Estimation Of Annual Average Daily Traffic On Local Roads In Kentucky, William Nicholas Staats

Theses and Dissertations--Civil Engineering

Annual average daily traffic (AADT) is used to estimate intersection performance across Kentucky. The Kentucky Transportation Cabinet (KYTC) currently collects AADTs for state maintained roads, but lacks this information on local roads. A method is needed to estimate local road AADTs in a cost-effective and reasonable manner. A literature review was conducted on AADT models and found no models suitable to Kentucky. Therefore an AADT model using non-linear regression was developed for local roads in Kentucky

This model divided the state into three regions utilizing Kentucky’s highway districts. This partitioning accounted for geographic and socioeconomic variability across the state. Each …

Tier 1 Highway Security Sensitive Material Dynamic Risk Management, Steven Douglas Kreis

Theses and Dissertations--Civil Engineering

Each year, over 2 billion tons of hazardous materials are shipped in the United States, with over half of that being moved on commercial vehicles. Given their relatively poor or nonexistent defenses and inconspicuousness, commercial vehicles transporting hazardous materials are an easy target for terrorists. Before carriers or security agencies recognize that something is amiss, their contents could be detonated or released. From 2006 to 2015, the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) recorded 144,643 incidents involving a release of hazardous materials. Although there were no known instances of terrorism being the cause, accidental releases …

Thermal Envelope Analysis Of Local Authority Low Rise Housing Based On Stock Aggregation Theory Using A Remote Feature Extraction Technique., James Pittam

Theses

Understanding the buildings thermal envelope is paramount to analysing existing problems which facilitate cold bridging and low surface temperatures. As no detailed housing stock database is in existence in Ireland which describes the geometrical configuration of the existing housing stock, and to create one would be a major challenge, this research set out to develop a high speed remote cataloguing and geometrical data extraction methodology to build such a database. Replacing traditional measurement methods with a remote method allows for the rapid extraction of fagade information. A remote surveying process is proposed named, the Virtual Survey Method, for the classification …

Laboratory Exercise- Mapping The Risk Of Structural Failure In Schools Due To An Earthquake, Joel Barker, Kimberly Sowards, Casey Webb

Engineering Applications of GIS - Laboratory Exercises

Utah’s present geology has been greatly dictated by tectonic stresses that have occurred over the last 0.7 Ga. A determining factor in much of this Geology is the Hingeline that runs through Salt Lake County. Throughout the history of the western North America, this has been an important weak zone. It is no surprise that this same zone is now home to the Wasatch Fault System, which accommodates some of the extension of Western North America. The steep mountains facing west toward Salt Lake City were formed from the tectonic processes of the Fault. The Wasatch Fault is a normal …

Precast Full-Depth Deck Panels Supported On Inverted Bulb-Tee Bridge Girders, Michael James Mingo

Electronic Theses and Dissertations

The South Dakota Department of Transportation (SDDOT) currently uses precast double-tee bridge deck systems for many of its county bridges because they are economical and fast in construction. Current bridges are designed for a service life of 75 years. However, many double-tee girder bridges are deteriorating and some need total replacement after 40 years in service. Furthermore, the double-tee bridge system only has one supplier in South Dakota. Alternative durable precast or prefabricated bridge systems are needed to provide more options to local governments when designing a new bridge. Different alternatives will also give local governments more flexibility to select …

An Overview Of The Development Of Cement-Based Batteries For The Cathodic Protection Of Embedded Steel In Concrete, Aimee Byrne, Niall Holmes, Brian Norton

Conference papers

This paper presents an overview of the cement-based batteries developed in DIT for use in the cathodic protection of embedded steel in reinforced concrete undergoing chloride-induced corrosion. Cathodic protection delivers an external current (approximately 20mA per m2 of embedded steel) which effectively polarises the internal current generated during corrosion. The batteries developed in DIT comprise of a cement-based electrolyte containing different additives including sand, aggregate, salts, carbon black and plasticiser with protruding anode and cathode metal plates. These batteries produced an initial electrical output of 1.5V and 23mA through a 10 resistor as measured using data acquisition units and a …

Using Photovoltaics To Power Electrochemical Chloride Extraction From Concrete, Sean Bond, Lynette O'Callaghan, Niall Holmes Dr., Brian Norton

Conference papers

Corrosion of embedded steel in reinforced concrete (RC) is a world-wide problem, that reduces structural performance and lifespan. Chloride attack may be a result of seawater, de-icing salts or contaminated admixtures, brought on by ingress of chlorides into the concrete. Electrochemical Chloride Extraction (ECE) is a non-destructive treatment for contaminated RC structures, that due to uncertainty of treatment times and applied current densities, is only 50% effective. It is often diesel powered has an environmental impact and often very costly due to the long treatment times. To improve the efficiency of ECE the influences of concrete resistance, cement type and …

Modeling Long-Term Deformations Of Unbound Pavement Materials Using The Miniaturized Pressuremeter Creep Data, A. M. Shaban, P. J. Consentino

Mechanical and Civil Engineering Faculty Publications

This research was undertaken to study the predictive capability of the pressuremeter test for characterizing in situ creep behavior of unbound pavement layers. Although the creep potential of granular pavement materials is less pronounced than fine-grained soils, consideration of actual creep deformations in the pavement evaluation process will improve long-term pavement performance. In this investigation, the long-term deformations determined from laboratory one-dimensional creep tests were compared with those investigated by field pressuremeter tests. The pressuremeter test consisted of inflating a cylindrical probe incrementally up to a given stress level, and then maintaining the pressure constant for a 5-min single stage. …

Validation Of Integrated Coast-Ocean Model Cche2d-Coast And Development Of Wind Model, Afshin Gazerzadeh

Electronic Theses and Dissertations

The eastern and southern coastlines of the United States are two of the most cyclone-prone areas of the world. The effects of tropical cyclones vary mainly depending on wind intensity and geological features of the coast that it is crossing. Higher winds potentially generate higher storm surges and consequently larger floods occur along the coastlines. Therefore, it is critical to accurately predict winds, storm surge, and waves associated with a hurricane. In the present study, an integrated coastal and ocean process model, CCHE2D-Coast, is validated by assessing the model’s capabilities in simulating coast-ocean circulations driven by the astronomical tides on …
