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....
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...
A Geotechnical/Earthquake Engineering Information System?Expanding the GIS Conceptual Framework
Data in a typical geotechnical and earthquake engineering study, encompass a variety of sources of information from site investigations, field instrumentation, dynamic computer simulations,...
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...
State of the Art in Spatial Data Transfer: FIPS 173
This paper provides an overview of Federal information processing standard (FIPS) 173. FIPS 173 is a comprehensive spatial data transfer standard that provides solutions to the problem...
Towards a Common Data Exchange Format Between Geographic Information Systems
To make their respective geographic information systems (GIS) software packages more useful to the user community, the GIS software vendors have steady added various database translators...
Digital Image Processing: Experiences in the Gulf War
During the 1990-91 conflict in Southwest Asia between Iraq and coalition forces operating with US Armed Forces, the utility of products developed from digital imagery and digital terrain...
Digital Image Processing and Analysis in Materials Science (Keynote Lecture)
This discussion presents a generic overview of computer aided imaging in materials science. Some of the questions to be answered are: Does the computer perceive the same things that I...
Multispectral/Hyperspectral Imaging and Data Compression
Remote sensing instrumentation, data and analysis techniques for Civil Engineering applications are similar to those used in multidisciplinary remote sensing of the earth's surface. Data...
Digital-Image-Based Computer Modelling of Cement-Based Materials
Understanding the relationships among materials, processing, microstructure, and properties is critical in improving material design. This paper outlines an approach for furthering this...
Characterization of Man-Made Vitreous Fibers by Image Analysis
This paper deals with the characterization of man-made vitreous fibers (MMVF), seen as an application of the techniques of image analysis and mathematical morphology. We present the whole...
Morphological Methods for Characterizing Inter-feature Distances
Characterizing inter-feature distances in digital images using automatic image analysis systems presents problems not found when quantifying the morphology of the features themselves....
