Evaluation of a shoreline cleaner for enhanced removal of petroleum from a wetland
(Texas A&M University, 2000)
The impact and performance of a shoreline cleaning agent in the environment, Corexit®9580 (EC9580®), was evaluated by conducting a controlled release of weathered crude oil (Arabian-light) in May 1998 at a well characterized ...
Dynamic soil-structure interaction-comparison of FEM model with experimental results
(Texas A&M University, 2000)
Linearly elastic finite element models are developed for particular scale-model gravity retaining wall structures. The sand is modeled as a homogenous isotropic linearly elastic continuum. Models are created in four ...
The determination of thru-thickness residual bending stresses
(Texas A&M University, 2000)
In order to understand the fatigue behavior of dents in pressurized pipelines it is necessary to understand the residual stresses that result from cyclic plastic bending. Three approaches are taken here in studying a beam ...
Effects of aggregate gradation and angularity on VMA and rutting resistance
(Texas A&M University, 2000)
About 85 percent of hot mix asphalt (HMA) by volume and 95 percent of HMA by weight consists of mineral aggregate. The Strategic Highway Research Program (SHRP) research effort concentrated on properties and testing of ...
Evaluation of enhanced traffic control devices for use at highway-railroad grade crossings
(Texas A&M University, 2000)
A frequently cited factor in highway-railroad grade crossing accidents is driver error. Driver error may result from the failure to perceive a train at or near the crossing. Alternatively, drivers may detect train but fail ...
Development and validation of an areawide congestion index using Intelligent Transportation Systems data
(Texas A&M University, 2000)
The primary objective of this study was to examine potential areawide congestion indices using loop detector data, and to select one that best explains the congestion of a freeway system. Another objective was to determine ...
Predicting the behavior of nearshore feeder berms in the vicinity of Morro Bay, California
(Texas A&M University, 2000)
Being able to predict the final disposition of dredged material mounds is important in the planning of dredging operations. A computerized mathematical model, based on the sediment movement equations of Ackers and White, ...
An investigation of the information needs of air passengers traveling to the airport
(Texas A&M University, 2000)
According to the U.S. Department of Transportation, Bureau of Transportation Statistics, nearly 200 million person-trips over 100 miles one-way were taken by airplane in 1995, a 186 percent increase since 1977 (Bureau of ...
Effect of liquefaction on the behavior of a retrofitted pile foundation subjected to cyclic loading
(Texas A&M University, 2000)
Liquefaction is a major concern for bridge column foundations in earthquake prone regions. Although its effects are devastating to the structural integrity of foundations, there is little quantitative information to guide ...
Guidelines for storage distance between highway-highway and highway-railroad intersections
(Texas A&M University, 2000)
The issue of storage distance at highway-railroad grade crossings is one that has received a great deal of attention over the past few years. Several crashes involving buses and tractor-trailers have prompted the U.S. ...
