MPC Research Reports
Filter by Keyword26 report(s) found with air in the keywords field During area-wide episodes of poor air quality, people may reduce their transportation-related emissions by driving less, reducing their exposure to emissions by walking/bicycling less, or going about their lives as usual. These three reactions have different consequences for transportation, health, and... Recently, significant advances have been made in the development of rapid setting cementitious materials for partial-depth bridge deck repair. The rapid set times of these materials allow for traffic to be re-opened onto the bridge deck in several hours versus days once the material has been placed.... This report presents the relevancy of the allowable stress rating (ASR) and the load and resistance factor rating (LRFR) methods for timber bridges. Benchmark bridges constructed in the 1930s have been upgraded with hollow structural steel (HSS) beams and three-dimensional finite element models provide... U.S. residents across many regions continue to face episodes of poor air quality due in part to pollution and emissions from the transportation sector. Strategies to encourage travel behavior changes and reduced driving during such events may or may not be effective. To illuminate how area-wide air pollution... The research project produces a statewide airspace network, delivery schedule, and truck/drone fleet mix. Such an airspace network is optimized to ensure that drones are strategically deconflicted as required by NASA and the total energy over that day is minimized. Such an airspace network is realized... The first part of the study presents the time-dependent interfacial behavior of near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) strips bonded to a concrete substrate using inorganic resins. Four types of bonding agents (mortar, polyester-silica, ultra-high performance concrete (UHPC)... Airport operational data are necessary for aviation decision-makers to quantitatively prepare airport master plans and fairly distribute national funds throughout the country. These data have other important applications, such as safety and security applications. Interestingly, most airports (i.e., typically... The Rocky Mountain Region has experienced considerable difficulty because of alkali-silica reaction (ASR) in concrete construction. Wyoming Department of Transportation was successful in using recycled concrete aggregate (RCA) on Interstate I-80 with limited ASR damage. Reusing concrete from demolition... An evaluation of the ability of the BBR (Bending Beam Rheometer) as a test to determine changes in the low temperature properties of asphalt mixture parameters was conducted, along with the possible implications of adopting this test for low temperature pavement performance. It was found that the creep... This study is part of a multiple year study conducted at the University of Wyoming to assess the effectiveness of dust suppressant treatments on gravel roads. The multiple year study was conducted to assist the Wyoming Department of Transportation and the Federal Highway Administration optimize the use... |
