MPC Research Reports
Filter by University100 report(s) found for University of Utah Transportation asset management requires timely information collection to inform relevant maintenance practices. Traditional data collection methods often necessitate manual operation or the use of specialized equipment, e.g., light detection and ranging (LiDAR), which can be labor-intensive and costly... In several states, bridge deck delamination of reinforced concrete bridge decks built with partial depth precast concrete panels and cast-in-place concrete has been observed. The partial depth precast concrete panels are typically prestressed. Recently, one such failure was observed in Utah. There is... A numerical model simulating the seismic behavior of precast concrete columns confined with glass fiber reinforced polymer (GFRP) spirals and longitudinally reinforced with steel or a combination of steel and GFRP bars was developed using the Open System for Earthquake Engineering Simulation (OpenSees).... This report documents the effort to develop a practical relation between the cracking tolerance index and portions of the dynamic modulus curves of asphalt mixtures. A review of practices used to create asphalt mixtures' dynamic modulus master curves, based on NCHRP reports and other relevant literature... 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... Fiber reinforced polymer (FRP) composite materials have been studied and applied to reinforced concrete (RC) structures for strengthening or seismic retrofit for many years. This research is related to using FRP composites in new bridge structures. Capacity degradation in RC components of existing bridges... Roadside safety is a critical aspect of transportation management, with elements like rigid obstacles, guardrails, clear zones, and side slopes significantly impacting accident outcomes. The Federal Highway Administration (FHWA) provides a valuable rating system for departments of transportation (DOTs)... Understanding ramp queue length and queuing time is important for transportation agencies to manage and operate the ramps with optimum performance. Since these data are collected with conventional sensor systems such as coils, they are prone to error, especially during traffic congestion. The increased... The purpose of this research project was to investigate and determine the reasons for premature deterioration of the geogrid-reinforced pavement system on the section of SR-10 between Muddy Creek and Emery, Utah.
The statistical analyses and evaluations indicate that the structural design of the primary... The U.S. Department of Transportation (USDOT) needs to respond quickly and adapt to the coronavirus (COVID-19) to ensure continuation of critical infrastructure support and relief for the American people. Since early March 2020, the COVID-19 pandemic has had significant impact on traffic across the United... |
