The analysis assesses the freeway operations before the HOV lanes opened with continued assessment throughout the first year of operation. It looks at automatic data from traffic monitoring stations and manual data from roadside... A survey of the education and training needs was conducted and more than 2,000 questionnaire booklets were sent to highway contractors nationwide. Two hundred and eighteen responded. The objective of the survey was to determine the training and education needs of the construction industry and identify... President Joseph A. Chapman has charged North Dakota State University to move to the next "level of excellence" in its service to North Dakota. The Upper Great Plains Transportation Institute is a full partner in that desired growth and progress. The Institute's continuing research, education, and service... 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... This report is a summary of the impressions, as well as the recommendations, drawn by Gene Griffin, director of the Upper Great Plains Transportation Institute, NDSU; and Dennis McLeod, president, Red River Valley & Western Railroad. These impressions and recommendations are based on an eight-day site... This report presents a brief historical overview of the development of expansive (shrinkage compensating) concrete. Three Utah Department of Transportation projects using expansive concrete are discussed as to the performance of the expansive concrete. On-site inspections were performed on three projects... The involvement of the Center for Urban and Regional Affairs (CURA) in transportation research on Indian reservations began in 1989 when CURA received a small grant from the University of Minnesota's Center for Transportation Studies.

Critical issues in managing computing resources in a design operation are staffing, maintaining, and financing a highly dynamic system. Managing such a system properly... The primary objective of this study was to investigate the effects of freeze-thaw conditioning and overloading on the resilient modulus (Mr) of subgrade soils susceptible to frost penetration. The Mr values of conditioned samples were compared to unconditioned samples. All Mr values were determined in... |
