MPC Research Reports
Filter by Author59 report(s) found for Khaled Ksaibati Current pavement design methodology based on the AASHTO Design Guide uses an empirical approach based on the results of the AASHTO Road Test conducted in 1958. But limitations of the current guide led AAHSTO to publish the new Mechanistic Empirical Pavement Design Guide (MEPDG), which combines mechanistic... SAFETEA-LU contains language indicating that state department of transportation (DOTs) will be required to address safety on local and rural roads. It is important for state, county, and city officials to cooperate in producing a comprehensive safety plan to improve their statewide safety. This legislation... This report details the results of a project aimed at determining how to legally establish a county road in Wyoming. This report covers the laws on this issue from territory days until the present. It consists of a survey, case law, statutory law, federal law, direction and a final desk reference. The... The utilization of recycled glass in highway applications has been occurring over the past couple of decades. In recent years, the discovery of several economic and environmental benefits could increase the use of recycled glass in highway construction, making the evaluation of the engineering properties... This report is Phase II of a previous MPC research project (MPC 02-136) that developed a computer model using a transient, two-dimensional finite volume approach to mathematically describe the thermal response of asphalt pavements due to thermal environmental conditions on an hourly basis. The main objective... 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 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... |
