Filter by Keyword8 report(s) found with rutting in the keywords field 1 - 8 of 8 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... 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. This project used field and laboratory evaluations to study the possibility of incorporating bottom ash in asphalt mixes. A pavement test section was constructed for the field portion of the project. The laboratory evaluations involved design and accelerated testing of control and bottom ash asphalt... In this study, the researchers evaluated the performance of asphalt mixes prepared using the Marshall mix design method and the Superpave level one mix design method. The Georgia Loaded Wheel Tester and the Thermal Stress Restrained Specimen Tester were used to test the rut-resistance and low-temperature... The feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated in this research. This research was performed in two phases. The first phase consisted of modifying the GLWT to handle 15.2 cm (6 in) cores, developing a laboratory compaction procedure... In this research the feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated. The study consisted of modifying the GLWT to handle 15.2 cm (6-in.) cores, obtaining asphalt pavement cores from several test sites throughout Wyoming, collecting rut... This report describes a study conducted at the University of Wyoming to evaluate the various factors affecting the accuracy of Road Profilers measurements. Highway agencies across the U.S. use Road Profilers to measure roughness and rut-depth characteristics of pavements. These measurements are utilized... |
