Did you know Iowa DOT Research is always working to explore new ways to make transportation safer, more efficient, and cost-effective? Learn more about some of our research efforts currently in progress:
VKelly Slipform Paving Test. The Vibrating Kelly Ball (VKelly) test may be a viable option for measuring the consistency of a pavement mixture onsite before road work begins. To ensure the test produces accurate and reliable results, Iowa is leading a multi-state study to outline the step-by-step process, simplify the testing equipment, and develop guidance for test operators. The study is expected to conclude in March 2025. Subscribe and receive project updates here.
Bridge Strike Detection and Reporting. When a vehicle hauling an oversized load strikes a bridge, it can cause significant damage and decrease the bridge’s life expectancy. Drivers often don’t stop or report the incident, leaving authorities unaware of the damage and taxpayers on the hook for repairs. To make sure damage is paid for by the offender, Iowa DOT is piloting a first-in-the nation research project to detect bridge strikes in real time and match the data with vehicle records. The research is expected to conclude in June 2024. Subscribe and receive project updates here.
