Performance of Recycled Asphalt Concrete Materials in an Arid Climate
Recycling of asphalt concrete pavement is a common practice for highway agencies. In 1981, the Arizona Department of Transportation (ADOT) constructed eight test sections in on experimental...

Performance of Free Draining Base Course at Fort Campbell, Kentucky
In 1990 a free draining base course layer was constructed in the structural section of a pavement to be used as a military vehicle maintenance yard at Port Campbell, Kentucky. The Corps...

Reliability-Based Design for Feeeze-Thaw Concrete
Observation of pavements in Iowa shows results from the test for freezing and thawing of concrete, ASTM C-666, is not always consistent with field performance. Similar concrete made with...

Sprayed-Zinc Galvanic Anodes for the Cathodic Protection of Reinforcing Steel in Concrete
Corrosion of reinforcing steel bars (rebars), due to penetration of chloride ions from seawater affects the substructure of many bridges in marine service. In a new, low cost control method,...

Evaluation of Partial Depth Spall Repair Materials and Procedures
In 1990, as a part of a Strategic Highway Research Program project (SHRP H-106, Innovative Materials Development and Testing), an investigation was initiated to evaluate the performance...

Seattle Plays It Safe
To ensure the reliability of its aging water system in a major earthquake, the Seattle Water Department commissioned a comprehensive assessment of the system's seismic reliability...

Earthquake Hazard Investigative Procedures for Central United States Waterworks
The vulnerability assessment of Central United States waterworks for earthquake hazards is a developing engineering practice for civil engineers in Arkansas, Missouri and states close...

Seismic Mitigation of the Memphis Water System
Memphis, Tennessee is located in zone 2 of the 1988 Standard Building Code, close to the New Madrid Seismic Zone. The probability of having a seismic event of significant magnitude is...

Seismic Hazards in the Eastern U.S. and the Impact on Transportation Lifelines
In the eastern US seismicity is low, hazard is moderate, and risk is quite high, especially in metropolitan regions with vulnerable transportation systems typically not designed to resist...

Evaluation of Seismic Vulnerability of Highway Bridges in the Eastern United States
For high risk seismic zones such as California, the state-of-the-art in earthquake resistant design for new highway bridges has been well advanced, especially since the damaging 1971 San...

Transportation Lifeline Losses in Large Eastern Earthquakes
In December 1991 Applied Technology Council (ATC) and its subcontractor, EQE Inc., completed a 2-year Federal Emergency Management Agency-sponsored study to assess the seismic vulnerability...

Regional Evaluation of Transportation Lifelines in New York State with the Aid of GIS Technology
Regional evaluation of transportation lifeline facilities which may be impacted by seismic and other natural hazards is of great concern for purposes of emergency planning and response...

Seismic Hazard Along a Central U.S. Oil Pipeline
An integrated approach is used to evaluate seismic hazards at six sites where pipeline 22 crosses the major rivers in West Tennessee. On the basis of historical and instrumental data,...

Migration of Spilled Oil from Ruptured Underground Crude Oil Pipelines in the Memphis Area
This study evaluated the impact of an oil pipeline rupture in the recharge area of a West Tennessee aquifer. Two potential break locations were chosen in the alluvial valley of a main...

Earthquake Countermeasures for Lifelines in the Central and Eastern United States
Seismic hazards affecting petroleum transmission systems in the Central U.S. and water and gas distribution systems in the Eastern U.S. are discussed. Experience during previous earthquakes...

Ports '92
This is a collection of the technical papers presented at the Ports '92 Conference held in July 1992 in Seattle, Washington. Initiated in 1977, this Conference is the sixth...

Dallas Goes Trenchless
Dallas Water Utilities (DWU) has stopped relying solely on traditional open-cut trenching methods. Instead, we look to trenchless technologies to minimize costs and disruption to the public....

Wave-Current Interaction with a Large Structure
The effects of a current on the diffraction of regular waves around a three-dimensional body are examined by a time-domain method. The Froude number is assumed to be small so that the...

Experimental Studies for the Port of Bilbao Extension
The Port of Bilbao is the leading port in Spain concerning total traffic volume. It also holds a relevant position in the international context. The Managing Board recently approved an...

The Mother of All Resilient Structures: Fixed-Base Tower in 3000-Foot Water and Some Outstanding Issues
This paper describes design and development work for 40- to 80-well fixed- base - yet compliant - towers for 2000- to 3000-foot water depths. Technical issues which are covered include:...
