feature Road Warriors What’s new in the asphalt industry? From economy to environment, new products to new specs, it’s the word on the street from the guys who produce it. By Amy Drew Thompson Asphalt has been around in one form or another since the time of the ancients. And although its primary ingredients — oil, sand, stone — remain a formulaic Holy Trinity, it is steadfast evolution that has allowed asphalt to remain one of the construction industry’s most formidable, long-standing products. New mixes that change its gradation, composition, ability to mitigate stormwater runoff and a myriad of other things abound, and in the wake of a recession, and an era in which environmental concerns are increasingly important, industry professionals are paying attention not only to new mix methodology, but the needs of their customers and how best to meet them. says Joe Marrone, asphalt division manager for New Britain’s Tilcon Connecticut Inc. “In the past two years the Connecticut Department of Transportation has let several projects on limited-access highways that incorporate the use of polymer-modified asphalt with warm mix technology.” Other cities and towns have requested warm mix, as well, he says, “to see how it performs.” Named for its lower production temperature, warm mix has only made its way into the American market in the last couple of years, says Brad Oneglia, but he sees it making footholds. Oneglia is the assistant vice president of O&G Industries, Inc., a Torrington-based company founded by his great grandfather in 1923. The reasons for its steady adoption, he says, are multi-fold. “We’re talking about a production temperature that, depending on the data you’re using, is 40 to 70 degrees lower, which would save energy at the plant. You’re not heating this material as much; you’re using less energy to produce it, which is good for the environment and costs.” Additionally, he notes, lower production temperatures are widely held to make for lower emissions – a bonus for those working around the material. Warm mix may even extend the paving season, says Oneglia. In states like Connecticut, where winters halt roadwork in its tracks, that’s worth paying attention to. “There are various ways to make it,” he explains, “various additives that would allow you to achieve compaction at colder temperatures.” The DOT however, says Oneglia (whose company was amid a warm mix project at press time), is not putting all its eggs in the warm mix basket just yet. A number of projects he’s seen specify the use of hot Warm mix “There is a tremendous focus on producing greener and longer lasting materials,” 14 / CONNstruction / Winter 2012
