The latest issue of the Concrete Bridge Views newsletter (Issue 78, Sept/Oct 2014) is now available online. Articles include:
- Dimensional Stability of Cementitious Grouts in Prefabricated Bridge Connections – Ensuring Good Performance, Igor De la Varga, FHWA, Zachary B. Haber, FHWA, Benjamin A. Graybeal, FHWA. The majority of accelerated bridge construction projects rely on using prefabricated bridge elements and systems to meet tight construction windows. These systems commonly depend on field-cast cementitious grouted connections between elements for structural continuity.
- Low-Cracking High-Performance Concrete Bridge Decks, David Darwin, University of Kansas. Research dating back more than 25 years has established the key factors that control bridge deck cracking – age, bridge deck type, concrete material properties, site conditions, curing and even date of construction.
- Reducing Steel in Bridge Decks, John M. Holt, P.E., Texas Department of Transportation, Amy Smith, P.E. Texas Department of Transportation. The most structurally taxed element in a bridge is its deck. It receives constant pounding from heavy truck wheels and is the element most exposed to the environment.
Concrete Bridge Views is published jointly by the Federal Highway Administration and the National Concrete Bridge Council. Click here to access the issue and each article summarized above.
