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...

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...

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...

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....

Image Analysis of Clay Microstructure
The paper summarises new methods which have been developed to analyse oriented textures in electron micrographs of clay soils, complementary methods using polarising microscopy, and an...

A Chemical Image Analysis Procedure as a Method for a Quantitative Modal Analysis of Clinker Minerals
In a chemical image analysis procedure, the specimen is analyzed in a scanning electron microscope in backscatter mode, thus providing an atomic number contrast. The phases are segmented...

Radiographic Visualization in Experimental Soil Mechanics
A summary of the principles of such methods is presented, i.e. stereophotogrammetry, infrared thermography and radiography and their respective ranges of applicability are discussed. Then,...

Interactive Digital Image Feature Analysis as Applied to Cement and Concrete Microstructural Investigations
A novel procedure involves interactive chemical image analysis of separable features in the backscattered image. In this procedure a backscatter image is acquired by the image analysis...

Digital Image Techniques for Volume Change Measurements in Triaxial Tests
This paper presents an innovative technique that has been used for measuring the volumetric deformation that cylindrical specimens experience during the shearing stages of a triaxial test....

Image Analysis for Interparticle Contact Modeling
Two dimensional photoelastic elements (disks or ellipses) are used as models for studying granular material behavior. The required observations include accurate continuous measurements...

Displacements in the Soil Near a Tunnel Face Using Centrifuge Tests and Image Processing
Image processing is applied to measurements of the soil for a tunnel model in centrifuge. For this aim a specifical device has been developed on the LCPC centrifuge (Nantes, France) and...

Image Analysis Applied to Geotechnical Engineering
Application of scanning electron microscope and image analyzer to the quantification of grain morphology and microfabric of aged sands is briefly reviewed. Relationships of morphology...

Mechanistic Design Models of Loading and Curling in Concrete Pavements
Determination of the critical bending stress at the edge of a concrete pavement due to individual and combination effects of wheel loading and thermal curling is very crucial to any mechanistic...

Finite Element Analysis of Slabs-on-Grade Using Higher Order Subgrade Soil Models
Incorporation of the two-parameter, Kerr and Zhemochkin-Sinitsyn-Shtaerman subgrade models into finite element code ILLI-SLAB is described. The two conventional idealizations, namely the...

Mathematical Modeling of Airport Pavements
Theories for analyzing rigid pavements are presented. The emphasis is on the choice of the proper models for the pavement and for the subgrade, and on the correct mathematical formulation...
