Filter by Keyword65 report(s) found with performance in the keywords field 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... 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. The North Dakota Department of Transportation (NDDOT) has installed two fixed automated spray technology (FAST) systems. One system is installed at the Interstate 29 (I-29) Buxton Bridge (near Buxton, ND), while the second installation is at the Interstate 94 (I-94) Red River Bridge between Fargo, ND... Recent studies have shown that the use of self-consolidating concrete (SCC) results in improved finished quality, increased production efficiency, and reduced labor cost. Because of the favorable properties that SCC exhibits, the Federal Highway Administration and the precast concrete industry have been... In this paper, rural and small urban transit agencies are classified into peer groups using hierarchical cluster analysis and data from the Rural National Transit Database (Rural NTD). The objective is to provide a basis for the comparison of individual agency to peer group performance as well as econometric... High Performance Steel (HPS) is a superior material with higher yield strength, improved weldability, greater levels of toughness, and improved weathering resistance that can lead to more economical bridges than conventional steel bridge designs. AASHTO Load and Resistance Factor Design (LRFD) provisions... In October 2005, the Federal Transit Administration and the Small Urban & Rural Transit Center at North Dakota State University held a meeting with several transit industry representatives launching a project to examine the state of small transit vehicles. The scope of this paper is primarily focused... |
