Ultrasonic thickness testing of aging offshore structures
(Texas A&M University, 1999)
The objectives of this thesis concern the use of ultrasonic thickness (UT) testing for use in the offshore industry. Evidence from prior studies conducted at Texas A&M University suggests that the corrosion on the surface ...
A laboratory study comparing the effectiveness of three dust palliatives on unpaved roads
(Texas A&M University, 1999)
Three different aggregate types were each treated by three commercially available dust palliatives and tested in the laboratory to quantify their resistance to erosion by wind and traffic. An untreated control specimen was ...
Comparison of vehicle travel times and measurement techniques along the I-35 corridor in San Antonio, Texas
(Texas A&M University, 1999)
The floating car method of travel time data collection has been used since the 1920's to evaluate transportation issues such as congestion management and freeway operation. However, this technique can be time consuming, ...
Legibility of freeway Lane Control Signals
(Texas A&M University, 1994)
This thesis documents the results of a laboratory study designed to evaluate and compare the glance legibility distance of commercially available freeway Lane Control Signals (LCS). Two prototype fiber-optic lane control ...
Accident causation study on roadways with limited sight distance crest vertical curves
(Texas A&M University, 1994)
Stopping sight distance is an important parameter used in the design of a roadway's horizontal and vertical alignment. Many of the parameters used in the current stopping sight distance equation were developed in the 1950s ...
A quality management approach to civil engineering
(Texas A&M University, 1999)
A methodology is presented for basing quality improvement decisions in civil engineering design firms upon historical data, statistical methods, and hydrologic modeling techniques. Statistical Process Control (SPC) is a ...
Fatigue behavior of full-size soild-sawn timber railroad stringers
(Texas A&M University, 1999)
As part of the Timber Bridge Life Extension Program sponsored by the Association of American Railroads (AAR), the objective of this thesis is to investigate the fatigue behavior of large solid-sawn timber beams. Specifically, ...
Qualification of concrete mixtures for fast track construction applications
(Texas A&M University, 1997)
Fast track construction is a special type of construction where construction methods and activities are planned to minimize the construction duration. Since the duration of the hardening period of concrete is largely ...
Ultrasonic thickness measurements on corroded steel members: a statistical analysis of error
(Texas A&M University, 1999)
The purpose is to determine the suitability of ultrasonic thickness testing of corroded tubular members for the offshore industry. The research can be divided into two parts: 1) determining the error in an ultrasonic ...
Evaluation of an alternative bituminous material as a soil stabilizer
(Texas A&M University, 1999)
Asphalt cements, cutback asphalts, and emulsified asphalts are used as bituminous stabilizing agents in the pavement systems. The emulsified asphalts are increasingly used in lieu of cutback asphalts because of environmental ...
