Roller Compacted Concrete - Ripley County Rt 160

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 can be designed 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.
