Database for Pipeline Bridges in North America
Work began in 1985 at Wayne State University on a research study of pipeline suspension bridges. This effort, which was funded by ANR Pipeline Company of Detroit, Michigan, investigated...
The Load Factor
Spangler's load-factor formula for projecting conduits is generalized to all cases of buried rigid pipe, whether in trenches or under embankments; this is in accordance with the analytical...
Chemical Resistance of Thermosetting Resins Used for Cured-in-Place Pipe
This paper summarizes the chemistry, short term physical properties, and long term chemical resistance for representative epoxy vinyl ester, epoxy, and polyester resins that are currently...
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,...
Accessibility of Geotechnical Earthquake Engineering Data and the Need for Data Storage and Dissemination Standards
Ease of data access and data standards are two issues critical to the success of GIS technology when applied to earthquake hazards research problems that require geotechnical engineering...
Steel Exoskeleton Defines Architecture
The Hotel de las Artes multi-use complex in Barcelona, Spain consists of a luxury hotel/apartment tower, a commercial office building, retail, parking and other amenities. The most prominent...
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...
ICAO's ACN-PCN Method and Aircraft-Pavement Interaction
Multi-wheel gear assemblies of future aircraft are not compatible with pavements rated in the ACN-PCN system given by the International Civil Aviation Organization (ICAO). The Aircraft...
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...
Resin Modified Pavement in Airfield Applications
The resin modified pavement (RMP) is a composite paving material that combines the flexible characteristics of an asphalt concrete (AC) material with the durability of a portland cement...
Evaluation of a Large Aggregate Asphaltic Layer in an Airside Pavement
A new analytical method of designing large aggregate asphalt mixes (LAM) was used to design a thick asphalt base layer for an aircraft taxiway. The results of an analysis on the material...
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...
Measurement and Analysis of Airside Pavement Roughness at the Dallas/Fort Worth International Airport
In May 1990, Dallas/Fort Worth International Airport management contracted with Harding Lawson Associates to implement a pavement management system for that airport. In this implementation,...
Honolulu International Airport (HIA) APM
The Hawaii Department of Transportation, in planning to meet passenger demands over the next 20 years, is providing for expanded terminal buildings. The expanse of the airport requires...
Drilling with Direction
Norfolk, Va.'s 48 in. diameter raw water main crosses three rivers in its 52,000 ft route. At the Elizabeth River, an aerial or subaqueous crossing was not feasible, so a...
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...
All Dressed Up
Its location at 660 Madison Avenue will put the new home of clothier Barneys New York in the heart of Manhattan's exclusive midtown shopping district, but the $120 million...
Dynamic Loading
This chapter deals with those problems of finite element analysis of concrete structures, which arise from the dynamic nature of loadings. Following a short enumeration of the dynamic...
LRFD for Timber Structures
The use of load and resistance design (LRFD) methodologies is increasingly becoming the standard analysis procedure for engineering design. The concrete industry has used a variation of...
