The Transrapid EMS Maglev System
The Transrapid 300 mph (500 km/hr) magnetically levitated transportation system is ready for revenue application. The maglev system uses contactless electromagnetic suspension and three...
Controlling Corrosion in Bridge Structures
The overall objectives of the Structures Research Area of the Strategic Highway Research Program (SHRP) were to provide methods to protect chloride-contaminated concrete components against...
Long-Term Pavement Performance Program for Years 1992-1997: A Strategic Plan
The Federal Highway Administration (FHWA) began operational management of the Strategic Highway Research Program's (SHRP) Long-Term Pavement Performance (LTPP) program on July 1, 1992....
Validation of SHRP Performance Graded Binder Specifications Using Field Simulation Testing Equipment
The Strategic Highway Research Program (SHRP) was initiated to improve the effectiveness of laboratory test methods in predicting field performance. European highway agencies are using...
How SHRP Reliably Predicts Pavement Performance
One of the important results of the SHRP Asphalt Research Program was to develop a comprehensive pavement performance model that reliably predicts rutting, fatigue cracking and thermal...
Modified Graphite Reference Electrodes
The primary aim of this research was to investigate the feasibility of developing an improved, more reproducible, reversible, and highly voltage invariant graphite reference half cell...
Future Improvements for Design of Flexible Pavement Structures
The first set of data analyses on the National Pavement Data Base (NPDB) derived from the Long-Term Pavement Performance (LTPP) activities have been completed. The results from sensitivity...
Cathodic Protection for Protecting Prestressed Concrete
Due to the good effect of corrosion protection of reinforcing steel bars, even in concrete highly chloride contaminated, cathodic protection for concrete structure now carried out as a...
Long-Term Pavement Performance (LTPP) Program in Japan
Japan's `Manual for Design and Construction of Asphalt Pavement' is based on technical results from the AASHO Road Test in 1960's. Strategic Highway Research Program (SHRP) is a much bigger...
Influence of Lateral Wind on Driving on Offshore Bridge
The Honshu-Shikoku Bridges are a system of highways crossing over the sea, where cross-winds variously affect vehicle behaviour. This is the intermediate report on the surveys aimed at...
Traffic Accident Analysis System
While statistical data on traffic accidents are invaluable in devising effective traffic safety measures, the number of data items and samples are vast and they must be processed and edited...
SNCF High-Speed Trains: 15 Years of Design, 13 TGV Generations
Less than ten years after the first high-speed revenue service, SNCF has just placed an order for a third generation of TGV rolling stock: the double-deck TGV. Between two generations,...
SHRP Deformation Test?Asphalt Mix Tests and Analysis Systems
From analyses of existing information on the permanent-deformation characteristics of asphalt/binder-aggregate mixes, as well as the development of permanent deformation in pavement structures,...
Early Field Experience with SUPERPAVE
Specific pavement studies of newly constructed, reconstructed or rehabilitated (resurfaced) pavement sections were used to provide an estimate of the relative influence of key pavement...
Changes to the AASHTO Guide for Design of Pavement Structures
At this juncture of the SHRP-LTPP program, it is appropriate to discuss the potential impacts that SHRP-LTPP results could have on the future AASHTO Guides for the Design of Pavement Structures....
Rehabilitation/Upgrading of Under-Rated or Deteriorating Single or Multi-Span Structures Using Corrugated Steel Pipe, Tunnel Liner Plate or Structural Plate
This paper cites advantages of the rehabilitation/upgrading of under-rated or deteriorating culverts or bridges using corrugated steel pipe, tunnel liner plate or structural plate. Among...
Computer-Aided Liability
Civil engineers are using computers more than ever to help them streamline analysis and design, boost productivity and cut costs. Often they rely on mass-marketed software such as Autodesk...
Some Considerations for the Use of Geographic Information Systems
GIS have become widely used. Geotechnical earthquake engineers need both to understand what distinguishes a GIS form other data base systems and to make clear the purpose, use, and maintenance...
Liquefaction Potential of Western Puerto Rico
The historical seismic record, paleoseismic evidence, high population density, time expired since the last major earthquake, and the presence of liquefiable sands and soft clays combine...
Development of Geographical Information System (GIS) for Seismic Hazard Study of Charleston, SC
One of the most prominent areas of seismicity in the eastern U.S. is near Charleston, SC. The 1886 Charleston earthquake (M=7,5) and liquefaction evidence from at least five prehistoric...
