Pedestrian safety at signalized intersections operating the flashing yellow arrow

Creator:: Tuss, Halston
Abstract:: At signalized intersections, pedestrians are considered to be amongst the most vulnerable. When in the crosswalk at intersections without protected left-turn phasing, pedestrians are particularly at risk from left-turning vehicles. Until recently, a wide variety of indications were in use across the US to indicate a permissive left-turn condition to...

Driver Distraction from Unmanned Aerial Systems: Evidence, Policy, and Mitigation

Creator:: Barlow, Zachary W.
Abstract:: Unmanned aerial systems (UASs), more commonly known as drones, have recently achieved commercial success for many public and private applications. As with all emerging technologies, new safety concerns and conflicts with existing paradigms are likely to arise. Many potential applications of UASs will result in their operation near roadway infrastructure,...

Sound and Vibration Analysis of Alternative Rumble Strips

Creator:: Horne, Dylan Ross
Abstract:: Roadway departure crashes accounted for 18,275 fatal crashes in 2017 across the United States (Jones et al. 2017). Rumble strips (RS) provide audible and haptic interior alert when a vehicle is departing the roadway reducing run-off-the road crashes. Although inexpensive to install, and easy to maintain, RS are not installed...

Influence of Concrete and Construction Parameters on Chloride Test Measurements and Critical Chloride Threshold Limits

Creator:: Vaddey, Naga Pavan
Abstract:: The issue of chloride-induced corrosion of reinforcing steel in concrete and its economic impacts are well-known. Chlorides that cause reinforcement corrosion can be from constituent materials used to prepare concrete or can enter the hardened concrete when the structure is exposed to chloride environments. To minimize the risk of reinforcement...

Development of a Reliability-Based Framework and Empirical Models for Justifying Allowable Chloride Limits and Quantifying Critical Input Variables for Predicting the Service Life of Reinforced Concrete Structures

Creator:: Shakouri Hassanabadi, Mahmoud
Abstract:: Significant progress has been made over the past 20 years in developing models to estimate the service-life of reinforced concrete systems. The basic understandings of the mechanisms that control the transport of ions and moisture in concrete systems have been well researched and models for determining corrosion initiation, specifically chloride-induced...

Chemical transformation of rice husk ash for sustainable, constructable, and durable binary cementitious system

Creator:: Prasittisopin, Lapyote
Abstract:: The production of cement and concrete results in the production of large amounts of CO₂ emissions which can have significant negative environmental impacts. Using supplementary cementing materials (SCMs) as a cement replacement is an effective solution to reduce these negative environmental impacts, as most SCMs are waste by-products from other...

Assessing the seismic performance of corroding RC bridge columns

Creator:: Guo, Yisen
Abstract:: Corrosion of reinforcement is recognized as the predominant factor that limits the service life of reinforced concrete (RC) structures exposed to aggressive environments. This corrosion deterioration can lead to damage resulting in capacity loss or even failure. For structures exposed to coastal marine environments or deicing or anti-icing applications, this...

Development of a new mixture proportioning method and assessing the influence of material characteristics on flowing concrete mixtures

Creator:: Hendrix, Greg
Abstract:: Cast-in-drilled-hole (CIDH) piles are often constructed to depths that are inaccessible to internal vibration of the concrete. Internal vibration is necessary to consolidate the concrete and, if not performed, then typically inspection pipes are necessary to detect the presence of voids in CIDH piles. Void detection is critical to assessing...

Critical Assessment of Chloride States and Quantities in Ordinary Portland and Specialty Cements

Creator:: Ahmed, Ahmed Abdulhaq
Abstract:: The constituent materials of concrete often contain chlorides. The presence of chlorides in sufficient amounts can disrupt the passive layer, also known as the passive film, that protects the reinforcing steel in concrete. This disruption can lead to premature corrosion of the reinforcing steel in concrete. To minimize the risk...
