Implementation of Ultra-High-Performance Concrete (UHPC) Bridge Deck Overlays in Nebraska

The Nebraska Department of Transportation (NDOT) Project SPR-FY24(034) confirmed the superior mechanical and durability performance of Nebraska’s non-proprietary ultra high performance concrete (UHPC) mixtures, field implementation remains a critical missing step. Bridge deck overlays require substantially larger material volumes and longer placement durations than typical UHPC applications, such as joint connections or patch repairs. These factors introduce challenges in production logistics, equipment capacity, and quality control that must be validated under real construction conditions. Currently, NDOT and local contractors lack documented field procedures and specifications tailored to Nebraska’s climate, materials, and construction practices. Key uncertainties remain regarding surface preparation methods (e.g., milling versus hydrodemolition), on-site batching and mixing of large quantity using truck mixers, placement sequencing, construction joints, finishing, curing, and early-age strength verification. Without full-scale field demonstration and training, these unknowns limit NDOT’s ability to specify UHPC overlays in new or rehabilitation bridge projects.
