Field Implementation And Monitoring Of An Ultra-High Performance Concrete Bridge Deck Overlay, Craig Newtson, Brad Weldon, William Toledo, Andres Alvarez, Mark Manning

Data

This project focused on field implementation of an ultra-high performance concrete (UHPC) overlay during rehabilitation of an existing concrete bridge (No. 7032) deck in Socorro, New Mexico, USA. Bridge 7032 is a two-lane bridge that is approximately 300 ft. (91.4 m) long and 54 ft. (16.5 m) in width. Rehabilitation of bridge 7032 included removal of deteriorated concrete from the existing deck, installation of a high-performance deck (HPD) leveling course, and installation of a 1 in. (25 mm) UHPC overlay. An UHPC mixture with a 19.5 ksi (134 MPa) compressive strength developed in previous research was selected for this project. …

Bridge Deck Inspection Using Small Unmanned Aircraft Systems Based Airborne Imaging Techniques, Su Zhang, Shirley Baros, Susan Bogus

Data

As one of critical components of a transportation infrastructure system, bridges are very important to a country’s economy because they provide passage over physical obstacles to substantially reduce travel time and travel cost. Similar to other types of transportation infrastructure, bridges deteriorate over time. Therefore, bridges should be routinely inspected to ensure their serviceability, capacity, and safety under current traffic. Subsequently, transportation agencies at all levels (e.g., federal, state, local, and tribal) dedicate large amounts of time and money to routinely monitor and inspect bridge conditions as part of their infrastructure asset management programs. These transportation agencies use the collected …

Bridge Deck Overlays Using Ultra-High Performance Concrete, Craig Newtson, Brad Weldon

Data

Corresponding data set for Tran-SET Project No. 17CNMS01. Abstract of the final report is stated below for reference:

"This study investigated the use of a locally produced ultra-high performance concrete (UHPC) as an alternative to typical overlay materials. Several bond strength tests including slant-shear, splitting tension, and direct tension tests were performed to assess the bond strength between UHPC and normal strength concrete (NSC) substrate with varying surface textures. Tests were also conducted to assess the early-age and longer-term shrinkage behavior and coefficient of thermal expansion of the UHPC as well as rapid chloride permeability testing. Good bond between UHPC …
