MPC Research Reports
View AllIn 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 study addresses the issue of retrofitting reinforced concrete column/cap joints with advanced carbon-fiber composites using full-scale laboratory specimens. This study compares the performance of left-turn phasing to provide quantifiable benefits of one phasing over another. From the analysis, guidelines are developed for determining the type of left-turn phasing based on left-turn volume, opposing through volume and lane geometry. The objective of this research is to develop a computer-based delivery system for one of Utah DOT's existing, traditional classroom training activities. The Flagging Recertification Training and Exam was selected by the UDOT Technical Advisory Committee. The research was divided into two phases: (1)... A variety of computer tools are being used by UDOT to serve diverse maintenance management needs. Many of the tools are individually tailored for a specific purpose and lack the functionality to share data with other applications. This has resulted in the establishment of numerous databases which are... The Utah Department of Transportation (UDOT) recently investigated the cost and effectiveness of entry-level video conferencing systems (see MPC Report No. 96-67). The systems were required to run on a Pentium 60 MHz computer with 8 mb of RAM which was connected to the Internet. The Computer Based Intelligent... This report presents the results from expert interviews with Minneapolis-St. Paul companies and North Dakota manufacturing companies. The Minneapolis expert interviews helped to identify the minimal logistical capabilities a supplier must have in order to do business with the Minneapolis companies. Ten... This research developed a methodology to optimize roadway access intersection design using an expert system to guide design in accordance with published criteria, a graphical multi-criteria evaluation system, which revealed marginal impacts of changing design parameters across three objective functions... The results of this project demonstrate the need for functional sub-classifications of rural local roads, with design parameters that address the unique characteristics of these roads. Incremental improvements are an acceptable method to increase safety on unpaved rural roads and to minimize liability. The principal investigators addressed many aspects of distance learning in a recently taught TEL8 course on bridge engineering. Their efforts are outlined in this report with respect to this course. The fruit of their effort is a better and more technologically advanced method of coupling TEL8 courses... |
