Over the Top Concrete
The 60-year-old Tongue River Dam in southeastern Montana is undergoing extensive dam safety and reservoir enlargement modifications. Major features of the project include a 60,000 cfs...
Concrete Change
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...
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...
Making the Grade
A new grade of high performance steel, HPS-70W, allows engineers to design tougher, lighter structures. The high performance weathering steel has a yield strength of 70 ksi, or 485 MPa....
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...
Stretching a Landfill
Landfill expansions can pose engineering challenges, and the Tullytown, Pa., landfill gives an example of a horizontal expansion that added 121 acres of future disposal space. The side-by-side...
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...
Paper Mill Sludge Landfill Cover Construction
A considerable amount of experience has been acquired from a number of completed paper mill sludge landfill covers within the United States. This paper focuses on practical guidelines...
Geotechnical Performance of a Highway Embankment Constructed Using Waste Foundry Sand
A highway embankment was constructed near Auburn, Indiana, using waste foundry sand (WFS) as a demonstration project for the Indiana Department of Transportation (INDOT). Laboratory testing...
Utilization of Lagoon-Stored Lime in Embankment Construction
The maximum percentage of lime that can be mixed with a predetermined borrow material to build the proposed road embankment without adversely affecting the physical and mechanical properties...
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...
Role of Constituents on the Behavior of Flowable Fly Ash Fill
Flowable fills are increasingly used as backfill materials for pipes and retaining structures because of ease of placement and performance of the solidified material. But the role of its...
The Safe Disposal of Fly Ash in Pavement or Earth Structures Not Requiring High Strength Materials
Highway agencies throughout the country face the challenge of safe disposal of various waste products in pavements and earth structures. Some of these waste products can be hazardous to...
Crushed Hydrated Fly Ash as a Construction Aggregate
Hydrated fly ash (HFA) is being produced in Texas by first adding water to Class C fly ash and allowing it to hydrate in curing pits for several weeks. HFA typically attain unconfined...
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...
