The concrete industry has an array of options when it comes to recycling. Incorporating glass, chicken feathers, palm fronds, sludge, crushed computer casings or other recycled materials...
Probing Pipelines (available only in Geoenvironmental Special Issue)
Inspecting underground pipelines has become easier, more effective and less intrusive through use of sonar, radar, lasers and seismic and acoustic testing. To replace simple visual inspection,...
Framing a Work of Art
One of the most visually unique building designs of the twentieth century, the Guggenheim Museum project in Bilbao, Spain, required an innovative structural engineering solution and pioneering...
Casting Hot and Cold
Contractors and engineers battled the Minnesota winter to build a concrete segmental bridge with form travelers. Superstructure segments were poured in temperatures as low as -19F, using...
Rock Dam Revitalization
Sometimes restoring an area to a natural appearance requires a little artificial help. When the city of Longmont, Colo., began creating the St. Vrain Greenway, a park and recreation area...
Climate Control
The Wisconsin Department of Transportation (WisDOT) has created its own customized weather information system to improve efficiency in its winter road maintenance operations. Intended...
The Search for HPC (Available in Structural Engineering Special Issue only)
High-performance concrete (HPC) is often overlooked by engineers because its properties are not well documented. Concrete Clinic International conducted a study to learn more about the...
Shake It Up (Available in Structural Engineering Special Issue Only)
The California Department of Transportation (CALTRANS) has used structural lightweight concrete for more than 45 years in bridges across the state. Lightweight concrete�made with aggregates...
Behavior of Construction and Demolition Debris in Base and Subbase Applications
The design performance of a pavement system is evaluated based on the predicted number of load repetitions it will be subjected to throughout its service life. Mechanistic pavement design...
Repeated Loading of Stabilized Recycled Aggregate Base Course
The fatigue behavior, resilient properties, and progressive accumulation of damage due to repeated flexural loads on a fiber-reinforced pavement base course material composed of cement-stabilized...
Database on Beneficial Reuse of Foundry By-Products
This paper describes a database on beneficial reuse of foundry by-products that was assembled at the University of Wisconsin-Madison. The database was designed to identify (1) materials...
