Filter by University113 report(s) found for University of Wyoming This research evaluates the effectiveness of hot-poured crack surfacing material and its ability to seal asphaltic cracks. The term "crack surfacing" is used to describe the rigidity of the material and to distinguish it from crack sealants. The University of Wyoming, in cooperation with the Wyoming... Coal ash is the portion of ash rejected by the stack and collected at the base as a waste product. Coal ash is comprised of bottom ash and fly ash. Fly ash accounts for 70 percent to 80 percent of total coal ash and the rest being bottom ash. Only 39 percent of bottom ash is utilized with the rest being... The movement of freight within the state of Wyoming is very critical to Wyoming's economy as well as the national economy. Wyoming's transportation system provides a vital link for the movement of commodities across the United States, in addition to providing access to the mineral, industrial, and agricultural... The main objective of this research was to quantify the differences and similarities among Quality Control/ Quality Assurance (QC/QA) programs for three state highway agencies. By measuring these differences, conclusions were drawn as to which state was achieving the best results with their QC/QA program.... The main objective of this study was to investigate the effect of the addition of a coal combustion remnant called bottom ash into asphalt mixes. The intent was to determine if mixes prepared with bottom ash showed degradation of desirable performance measures when compared to control mixes. This was... In this study, the researchers evaluated the effectiveness of quality control/quality assurance (QC/QA) specifications in decreasing hot mix asphalt (HMA) variability. A questionnaire was written to gather general information about the QC/QA specification programs that are being used in the United States... 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... State Highway Agencies (SHAs) in the United States use smoothness specifications to insure that they are providing the public with quality roads. Monetary incentives / disincentive policies based on the initial roughness values are used by SHAs to encourage contractors to build smoother roads. To justify... This report presents results of an investigation into the practice and legal issues of Road Safety Audits and Road Safety Audit Reviews (RSAs and RSARs). These safety analysis approaches focus on identifying safety issues of proposed projects (RSA) and existing roadways (RSAR). In the United States... |
