Use Ultra-High-Performance Fiber-Reinforced Concrete (UHP-FRC) for Fast and Sustainable Repair of Pavements

This project offers a new methodology which will enable the use an advanced fiber-reinforced concrete material which will delay or prevent the deterioration of transportation infrastructure when subjected to traffic and environmental loadings. The major concern regarding concrete structure is the considerable deterioration and consequent repair work needed due to its brittleness and limited durability. The consequence of concrete deterioration and short service life requires frequent repair and eventual replacement, which consumes more natural resources. Ultra-high-performance fiber-reinforced concrete (UHP-FRC) introduces significant enhancement in the sustainability of concrete structures due to its dense microstructure and damage-tolerance characteristics. These characteristics can reduce significantly the amount of repair-rehabilitation-maintenance work and give transportation infrastructure longer service life, all of which will eventually lower the environmental liability of concrete use. This research will address the strong need to develop fast and sustainable repair UHP-FRC materials for concrete pavement repair that can be easily cast on-site without special treatments such as heat, pressure, and vacuum. This avoids any major changes to current concrete production practice to accelerate the use of UHP-FRC materials for pavement repair.
