Filter by Keyword71 report(s) found with performance in the keywords field The initial statewide driver traffic safety survey provides baseline metrics for the Traffic Safety Office and others to use in understanding perceptions and behaviors related to focus issues. A core set of questions addresses nationally agreed upon priorities, including seat belts, impaired driving... Field samples were obtained from cores taken from multiple roads around the Salt Lake Valley in Utah and prepared for BBR testing. The response of field cores showed that even though the same binder grade used in the region was the same, the resulting mixtures have significant differences in creep moduli... The initial statewide driver traffic safety survey provides baseline metrics for the TSO and others in understanding perceptions and behaviors related to focus issues. A core set of questions addresses nationally agreed upon priorities, including seat belts, drinking and driving, and speeding. In addition... Depending on the location, highway bridges can often support considerable amounts of traffic. Due to the limitations on current earthquake forecasting techniques, a normal amount of traffic will also typically remain on a bridge when an earthquake occurs. In addition to traffic, scour effects are also... This study was precipitated by legislative action which mandated two transit coordination pilot projects in North Dakota. The report summarizes implementation efforts that were underway by the North Dakota Department of Transportation and presents recommendations and funding options concerning the continuation... This study was initiated to provide assistance to counties that were experiencing considerable impacts to their road systems from oil and gas drilling but were not receiving sufficient revenue to keep up with these impacts. As drilling expanded from Campbell County into Sheridan and Johnson counties... Current pavement design based on the AASHTO Design Guide uses an empirical approach from the results of the AASHO Road Test conducted in 1958. To address some of the limitations of the original design guide, AASHTO developed a new guide: Mechanistic Empirical Pavement Design Guide (MEPDG). This guide... The use of self-consolidating concrete (SCC) for the manufacture of precast structural elements provides the benefits of increased rate of production, reduced labor needs (safety), and enhanced product quality. The same benefits apply to cast-in-place construction, especially with closely spaced reinforcing... The objective of this report is to provide a benchmark for elevator managers in assessing performance, and supply a source for recognizing trends in the characteristics of North Dakota elevators. As more Recycled Asphalt Pavement (RAP) becomes available to use in roadways, The Wyoming T2/LTAP Center and two Wyoming Counties investigated the use of RAP in gravel roads. The Wyoming DOT and the Mountain-Plains Consortium funded this study. The investigation explored the use RAP as a means of dust... |
