Special Geotechnical Testing: Central Artery/Tunnel Project in Boston, Massachusetts
The Central Artery/Tunnel Project (CA/T) in Boston, Massachusetts, is the largest urban highway construction project in the history of the interstate system. The magnitude and complexity...
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....
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...
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...
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...
Alaska's Last Link
Alaska's Seward Highway has been upgraded this past year. The last section of the highway dates back to the state's early mining days in the Kenai Peninsula,...
Fathoming the Strength of Structures
More and more, the owners of bridges and piers are budgeting rehabilitations based on inspections done underneath the waterline. Increasingly, they want the underwater inspectors to be...
Design of Blast Resistant Buildings in Petrochemical Facilities
This report provides general guidelines in the structural design of blast resistant petrochemical facilities. Informational coverage is provided for OSHA requirements, design objectives,...

Unsaturated Soil Engineering Practice
This collection of papers presented at the sessions on Unsaturated Soil Engineering Practice held during the First National Conference of the ASCE Geo-Institute at the Utah State University...
Old Aswan Dam
Egypt's Aswan Dam is almost 100 years old, and engineers performed tests of the masonry, conducting petrographic and chemical analyses. The High and Aswan Dam Authority of...
Telling Florida's Water Story
The latest addition to the nation's family of aquariums is Tampa's recently completed Florida Aquarium. The $84 million 152,000 square foot cast-in-place concrete...
Mixing Influences on Cement-Based Waste Forms
High-shear, medium-shear, and low-shear mixing tests were conducted on paste and paste + fly-ash mixes: The specimens, cured for 28-days, were tested for free water generation, compressive...
