Brief Description of Research Project

This study aims at developing sustainable concrete materials for infrastructure applications. The main idea is to develop a cost effective and sustainable ultra-high performance fiber-reinforced concrete to be used in concrete infrastructure applications where enhanced durability and extended service life are key. The main emphasis for this concrete is its use focusing on bridge, approach slab and pavement joint detailing and other areas where high durability and ductility demands are required.

Describe Implementation of Research Outcomes

 Lab work will include the development of UHPC mixes using locally available materials. These more cost effect locally developed materials will be used in joint continuity studies, ultra-thin overlay on rigid and flexible pavements, and ultra-thin stay-in-place formwork. At the conclusion of this study, these systems will be ready for implementation by any bridge or highway owner.

Impacts/Benefits of Implementation

Provide USDOT/FHWA and state DOTs with a viable and economical locally developed UHPC and laboratory results on three possible infrastructure applications.
