Birdbaths: Expectations vs. Reality
Descripción: The project’s done. It’s time to close it out. Should be easy. However, a final washing of the floor leaves a few birdbaths - puddles of water.

Conductive-Concrete Overlays
Descripción: Bridge decks are prone to ice accumulation, making winter travel treacherous. Road salts and some other deicing chemicals are cost effective, but may cause surface scaling, reinforcing-steel corrosion, or both. Another alternative is a thin, conductive-concrete overlay that, when connected to a power source, can generate enough heat through electrical resistance to prevent ice formation on the deck or melt ice after it forms.
Using a conductive concrete overlay provides an environment-friendly deicing method that would prolong bridge service life by significantly reducing the use of road salt and deicing chemicals.

Construction of the My Thuan Cable-Stayed Bridge
Descripción: The My Thuan Bridge is the first cable-stayed bridge in Vietnam and the second crossing over the Mekong River. The 23.6 m (77.5 ft) wide in-place concrete deck is supported by two planes of stay cables anchored from two H-shaped towers 120 m (394 ft) high.

In-Place estimation of concrete strength during the construction of a highway bridge by the maturity
Descripción: The maturity method was used as an in-place technique for the determination of compressive strength during the construction of a highway bridge at the intersection of Interstate-78 and state highway 21 in New Jersey. The objective was to demonstrate the feasibility for using the maturity method in future New Jersey Department of Transportation (NJDOT) projects. The 28-day cylinder strength did not closely represent the in-place concrete strength or include the effects of placement, and curing operations, and a more rapid procedure was needed to proceed with critical construction operations. This project served as a pilot for subsequent establishment of Departmental training and procedural operations for the construction of concrete structures.

Stress ribbon and suspension bridges with precast segmental deck
Descripción: Stress-ribbon and suspension pedestrian bridges are described in terms of their structural solution, the process of construction, and the influence of the structural arrangement on the static and dynamic analysis. Both types of bridges have a very slender deck assembled from precast members formed by two edge girders stiffened by transverse ribs. . .
