This research investigates moisture susceptibility of asphalt mixes; evaluates the effect of various numbers of freeze-thaw cycles on the mechanical properties of asphalt and determines if the Georgia Loaded Wheel Tester can be used to test for moisture induced damage.
Fluctuation in temperatures significantly affects pavement stability and the selection of asphalt grading to be used in pavements. Ability to accurately predict the asphalt pavement temperature at different depths and horizontal locations based on ambient air temperatures will greatly help pavement engineers...
This research examines a range of incident detection technologies to determine a recommended combination of approaches for use in the Utah Department of Transportation (UDOT) Advanced Traffic Management System (ATMS). The technologies that were examined are computer-based Automatic Incident Detection...
This report contains a brief description of Intelligent Transportation Systems (ITS) and ITS technologies for Commercial Vehicle Operations (ITS/CVO). Second, it discusses previous literature regarding benefits of ITS/CVO for motor carriers, as well as managing the change due to technology. In addition...
Six major railroads provided the Transportation Technology Center Inc. (TTCI) with defective rail that had been removed from service. The rail, which contained a variety of defects, was placed into a gauntlet track at the Transportation Technology Center (TTC). This paper is the assessment of those six...
This report examines the feasibility of using the thermal stress restrained specimen test to evaluate low temperature cracking in asphalt pavement mixes. Data were collected from laboratory and field evaluations. Various mixing, aging, and compaction methods were used to prepare test samples with materials...
The objectives of this research are to determine how regional trucking firms are incorporating logistical services into their business, show some of the current trends regarding logistics in the trucking business, and allow firms to evaluate themselves against the rest of the industry.
Manuals of instruction are important engineering tools because they provide the necessary information to perform important design procedures and calculations correctly and accurately. The objective of this project was to develop a computer-based manual of instruction by implementing tools and techniques...
