Evaluations of concrete mix stability for below-grade applications
(University of Missouri--Columbia, 2020)
and 42 inches tall. Each concrete mix was run through a series of quality assurance/control (QA/QC) tests to then compare to data collected while the test shafts were being cured, which includes the total volume of bleed water produced, the bleed water...
Function-based condition indexing for guyed communication towers
(University of Missouri--Columbia, 2005)
developed to organize the radio tower network via an internal (MoDOT server) site on the World Wide Web (WWW). DreamweaverR software is used to develop the website. The website contains the physical properties, tower drawings and some information regarding...
Investigation of smart work zone technologies using mixed simulator and field studies
(University of Missouri--Columbia, 2020)
Safety is the top concern in transportation, especially in work zones, as work zones deviate from regular driving environment and driver behavior is very different. In order to protect workers and create a safer work zone ...
Traffic impact assessment and mitigation strategies for disruptions
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation research focuses on modeling traffic conditions affected by disruptive events such as work zones, incidents, and hurricanes. Using a ...
Blast resistant forced entrty [sic] steel stud wall design
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Due to the threat of terrorist attacks, a series of tests has been conducted, on different forced entry wall configurations, to determine the static resistant function...
Static and creep response of RC beams strengthened with CFRP
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] The use of carbon fiber reinforced polymers (CFRP) for strengthening and retrofit of existing reinforced concrete members has been proven to be effective in improving...
Aquatic toxicity of one dimensional carbon nanomaterials
(University of Missouri--Columbia, 2010)
CNW) were selected to represent CNMs. Sediment tests were conducted for 10-d with SiCNW and for 14- and 28-d with CNTs using amphipods. Sonicated SiCNW in water were toxic to the amphipods but not to the midge, oligochaetes or mussels and non-sonicated Si...
Driving simulator use and calibration for work zone merge sign evaluation
(University of Missouri--Columbia, 2018)
complement traditional field work due to its feasibility, safety, and cost-effectiveness. In this thesis, a driving simulator was applied to model six scenarios, including three different types of merge signs: MUTCD (baseline), MoDOT, and Quebec. Each merge...
Automating traffic studies at modern roundabouts: a feasibility study
(University of Missouri--Columbia, 2007)
The modern roundabout is growing in popularity as an alternative intersection design, however it presents engineers a new quandary. At a traditional intersection, traffic movements may more easily counted given vehicle ...
Characterization of disinfection by-product precursors from Missouri streams
(University of Missouri--Columbia, 2007)
The NOM contained in drinking water sources reacts with Cl2 to generate THMs and HAAs. THMs and HAAs are regulated by EPA because they pose a health hazard. The nature of the DBP precursors is complex and not well understood. ...
Geotextile separators for dust suppression on gravel roads
(University of Missouri--Columbia, 2006)
Dust can be a health concern because of its potential to contain respirable particles. The US EPA and state environmental agencies developed and implemented a reporting system for the amount of particulate (PM10) derived from various sources...
