The main objective of this research is to develop a ultra high performance concrete (UHPC) as a reliable, economic, low carbon foot print and durable concrete overlay material that can offer shorter traffic closures due to faster construction and long-term service life. This project aims at maximizing the performance of a thin layer of pavement material by reaching to an optimized composition of SCMs and proper types and amounts of fibers. Quarterly Progress (Apr-Jun 2016): The Task Order was executed by Missouri Department of Transportation (MoDOT) on July 8, 2016. Federal Regulations changed on June 30, 2016, which has caused a change in the F&A rate to go from 52.5% to 55%. This change will be documented via a letter that includes a new budget document. There will not be a formal supplemental agreement executed.
