Development of design criteria pertaining to signing, pavement markings, and geometric cross-section for improved two-lane section (Texas Super 2)
(Texas A&M University, 2001)
The purpose of this research was to establish the optimum driver information strategy regarding Super 2 passing lane sections in Texas. A Driver Survey and a Before and After Study examining proposed skip stripe pavement ...
Laboratory measurements of the temporal and cross-shore variation of the wave-induced bed stress
(Texas A&M University, 2000)
Detailed laboratory measurements of horizontal velocity above a rough, fixed, impermeable slope were made to determine the effect of varying wave conditions on the shear stress in the swash zone. The research involved the ...
A decision process framework: selecting strategies for rehabilitation of rigid pavements subjected to high traffic volumes
(Texas A&M University, 2000)
Concrete pavements, underdesigned for today's levels of traffic, are deteriorating rapidly. Maintenance, rehabilitation, and reconstruction activities (MRR) have become more widespread and costly. State highway agencies ...
Cracking in reinforced concrete bent caps
(Texas A&M University, 2000)
The objective of this research program was to determine the causes of cracking in the cantilever portion of multi-column reinforced concrete bent caps that exist within the Texas Department of Transportation bridge inventory. ...
Development of statistical wet weather model to evaluate frictional properties at the pavement-tire interface on hot mix asphalt concrete
(Texas A&M University, 2001)
Skid resistance on wet pavements is influenced by friction at the tire-pavement interface as well as overall hot mix asphalt (HMA) performance. It is important to control aggregate, asphalt, and mix properties to achieve ...
Optimizing detector placement for isolated intersections based on minimizing average delay and number of stops
(Texas A&M University, 2000)
Detector layout has a significant effect on the performance of an intersection. Operational performance of an intersection is often measured with delay. Delays experienced in rural areas are not significant due to low ...
Visual complexity in highway work zones: an exploratory study
(Texas A&M University, 2002)
Work zone safety is a priority of the transportation profession. One way to increase work zone safety is to identify the situations that threaten safety. This study was completed as an exploratory analysis of possible ...
Development of a neural network model to nowcast/forecast the coastal water level anomalies on the entrance to Galveston Bay, Texas
(Texas A&M University, 2002)
The water level anomaly, or the difference between the observed water level and that predicted by harmonic analysis (meteorological tide), was studied in this thesis for two locations on the northwestern Gulf of Mexico. ...
A comparison of fracture properties of selected geosynthetic products using pseudo strain damage theory
(Texas A&M University, 2001)
Reflective cracking is one of the more serious distresses associated with existing hot mix asphalt (HMA) or portland concrete cement (PCC) pavements overlaid with a thin bituminous layer. This phenomenon is commonly defined ...
Construction project delay-analysis techniques
(Texas A&M University, 2002)
The construction industry is considered one of the largest money-generating industries of the economy. Construction time is a highly critical aspect for all parties involved in a project. However, delays in construction ...
