MPC Research Reports Filter by Keyword66 report(s) found with roads in the keywords field This project has investigated the performance of the admixtures during and after leaching has occurred. This report presents information in two main areas of investigation. The first is a soil column study to determine downward, one-dimensional solute transport properties and trends of the admixtures... The purpose of this study is to encourage competition among rail carriers by facilitating communications between North Dakota elevators and their rail carriers regarding customer service issues. By conveying marketing and customer service information for the four railroads, the competition for business... This document is the second in a series of three manuals produced for the South Dakota Department of Transportation. It is intended for use by county superintendents and other county roadway agency personnel within the State of South Dakota for the efficient selection of maintenance, rehabilitation... Rural Road Management Guide (Sep 1995, MPC-SD95-16-G3) This Guide contains information about the management of paved and gravel roads. The approaches to managing paved versus gravel roads differ in some respects. Both include an inventory of the physical characteristics of the road network and an assessment of the road condition; however, the analysis of... This Guide has been developed to help provide a consistent means of assessing rural roadway conditions, both within a county and statewide. The roadway evaluation methodology described in this Guide will provide county highway agencies with a uniform and consistent means of defining pavement and roadway... This report describes a research project conducted at Colorado State University to evaluate the relative effectiveness and environmental impact of road dust suppressants. The objectives were to develop a device that would provide a standard, quantitative and precise method of measuring dust from unpaved... Since 1980, over 200 new local or regional railroads have been established in the United States, mostly through the sale of light-density lines by Class I carriers. With these new additions, this sector of the railroad industry now numbers over 400 strong. Collectively, these firms operate over 40,000... This paper presents results of laboratory tests conducted to determine the effects of additives on the stabilization of unpaved road surfaces. Laboratory tests can be an efficient means of determining which additive will best stabilize a given unpaved road surface, but correlation between laboratory... This paper examines the effectiveness of applying chip seal friction courses in reducing accidents on low volume, rural roads. Chip sealing data from District 3 of the Utah Department of Transportation were used to examine accident rates before and after applying chip seal. Although accident rates generally... The overall purpose of this report is to evaluate the perspectives and practice of economic and safety regulation of local and regional short line railroads. Specific objectives are to: (1) review the dynamics of the short line railroad spin-off movement in the United States and the Mountain-Plains Consortium...
