Ultra-High Performance Concrete | FHWA

Dec 02,  · This Wapello County, Iowa, structure was the first UHPC bridge constructed in the United States. The bridge includes three UHPC prestressed I-girders spanning a creek in rural Iowa. Ultra-high performance concretes have demonstrated exceptional performance when used as a field-cast closure pour or grout material in applications requiring the onsite connection of multiple prefabricated elements.

Polymer-modified Mortars| Concrete Construction Magazine

The first thing to understand is that polymers are primarily used to modify mortars (portland cement + water + sand aggregate), not concrete (mortar + larger aggregates such as gravel or stone), due to the relative cost involved. The main exceptions are polymer-modified concrete for bridge deck overlays and road repair work.

Monroe County Suder Road Bridge. A few years after installation the MDOT project had issues with the field installed joints in the concrete deck. The concrete deck joints were specified by MDOT utilizing a welded lateral bridge connection and non-shrink cementitious grout. The joint experienced leaching of water and chlorides through this joint.

The impact echo test (IE) is a common NDE technique that relies on the acoustic resonance response of bridge decks to detect subsurface delaminations that can lead to spalling. However, IE data interpretation is largely done manually and the connection between the IE results and CR is not fully explored.

Minor hairline cracking was observed in the UHPC and adjacent conventional concrete deck. The final objective of the research was to provide review and advisement to ODOT related to the GAL 160-18.84 UHPC deck panel connections. The deck panels were to be full width except near the bridge ends due to the high 35o skew.
