-matrix asphalt (SMA) on the surface, and the remaining projects used dense-graded mixtures. Two projects had very high traffic counts, including high truck traffic, while two of the projects had relatively low traffic levels. "Two things about the APAC-Missouri project stood out, however. First, it had no visible problems such as cracking, and second, it had very high traffic counts," Brown said. "This was an overlay of 1.75 inches, which is unusual; normally there would be a couple of layers. This overlay was also the thinnest of the four, and you would usually think that this would not perform as well for as long, but it is showing very good performance." 22 * View past issues online at APAC-Missouri/Missouri DOT I-44, Jasper County There are some projects where every step goes just as planned. APAC-Missouri's winning project - a half-inch scratch mill-and-fill on a 15.3-mile stretch of I-44 in Jasper County - was one of those, according to Project Manager Tyson Collins. The $4.7 million job included paving on both mainline and ramps, as well as overlay of the shoulders. "It was a nighttime paving project, and that has its own sets of challenges, but for the most part it was pretty cut and dried," said Collins. "We used strategic planning and logistics to achieve proper trucking, plant time, and paving time, so that the roadway could be open by 7 a.m. daily." That careful planning - and the attention that APACMissouri crews paid to every detail of the project - contributed to the outstanding results. 2013 NAPA Chairman John Keating (center) presents the Sheldon G. Hayes Award to (l to r) APAC-Missouri representatives George Blackburn, Foreman; Greg Hayden, Superintendent; Tyson Collins, Project Manager; and David Guillaume, President.
