|The study will evaluate the fresh and hardened properties, durability, and
in-situ performance of roller compacted concrete (RCC) for pavement applications. This will be the first project of this kind in Mssouri and may pave the way to greater use of this sustainable and cost-effective material in the future. The study will involve and extensive laboratory investigation and field implementation of RCC technology. The results from this study will
provide feedback to future field implementation of this technology in transportation-related infrastructure.
|Roller-compacted concrete (RCC) is a concrete of no-slump consistency in
its unhardened state that is typically transported, placed, and compacted using asphalt, earth and rock fill construction equipment. The constituents are the same as for conventional concretes but the mixture proportions differ in that the aggregate grading and content has to be such that the RCC can immediately take load. RCC is can be design to develop compressive and flexural strengths in the range associated with structural concrete. The proposed research study will evaluate the fresh and hardened properties, durability, and in-situ performance of RCC. Optimized RCC formulation will be used for widening Route 142 in Doniphan, Missouri. Fieldcast concrete will be extensively sampled and tested to compare its performance to conventional concrete used in pavement construction. The structural health monitoring of the performance of the pavement will also be determined. The results from this study will provide feedback to future
field implementation of this technology in transportation-related infrastructure.

Technology Transfer Activities
|The technology transfer activities will include a final research report and dissemination of the findings through a national conference via technical
presentation(s) and publication(s).
|Monthly updates will be provided to the MoDOT primary contact assigned to this research project. Quarterly reports will be submitted on or before the last working day in August 2013, November 2013, February 2014, and May 2014 during the course of the project.
The study will be the proposal of guidelines for evaluating, selecting, and specifying RCC. These guidelines will provide both MoDOT and design engineers with a resource to design, test, and implement RCC in transportation-related infrastructure.
