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 ...
The evaluation of Cooper ratings for in-service timber railroad bridge stringers independent of the timber specie
(Texas A&M University, 2003)
The objective of this thesis is to determine a method for assigning a rating to in-service timber railroad bridges. The standard method of rating a railroad bridge is to assign a Cooper E rating which corresponds to the ...
An experimental investigation of mine burial penetration in soft sediments
(Texas A&M University, 2003)
An experimental program was conducted to study the penetration behavior of mines in soft sediment. Model tests were conducted on sediments collected from the Gulf of Mexico seabed. The size of the model mine was approximately ...
Quantify shape, angularity and surface texture of aggregates using image analysis and study their effect on performance
(Texas A&M University, 2003)
There is a consensus among researchers that the aggregate shape properties affect performance, but a debate has risen over the suitability of these physical tests to quantify the related shape property. Most of these ...
Performance based evaluation of the seismic resistance of structures with concrete diaphragms
(Texas A&M University, 2001)
Under seismic loading, floor and roof systems in reinforced concrete (RC) buildings act as diaphragms to transfer earthquake loads to the vertical lateral force resisting system (LFRS). In current practice, horizontal ...
Stiffness-Mass Ratios Method for a baseline determination and damage assessment of a benchmark structure
(Texas A&M University, 2002)
A new method based on ratios between stiffness and mass values from the eigenvalue problem is introduced and applied to the benchmark structure to obtain baseline modal parameters utilizing damaged state information of the ...
Use of neural networks to correlate enzymatic hydrolysis with biomass properties
(Texas A&M University, 2001)
A neural network was used to correlate enzymatic digestibility with the following biomass properties: lignin content, acetyl content, and crystallinity index (CrI). The neural network model was not able to improve a ...
Factors affecting binder properties between production and construction and their impact on quality assurance programs
(Texas A&M University, 2002)
The majority of the US Departments of Transportation (DOT) require as part of their quality assurance (QA) programs that the asphalt binder used during roadway construction meet the corresponding Superpave performance grade ...
Identification of research and development needs in highway construction engineering and management
(Texas A&M University, 2001)
Ten years have passed since the last assessment of research and development needs in highway construction engineering and management (CEM) and a new research program is necessary to indicate the direction and focus of ...
Evaluation of mechanical properties of high strength concrete for prestressed concrete bridge design
(Texas A&M University, 2001)
High strength concrete (HSC) are widely used in prestressed concrete bridges in Texas. However, current design provisions for prestressed concrete bridge structures such as the AASHTO LRFD Specifications (2000) were ...
