Preservation 'roadmap' Better Roads Magazine Share ![]() ![]() ![]()
A new "roadmap" indicating the direction of research in pavement management and preservation is coming at just the right time, as states begin to openly curtail capacity improvements in favor of pavement preservation. More Stretching exercises: Using digital images to understand bridge failures Public Works Share ![]() ![]() ![]()
With a random-looking spatter of paint specks, a pair of cameras and a whole lot of computer processing, engineer Mark Iadicola of the National Institute of Standards and Technology has been helping the Federal Highway Administration, in cooperation with the American Association of State Highway and Transportation Officials, to assure the safety of hundreds of truss bridges across the United States. Iadicola has been testing the use of a thoroughly modern version of an old technique — photographic measurement or "photogrammetry" — to watch the failure of a key bridge component in exquisite detail.

Developing and adopting innovative technologies to solve America's transportation challenges takes time and money. But before that, we need outstanding research. And where better to do research than the many respected universities spread across the country? More Work zone safety: Protective services Roads&Bridges Magazine Share ![]() ![]() ![]()
When you get down to it, roadside safety is about minimizing negative impacts in some cases, quite literally. It is about reducing the probability for harm by introducing positive factors into the equation. For example, effective planning, improved technologies and behavioral modification all play key roles in maximizing roadside safety. Safety in work zones is no different. More Concrete barrier, parapet pavers enhance highway safety Construction Equipment Magazine Share ![]() ![]() ![]()
Although the practice of using a concrete barrier down the center of a roadway to separate opposing traffic dates back to the mid-1940s, the practice seems really to have gained steam when, in 1955, the state of New Jersey began using an 18-inch vertical concrete wall in the median of major highways. But the Jersey has competition, which means that paving contractors who might install barriers and bridge parapets in several states usually have a substantial investment in molds. More Work Zone Road User Costs Concepts and Applications Transportation Research Board Share ![]() ![]() ![]()
The U.S. Federal Highway Administration's Office of Operations has released a report that provides information on work zone road user cost components and concepts. The report also addresses their application in selecting the preferred maintenance of traffic alternatives, project delivery/contracting strategies, and benefit-cost analysis. Work zone road user costs are designed to help provide the economic basis for quantifying adverse work zone impacts. More 3 political challenges to enacting transportation bill by March 31 Transportation Issues Daily Share ![]() ![]() ![]()
SAFETEA-LU, the federal surface transportation bill, expires on March 31. Enacting a bill by then requires quickly overcoming big political challenges (e.g., how to fund the bill) and procedural challenges (e.g., deadlines for committees to act.) Incidentally, overcoming those challenges and enacting a bill could significantly increase the positive image of Congress. More |
