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...
Nondestructive Testing Role in Repair and Rehabilitation of Concrete Structures
Nondestructive testing (NDT) methods are increasingly being used to assess the condition of structural concrete. The paper discusses applications of NDT methods for forensic investigation...
Silica Fume Concrete: A Solution to Steel Reinforcement Corrosion in Concrete
This paper discusses the utilization of silica fume concrete admixture to prevent reinforcing steel corrosion. The mechanism of steel corrosion in salt impregnated concrete is described,...
Application of Radar Imaging Techniques to Concrete
Wideband radar imaging techniques have the potential of being a powerful tool in detecting steel reinforcing bars and delaminations inside concrete. The success of the method as a nondestructive...
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....
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...
Airfield Pavement Structural Evaluations, Current Practice and Future Needs
The United States Air Force's pavement evaluation teams have to be able to go quickly anywhere in the world to evaluate an airfield pavement's structural capability. A combination of non-destructive...
A Novel Approach to Develop a Performance Based Test for Rutting of Asphalt Concrete
Asphalt concrete consists of compacted granular aggregates mixed with viscoelastic asphalt cement. The predictive phenomenological models had limited success in explaining the origin and...
Portland Cement Concrete Apron Pavement Design Study for King Fahd International Airport in Saudi Arabia
The Federal Aviation Administration (FAA) Advisory Circular 150/5320-6C used for design of portland cement concrete (PCC) pavements for airports does not account for the site-specific...
Evaluation of Elastic Layered Theory for Airfield Pavements, Using Nondestructive Testing and In-Place Response Measurements
Airfield pavement deflections measured under actual aircraft loads were compared to predictions based upon elastic layer theory and moduli backcalculated from failing weight deflectometer...
Quality Control: Bridge Steel Fabrication and Erection
This paper examines the Quality Control Program Plan (QCPP) developed by Frederic R. Harris, Inc. (FRH) for fabrication and erection inspection of over 5,448,000 kg of AASHTO Fracture...
Pin Piles Save Silos
The United Grain Corp. annually ships about 200 million bushels of wheat and other grains to destinations around the world from its leased facility on the Columbia River at Vancouver,...
In Search of Better Load Ratings
Typically, engineers must make a number of subjective assumptions regarding loading and response behavior when they develop a load rating for civil structures. As a result, many unknowns...
Haunted by the Past
Given the legacy of the construction of the Missouri Valley Water Tunnel in the 1920s�eight deaths and numerous injuries�it's no wonder that safety was foremost in the minds...
Seismic Design of Multi-Story, Wood-Framed Buildings
The seismic design and analysis of wood-framed structures is relatively simple; however, the challenges that present themselves within this design medium are shear and overturning force...
Stabilization of South Texas Soils with Fly Ash
The expansive soils of south Texas have traditionally been stabilized with lime or Portland cement. As an alternative, a class F fly ash was tried to stabilize expansive soils obtained...
Enzyme Enhanced Stabilization of Soil and Fly Ash
The purpose of this research was to determine if enzymes could be utilized to increased the strength and stability of soil mixed with fly ash. Samples were prepared with and without the...
A Study of Engineering Properties of a Clay Modified by Ash and Slag
Fly ash from power plants and slag from steel mills are two industrial solid wastes. These wastes can be utilized as soil stabilizers. In this study, a clay with low plasticity is mixed...
Driven Then Pushed Minicone Tests in a Sand Chamber
For a general knowledge on the Standard Cone Penetrometer test and its uses the reader is referred to the work of Briaud and Miran (1991). For this study (Khalaf and Briaud, 1992) a smaller...
Lateral Loading Curves from Pressuremeter Tests
The large drilled shafts for the proposed Klamath Falls Bridge, which are to be founded in diatomaceous silts, were to be designed to withstand earthquake induced large cyclic loading....
