Driving simulation : a mechanism for understanding driver response to mobile barriers in work zones

Creator:: Swake, Joshua
Abstract:: Highway construction projects require temporary changes in roadway characteristics, such as the number of operational lanes, lane path, lane width, shoulder width, and posted speed limit. These modifications which are often temporary in nature have the potential to impact driving performance. Many research efforts have focused on developing standards to...

The Effects of Construction Practices on Concrete Construction Joint Performance

Creator:: Panduranga Setty, Shreyas
Abstract:: Concrete is the most widely used construction material in the world. When constructing large concrete structures, concrete may have to be placed in multiple lifts. In these cases, fresh concrete is placed on hardened concrete. The interface that is formed between these two lifts of concrete is known as a...

Implications of distracted driving on driver behavior in the standing queue of dual left-turn lanes : an empirical study

Creator:: Marnell, Patrick Stanley
Abstract:: Driver distraction is a commonly observable phenomenon with a significant effect on the transportation network. Although the negative effects of driver distraction on safety are commonly studied, there has been little effort made to investigate the impacts of distraction on efficiency. This study will examine driver behavior in standing queues...

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...

Synergistic Effects of Alkali Silica Reaction (ASR) and Fly Ash on the Corrosion Characteristics of Reinforced Concrete Systems

Creator:: Mazarei, Vandad
Abstract:: Alkali silica reaction (ASR) and corrosion of reinforcement are two deterioration mechanisms in reinforced concrete (RC) structures. These deterioration mechanisms can significantly damage a RC structure and reduce its service life. Supplementary cementitious materials (SCMs) are commonly used to improve the durability of RC systems containing reactive aggregate that are...

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...

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...

Evaluation of desktop learning modules in civil engineering classrooms to promote inductive and interactive learning

Creator:: Buker, Kamilah E.
Abstract:: Students in undergraduate engineering programs typically do not synthesize content learned from disparate course work until the end of their final terms of college. As an example, in undergraduate civil engineering programs, transportation engineering concepts (e.g., geometric alignment, asphalt design procedures) and geotechnical engineering concepts (e.g., shear strength of soils,...

Evaluation of a Pedestrian Call Extension and Cancelation System at a Midblock Trail Crossing

Creator:: Milacek, McKenna
Abstract:: Signalized intersections often provide pushbuttons to call for pedestrian service to minimize conflicting movements between road users. Signalized midblock crossings typically increase safety for pedestrians in locations with high traffic volumes and multiple lanes in each direction. However, unnecessary vehicular delay occurs from “ghost” pedestrian intervals when someone activates the...
