Evaluation of superpave fine aggregate specification
(Texas A&M University, 1999)
Superpave[] was the final product of the Strategic Highway Research Program's (SHRP) asphalt pavement research effort during 1987-93. Some aspects of the Superpave aggregate specifications are not universally accepted. The ...
The impact of maintenance and rehabilitation strategies on the pavement network value
(Texas A&M University, 1999)
The maintenance and rehabilitation of road infrastructure demands a great investment of time and money. The deterioration of pavement condition over time due to environmental factors and increasing traffic loads combined ...
Seismic structural response from continuous and discrete models
(Texas A&M University, 1999)
The Northridge Earthquake of 1994 caused unexpected cracking in the connections of Steel Moment-Resisting Frame (SMRF) buildings. This thesis investigates the possibility that higher-than-expected strain rates in the ...
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, ...
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, ...
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 ...
