Bridging the Joints in Bridges
Most bridges are designed with gaps in them. The cracks allow bridges to expand and contract as the temperature changes. But water can enter these gaps and foul bearings and structural...
Steel Bridge Counterattack
In bridges, for years steel has been losing market share to concrete, but now the steel industry is making an impressive comeback. One reason is use of load-factor design, which has cut...
Filling the Cracks
Engineers, highway officials, and manufacturers are working together to develop new products to rehabilitate cracked bridge decks. Polymer concrete overlays are among the many remedies...
Shopping for a New Bridge Coat
Total shop coating of new steel bridges appears to be the best armor against corrosion. This alternative is one of three techniques for diminishing the difficulty and expense of painting...
Celebrating a Conquest
During construction of the San Francisco-Oakland Bay Bridge, which marked its 50th anniversary on Nov. 11, 1986, great public attention was paid to the high-climbing steelworkers, but...
Designing for Flow
Geotextiles used for in-plane drainage can carry surprisingly large amounts of water within their structures. These composite drains, known as sheet drains, prefabricated drainage composites...
Designing for Shock Resistance
If a product or structure is subject to shock loadings, and is unable to take them without unacceptable damage, it must be insulated from the shock. The decision may be to redesign the...
Jet Grouting: Snail's Pace of Adoption
Jet grouting is grouting of soil, but the process, the equipment and the subsurface product are different from the familiar ones. Here the cement grouting is mixed in situ with the surrounding...
Spreadsheets: A New Design Tool
New techniques are developing which make computer programming easier. One new technique is spreadsheet programming for microcomputers. Two programs are presented which give a quick overall...
Nuclear Waste Handling and Storage
These papers examine a number of topics related to handling and storage of nuclear wastes and spent fuel as well as some topics related to transportation and long term disposal of nuclear...
Application and Performance of Structural Materials and Exterior Facades
The papers in this book present some of the current thinking associated with today's construction materials as well as the results of research which is directed toward the...
Research on Transportation Facilities in Cold Regions
Transportation facilities research in cold regions, reported in this session proceedings, begins with a field study showing that ground surface characteristics have a significant effect...
Experimental Assessment of Performance of Bridges
Among the papers in this book, five assessed the global bridge behavior and the three concentrated on bridge decks. The bridges assessed include prestressed steel plate girder and truss...
Pavement Management Systems for Urban Areas
Pavements represent the largest public investment for most urban-area governmental jurisdictions. The magnitude of this investment requires that the expenditure of funds to maintain pavements...
Use of Private Contracting in Highway Maintenance
Managing the business of highway and bridge maintenance in this country is largely a function of the public sector. As in the private sector, economic realities during the past decade...
Life Cycle Analysis
Of all the infrastructure elements, pavement performance has probably received more research than any. Similarly, there has been more application of pavement research. The concepts that...
Infrastructure Management and Planning for the City of Seattle
This paper summarizes the current planning effort that the City of Seattle's Engineering Department (SED) is undertaking for Transportation Infrastructure Management. The...
The United States Used to be a Great Country...
Up until 20 years ago, the American highway departments did a good job of maintaining bridges and they kept streets well paved. The public works departments maintained the water and sewer...
Earth Retention & Noise Absorption Using Evergreen Planted Walls
There is a new concept in wall design used for retaining walls, free standing noise absorbing walls and rock revetments. The Evergreen System is comprised of large prefabricated concrete...
Golden Gate Bridge: Deck Replacement
A major inspection of the Golden Gate Bridge in 1968-69 found the reinforced concrete roadway of the Bridge to have widespread defects and local failures. Further investigations found...
