Filter by Keyword8 report(s) found with guides to the literature in the keywords field 1 - 8 of 8 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... When transportation agencies become involved in the remediation of hazardous waste on their sites, the common practice is to hire consultants and contractors for the clean up process. Because the field of hazardous waste site remediation is changing so rapidly, agency personnel evaluate the consultant's... This project included two laboratory studies and analytical work dealing with T-beams comprised of a concrete flange connected to a wood beam plus plywood sheathing. Based on the experimental results of tests of 72 slip specimens and 4 full-scale layered T-beams, the mechanical behavior of different... The objective of this project is to provide local transportation officials with the information required to make sound decisions on the management of the bridges within their jurisdiction. Automated procedures were developed to prioritize the required maintenance, rehabilitation, or replacement (MR&R)... The primary purpose of this study is to develop a research agenda which provides solutions to the problems experienced by rural transit operations in the Mountain-Plains Region. In order to achieve this, the specific objectives of this study are to: (1) examine factors that make rural transit unique... Communication of current road and travel conditions may potentially reduce the number of accidents attributable to wintertime driving in rural mountain states. This research paper addresses the provision of current road and travel information to road users. There is a potential for using real-time remote... Economic development efforts are addressed as "family of services" to prospective businesses. There is some uncertainty if transportation/logistics should be considered as a factor within the family of services. The overall goal of this study was to develop a better understanding of the relationship... The overall objective was to determine the extent that economies of size and density are available to short line railroads. Size economies are limited for short line railroads. For example, doubling the size of the network (from 56 to 129 miles) decreases costs by only 6.9 percent. The elasticity of... |
