With most States planning to implement the Superpave system within the next 2 years, highway agencies and industry are starting to wonder where they'll find enough engineers trained in the Superpave mix design procedures. To meet that need, five Florida universities have teamed up with the Florida Department of Transportation (DOT) and the Federal Highway Administration's (FHWA) Florida Division to make training on the Superpave system available to undergraduate students.
Since its beginning more than a decade ago, the long-term pavement performance (LTPP) program has collected enough data to fill more than 40,000 floppy disks. While most of the data are complete and accurate, analyses indicate that some gaps exist and some of the data do not meet quality control standards. So this summer, the Federal Highway Administration (FHWA) is holding meetings with highway agencies in States and Provinces to develop plans for addressing those gaps and questions about quality.
Spending a little money today on a well-planned preventive maintenance strategy can keep pavements in good shape at a much lower cost than repairing or rehabilitating pavements after they begin to fall apart. It can be hard, however, to get that message to the people who hold the purse strings. A new videotape from the Michigan Department of Transportation (DOT) and the Federal Highway Administration (FHWA) helps deliver the message.
It's been described as the world's biggest Tonka truck, but the remotely driven shadow vehicle (RDV) is no toy-it's a potentially lifesaving tool for highway maintenance crews. Since being assembled under the Strategic Highway Research Program (SHRP) using an idea from the Minnesota Department of Transportation (DOT), the prototype RDV has performed well in work zones and demonstrations.
The Wyoming Department of Transportation (DOT) is no stranger to snow fences. For nearly 30 years, the highway agency has been using snow fences to prevent blowing and drifting snow from covering roads and impairing motorists' ability to see other vehicles. Despite all this experience, it's still difficult and time-consuming for DOT staff to determine exactly which sections of road will be affected by blowing and drifting snow.
