The American Public Works Association will host a webinar on the future of asset management on Thursday, June 27, from 11 a.m. to noon Eastern Time. The presentation will discuss the new and interesting ways that organizations are using technology to solve problems, become more efficient, and save money. In addition, presenters will forecast what technology can be integrated into current systems and envision what new technology is necessary to fully automate processes.

Researchers for Virginia DOT investigated the reasons for premature failure of concrete patches on continuously reinforced concrete pavement. Testing revealed that the use of high early strength mixes with high cement contents and failure to assess the overall pavement condition were the most frequent causes of early patch failure. The study recommended revisions to VDOT’s concrete patching procedures.

Vermont Agency of Transportation recently tested a lower-cost pavement maintenance approach, repaving a 40-inch-wide area along the right wheel path in each direction of a deteriorated roadway rather than repaving the entire surface. The treatment was successful, reducing rutting and cracking and extending the pavement’s service life.

The Transportation Research Board will conduct a webinar about the applications of continuous pavement deflection technology on Thursday, May 30, from 1:00 to 2:30 p.m. Eastern Time. The ability to collect information on pavement structural capacity at traffic speeds is changing how agencies evaluate their pavement needs. This webinar will explore how agencies can conduct pavement assessments effectively and will compare continuous deflection to traditional methods of assessing pavements.

Researchers for Minnesota DOT and the Minnesota Local Road Research Board have developed a spreadsheet tool to help local agencies effectively track and manage gravel roads. Designed to be flexible and customizable, the tool can be used to keep all maintenance and construction data about a gravel road system, as well as track costs.
