They provide unique characteristics essential for fulfilling the intended functionality of preserving bridge decks from the deicers-induced corrosion and deterioration problems. Typically, the LMC overlay has higher initial cost than the MSC overlay; but the LMC overlay is considered more durable with better performance. The two major drawbacks with the LMC and MSC overlays are their high cost and their cracking tendency. Adding synthetic fibers to bridge deck concrete overlays may improve the resistance to cracking with slight increase in the initial cost. In this study, the feasibility of using fibrous fly ash concrete (FAC) overlay was explored as part of a state DOT research project intended for investigating the advantages of various types of fibrous additives on the performance bridge deck concrete overlays. Experimental test results obtained for fibrous FAC overlay mixtures along with fibrous LMC and MSC overlay mixtures were presented herein. Comparisons were made among key performance characteristics including compressive and flexural strengths, permeability, shrinkage, bond strength, and residual strength. It is important to point out that this research is pioneering in terms of using fibrous FAC overlay that could be a potential sustainable overlay system for preserving bridge decks for extended service life with lower cost and without adverse impact on the environment.

Financing is the most crucial piece of the construction projects. Most privately sponsored projects are funded by owner equity. However, this is not the case for non-profit organizations. Many nonprofit owners turn to organizations offering grants for their capital improvement projects as a major source of funding. Much consideration and effort are expended to obtain grants. Many grants carry specific regulations that must be obeyed to qualify and obtain funding. Therefore, finding available funding has become an increasingly difficult endeavor. Limited literature exists to guide non-profit organizations in construction projects. This research is dedicated to investigating the non-profit organizations and their fundings. The research will present a practical investigation based on literature analysis and historical cases for non-profit development projects.

This research project investigated the potential benefits of synthetic fibrous additives with regard to the performance of bridge deck concrete overlays. Determining practical dosages and types of synthetic fibers that have the ability to enhance overlay performance, while maintaining convenient constructability without complications during mixing and finishing, was a major mission of this research. The project also outlined critical issues essential for successful and durable overlay applications with minimal cracking and delaminations. Various micro-and macro-fiber combinations were added to the fibrous overlay mixtures, resulting in 13 fibrous mix designs (nine LMC, two MSC, and two FAC). An extensive experimental laboratory program was then conducted to evaluate the major performance characteristics of each overlay mix design in terms of workability and finishability, compressive and flexural strengths, shrinkage, toughness, permeability, and bond strength. For further evaluation of the constructability of fibrous overlaytaking into consideration actual field conditions-demonstration bridges were selected and received fibrous overlays through actual IDOT contracts. Life-cycle cost analyses were also conducted to assess potential savings from incorporating fibrous additives within the concrete overlays. This research is pioneering in terms of using fibrous FAC overlay, which could be a potentially sustainable overlay system for preserving bridge decks with lower cost and minimized adverse environmental impact.

The project statement required the use of Excel in developing a program for highway geometric design; from simple curves to compound curves; both vertical and horizontal. In addition, the goal of this project was linked to ABET outcomes that address the ability of students to design a system, component, or process to meet desired needs within realistic constraints and, measure student's ability to use the techniques, skills, and modern engineering tools necessary for engineering practice. The paper presents the process of developing the spreadsheet step-by-step, the command used, challenges, and skills and lessons learned by the author and other student in the class. As a result, a simple and efficient spreadsheet to design vertical curves and simple and compound horizontal curves including default values was developed. The results of the survey suggested a major improvement of students' skills in Excel in general and in developing engineering design in particular. Major improvements were found in using functions and nested If statements. The least skills acquired were in using the Absolute and Sum commands and graphing in Excel. Most of the students either knew these commands before the class or they were familiar with them. Finally, this project enabled students to advance their knowledge of spreadsheets while learning important transportation engineering topics.

It requires conservation of the natural resources and energy, while minimization of the impacts of a product or a system to the natural environment to a level within the nature’s self-sustaining capacity. In typical classroom teaching, students have rare chances to practice the concept of sustainability. However, the capstone projects for senior engineering students provide a valuable opportunity for them to utilize and to practice the concept in a system or in a technological design, build and evaluation. In this paper, a group of Civil Engineering students designed, built and tested a chemical-free multimedia filtration system to treat the St Joseph River water for clean water supply. Smallscaled water treatment systems are important supplements to centralized drinking water supply, because of their minimal or even no chemical usage, low start-up and operation costs, high mobility, and the ability to be built economica...

Consequently, a comprehensive knowledge of the risk factors identified from crash data analysis becomes critical in reducing risk levels and preventing severe crashes in work zones. This study focuses on the 2016 severe crashes that occurred in the State of Michigan (USA) in work zones along highway I-94. The study identified the risk factors from a wide range of crash variables characterizing environmental, driver, crash and road-related variables. The impact of these risk factors on crash severity was investigated using frequency analyses, logistic regression statistics, and a machine learning Random Forest (RF) algorithm. It is anticipated that the findings of this study will help traffic engineers and departments of transportation in developing work zone countermeasures to improve safety and reduce the crash risk. It was found that some of these factors could be overlooked when designing and devising work zone traffic control plans. Results indicate, for example, the need for appropriate traffic control mechanisms such as harmonizing the speed of vehicles before approaching work zones, the need to provide illumination at specific locations of the work zone, and the need to establish frequent public education programs, flyers, and ads targeting high-risk driver groups. Moreover, the Random Forest algorithm was found to be efficient, promising, and recommended in crash data analysis, specifically, when the data sample size is small.

IPFW is the largest public university in northeastern Indiana, serving more than 12,000 students. The civil engineering program is the most recent addition to the Department of Engineering, which offers B.S. degrees in civil, computer, electrical, and mechanical engineering. Most of engineering students attend collage as part time and usually commute to campus. Sometimes, it is hard for them to perform well in homework and assignments due to limited access off campus to computer software needed by their classes. In order to help students in improving their academic performance, a pilot study was conducted in the spring 2007 semester to evaluate the impact of providing students with remote access to proprietary software need for their assignments. This paper presents the result of the pilot study of remotely accessing engineering software using Citrix server. There were two software packages available for use: AutoCAD and Matlab. The impact of Citrix server on students' performance was evaluated using two surveys: initial and final surveys. Both surveys were conducted in two sections of two freshmen courses taught during the spring semester: Graphical Communications and Spatial Analysis and Computer Engineering Tools for Engineering. Students usually use AutoCAD in the graphic class and Matlab in the engineering tools class. Most the students participated in the survey were freshmen, male, full time students, employed, living off campus with an average commute of 15 miles, do not own a copy of the software, and have Internet access at home. The paper presents a summary of the findings for both surveys. In conclusion, most of students agreed that remotely accessing software package using Citrix server has reduced their commuting time and provided them with more time to study at home; improved their grades in general and homework grades in particular; improved their grades in all courses in general and Citrix related courses in particular; and their experience with Citrix was excellent and recommend strongly that the college adopts the server permanently.

To increase strength and durability, various additives have been used in the industry. Crystalline Silica which has fine particles is one of these additives widely used in concrete construction. In the US, roughly 2.5 Million people are dealing with concrete in manufacturing concrete blocks, concrete cutting, or other concrete related activities such as trending, drilling, cutting, or sawing concrete. The Occupational Safety and Health Administration (OSHA) has recently stated that, Crystalline Silica in concrete is hazardous to human health. The people in risk are inhaling the silica particles and may develop silicosis, lung cancer, chronic obstructive pulmonary disease, or kidney diseases. Recently, OSHA developed new respirable crystalline silica standards for construction. With this new regulation, Crystalline Silica quantities will be limited. With this motivation, this research work deals with an experimental investigation of concrete ingredients to identify the effects of silica in construction. The paper experimentally investigates the effects of crystalline silica in concrete. The current design standards have been studied to reveal the efficiency of the silica in concrete. Compression strength and velocity tests have been used in the experimental set up. A better identification of the silica effect in concrete will help in decision process for the stakeholders in concrete industry.

Transportation agencies, however, have not yet recognized the full capabilities of GIS. The purpose of the GIS cost estimation project is to research the possibilities of analyzing data through the power of geographic management. The enhanced data management would assist in improving project cost estimation. Typically, state highway departments rely heavily on historical bid data to estimate construction projects. A systematic information collection, organization, and storage process must be used so that relevant historical cost data can be retrieved. Data collection and storage have been done for years but their usefulness at times appears worthless, primarily because of the amount of time required to page through and assimilate reams of compiled data. Analysis would be greatly simplified if one could visualize the data graphically. Using such technology should assist in easing the ever-incre...
