Development of an electrical resistivity cone for the detection of gas hydrates in marine sediments
(Texas A&M University, 1994)
Natural gas hydrates are formed when, under certain pressure and temperature conditions, gas molecules become encaged by hydrogenbonded oxygen atoms, forming a solid, ice-like crystalline substance. They have been found ...
A framework for a coarse aggregate classification system
(Texas A&M University, 1994)
Coarse aggregates are the major constituents of concrete or asphalt mixtures and are widely used in various construction purposes. A classification system for these aggregates would provide a systematic means of aggregate ...
An evaluation of pavement markings and raised pavement markers at left exit lane drops
(Texas A&M University, 1994)
Most highway engineers agree that freeway exit lane drops create problems in terms of safety and efficiency. A driver can create a hazardous situation when making a sudden lane change out of or into an exit-only lane. Since ...
Effects of superpave aggregate gradation on permanent deformation
(Texas A&M University, 1999)
In order to improve the performance, durability, and safety of United States roads, the Strategic Highway Research Program (SHRP) was established by Congress in 1987 as a five year research program. SUPERPAVE[] (Superior ...
Study of an interconnected flashing warning light system for work zone lane closures
(Texas A&M University, 1999)
A prototype work zone interconnected flashing warning hics. light system was tested in this thesis research that was conducted in coordination with an ongoing research project by the Texas Transportation Institute (TT1) ...
Tests of concrete beams with externally-bonded glass-fiber fabric web reinforcement
(Texas A&M University, 1999)
Reinforced concrete structures deteriorate with use and over a period of time, due to several factors such as physical and chemical aging, corrosion, service loads exceeding design loads and inadequate durability. One of ...
A theoretical study of discrete air phase migration contaminated with a volatile organic
(Texas A&M University, 1997)
A theoretical study of discrete air phase migration contaminated with a volatile organic is developed in order to study air bubble migration through granular porous media in air sparging technology. The experiment is ...
Emerging technologies and their application in construction engineering
(Texas A&M University, 1999)
This thesis presents the potential applications and benefits that construction engineering could achieve through the implementation of information management technologies. Regarding construction engineering, the area of ...
Verification of the performance of the Multi-Piezometer Array System for the measurement of pore pressures in shallow marine sediments
(Texas A&M University, 1999)
The Multi-Piezometer Array System (MPAS) was constructed and delivered for use to Texas A&M University in the fall of 1996. The MPAS is a highly sophisticated measurement system designed to measure changes in in situ pore ...
Modeling fatique behavior of dents in petroleum pipelines
(Texas A&M University, 1997)
Dents in pipelines can seriously reduce the design life of a pipeline. Dents cause stress concentrations to develop which make dents susceptible to fatigue failures. Acceptance criteria of dents are currently only based ...
