Truck Weight Enforcement on a WIM
Pavements on interstate highways and other major truck routes are deteriorating faster than predicted. The cause is largely the larger-than-predicted number of the heaviest, 5-axle trucks....
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...
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...
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...
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...
How to Use a Transit Consumer Information System
This paper reports the results of an effort to implement a consumer information system in a small urban area. The system was designed to periodically report the travel patterns and viewpoints...
Performance Analyses and Design for Urban Bus Transit
This paper describes a Management approach to Bus Transit Systems based on the treatment of Demand, Supply and Policy. The procedure described is currently supported by a series of interactive...
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...
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...
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...
Tunnel and Bridge Construction with Minimum Disturbance to Overhead Services
The rapid growth of pipe jacking over the last 20 years and the improvement and development of methods in terms of lengths of drive, size and ability to work in varying ground conditions...
Financing the Golden Gate Bridge?Past and Present
This paper discusses the financial side of the project, which was a very innovative solution that provided federal revenue not only for the Bridge Redecking Project, but more importantly...
China Builds Record Bridge
China's Hanjiang Railway Bridge has a 1,000 ft (305 m) long main box girder and is the longest bridge of its type in the world. The steel box girder bridge is built with a...
Effects of External Loadings on Large-Diameter Buried Pipelines
Development of oil and gas resources in the far north has involved extensive use of buried steel pipelines. Buried pipelines, particularly onshore, are frequently subjected to heavy superimposed...
Soil-Pipeline Interaction During Ground Movement
The problem of the elastic interaction is examined between a pipeline or a group of connected flexible connected pipelines and the surrounding soil medium, which is induced by ground movement....
Pile Creep Designs for Frozen Layered Profiles
A concept of relative creep stiffness suitable for the evaluation of the long-term, uniform creep behavior of non-ice type, frozen soils is presented. This concept extends the current...
Creep Rate Analysis of Pile Load Test Data
The uniform creep behavior of five driven piles and one slurried pile based on pile load test data are presented and analyzed. The incremental static load tests carried out by ARCO, Alaska...
