Using the Long Term Pavement Performance Database in Pavement Design Courses

The Strategic Highway Research Program Long Term Pavement Performance (LTPP) database provides considerable information about a large number of pavement test sections. The information may be easily accessed using DataPave 2.0 software, available free from the Federal Highway Administration. This software provides information on approximately 3,000 sections, with several modules for data analysis and extraction. This paper describes the integration of LTPP DataPave 2.0 software into a pavement design course. The database was used at several points throughout the course, including lessons on traffic characterization, materials, reliability, performance, and design. Twelve Texas pavement case studies were used. Each student was required to complete an individual project requiring the use of the database. Student projects and student evaluations of the use of the DataPave 2.0 software in this course are also discussed. This paper provides sufficient information for interested faculty to implement the use of DataPave 2.0 in their own courses in pavement design and related areas.     

Survey of the National Civil Engineering Curriculum

This paper presents the results of a comprehensive survey of over 40% of the nation’s undergraduate civil engineering programs. This analysis is based on uniform data collected for accreditation and is principally concerned with three major groups of courses: (1) math and science, (2) general education, and (3) engineering topics. The analysis reveals what is currently being taught in our nation’s civil engineering undergraduate programs, what is not being taught, and the implications for future professional practice. The paper discusses how the average national curriculum has changed historically, how well the curriculum satisfies Accreditation Board for Engineering and Technology criteria, and what the current distribution of courses and topics says about the priorities of civil engineering education. Overall, the curriculum was found to be highly specialized in terms of technical subjects but lacking in focus regarding the liberal arts, professional skills, and systems thinking.     

Effect of Design and Site Factors on the Long-Term Performance of Flexible Pavements

Results are presented from a study to evaluate the relative influence of design and site factors on the performance of in-service flexible pavements. The data are from the SPS-1 experiment of the Long-Term Pavement Performance program. This experiment was designed to investigate the effects of HMA surface layer thickness, base type, base thickness, and drainage on the performance of new flexible pavements constructed in different site conditions (subgrade type and climate). Base type was found to be the most critical design factor affecting fatigue cracking, roughness (IRI), and longitudinal cracking (wheel path). The best performance was shown by pavement sections with asphalt treated bases (ATB). This effect should be interpreted in light of the fact that an ATB effectively means a thicker HMA layer. Drainage and base type, when combined, also play an important role in improving performance, especially in terms of fatigue and longitudinal cracking. Base thickness has only secondary effects on performance, mainly in the case of roughness and rutting. In addition, climatic conditions were found to have a significant effect on flexible pavement performance. Wheel path longitudinal cracking and transverse cracking seem to be associated with a wet-freeze environment, while nonwheel path longitudinal cracking seems to be dominant in a freeze climate. In general, pavements built on fine-grained soils have shown the worst performance, especially in terms of roughness. Although most of the findings from this study support the existing understanding of pavement performance, they also provide an overview of the interactions between design and site factors and new insights for achieving better long-term pavement performance.     

Teaching Engineering Surveying in a Civil Engineering Program: Curriculum, Pedagogy, and Assessment

As engineering surveying is highly concerned with its intensive involvement in the construction of roads and bridges, drainage systems, buildings, railways, and tunnels in civil engineering, the subject of engineering surveying is being offered by the Department of Land Surveying and Geo-Informatics to all undergraduate students who are taking the Bachelor of Civil Engineering Degree Program in the Department of Civil and Structural Engineering at The Hong Kong Polytechnic University. Under the new outcome-based curriculum and work-integrated education requirements, the curriculum, pedagogy, and assessment for the subject are described here by answering the questions of “what are the goals and objectives of the curriculum,” “what should students learn,” and “how should it be learned, taught, and assessed.”     

Information Technology in Civil Engineering Curriculum

The fast-moving world of information technology confronts the civil engineer with constant change. This creates challenges for educators and students because rapid change requires curricula to be flexible and educators to gain competency and access to new equipment and software. Whereas a decade ago, civil engineering educators debated how to teach “programming,” the picture is now much more complex. The paper reports on how information technologies are changing the practice of civil engineering and offers a new framework for integrating next-generation information technology into the civil engineering curriculum at the department level.     

Architectural Engineering Curriculum at Missouri University of Science and Technology

Missouri University of Science and Technology (formerly, the University of Missouri-Rolla) began a Bachelor of Science degree program in architectural engineering in the fall of 2002. The 4-year academic program’s curriculum at Missouri S&T requires the students to complete 128 semester credit hours during a period of eight semesters, with options for technical electives in one of four focus areas: structural engineering, construction engineering and project management, environmental systems for buildings, and construction materials. This paper presents the architectural engineering curriculum at Missouri S&T. It discusses the objectives of the curriculum, the constraints upon its structure, along with challenges that faced the establishment of an architectural engineering program.     

Fluid Mechanics: An Essential Part of an Environmental Engineering Curriculum

In this paper we discuss teaching fluid mechanics to civil and environmental engineering majors at both the undergraduate and graduate levels. Fluid mechanics is a key course in environmental engineering that ties together the physical aspects with chemical and biological aspects. We survey the historical development of the role of fluid mechanics in environmental engineering, discuss current needs and curriculum, and point out areas for potential improvements.     

Capstone Course in an Integrated Engineering Curriculum

The Dept. of Civil and Environmental Engineering at the United States Air Force Academy has developed a capstone senior level integration experience that blends technical aspects of an engineering design with construction and realistic issues of modern society. Technical designs accomplished by the students, prior to taking the capstone course, form the technical basis of the capstone design experience. The students review the technical design and prepare the project for construction through incorporating engineering standards and considering realistic issues. Issues considered include economy, constructability, and environmental aspects, as well as ethical, health and safety constraints. The students prepare a final design report and make an oral presentation to an interdisciplinary panel of engineering faculty. This capstone course is the culmination of a total integration experience, which includes a hands-on field engineering course, and two years of a rigorous engineering design curriculum.     

Implementing an Inclusive Curriculum for Women in Engineering Education

Engineering faculty are urged to be “inclusive” when teaching classes of diverse students. Research has shown that an inclusive approach not only assists the progress of socially and culturally underrepresented students, but it will also broaden the perspectives of all students, and thus improve the overall quality of an engineering program. The writers of this paper have collaborated over a number of years at the University of South Australia to make engineering education more inclusive. This process commenced with an institutionwide project to develop inclusive curricula by improving the understanding and practice of faculty, and developing guidelines to assist them in restructuring their courses to become more inclusive. In the engineering departments, the process was further developed through staff workshops to assist faculty with the redevelopment of course curricula using the university guidelines, as well as the collection and dissemination of material and examples appropriate for engineering programs. This paper describes some of these methods in more detail, as well as the obstacles the writers have encountered and the devices they have used to overcome objections and impediments. Specific examples from civil engineering are included.     

Incorporation of Sustainability Concepts into a Civil Engineering Curriculum

The need arises to equip engineering students with a wider horizon of concepts in terms of environmental, economic, and social attributes, for decision making of sensitive to sustainability issues. Pedagogic frameworks have to address a multidisciplinary analysis of sustainability. This paper addresses the rationale behind the recent integration of sustainability concepts into an undergraduate civil engineering curriculum in Hong Kong. Incentives and barriers for implementation of the curriculum are addressed. A team-based design project with a problem-based learning approach is highlighted. The initial results of stakeholder evaluations suggested that multidisciplinary skills developed during the learning process might contribute significantly to pertinent knowledge on sustainability.     

Integrating Ethics into the Engineered Construction Curriculum

Equality, life, liberty, the pursuit of happiness, security, civic duty, justice, honor, and the rule of law are some of the widely held values in society. These are the values engineers must adopt to comply with regulations. Unfortunately, there is a lack of awareness in construction education regarding how to integrate social awareness and ethical behavior into professional practice. Several challenges facing construction engineering educators are how to develop strategies that will raise the awareness of students regarding ethical issues related to construction and how to provide a framework to make ethical decisions. Social values should serve as the basis for university-level ethics instruction. The objectives of this paper are to discuss the various disciplines that are available for use in developing course material and classroom presentations, and to describe a framework for making ethical decisions. Problem solving in ethics is a skill that is very much needed by students, but is quite difficult to teach. The approach described herein uses real world construction ethics cases and invited guest lectures from the construction industry plus multiple required and elective courses explore ethical theories, concepts of critical thinking, and major ethical issues related to the construction industry.     

Globalization Challenges, Legacies, and Civil Engineering Curriculum Reform

Across nations and industries, numerous changes are taking place due to globalization. Naturally, the effects are channelled back to the academic world and prominently felt at the level of higher learning in view of its constant contact with the industries. Universities and institutions have to reassess the adequacy of their existing curricula in fulfilling the needs arising from globalization. With reference to issues encountered in southeast Asia, this paper examines the necessity to rethink the curriculum of a baccalaureate degree in civil engineering and presents some recommendations for revamping the curricular structure. The context discussed is most relevant to small, developing countries, but generally concerns those countries with a legacy of educational systems similar to this region. One rising trend is the move toward a general engineering education at the undergraduate level; a professional degree is emphasized only at the master’s level. More management-related subjects may be included in the undergraduate curriculum to equip engineers with skills to cope with globalization challenges.     

Student Learning in a Multidisciplinary Sustainable Engineering Course

An existing multidisciplinary course on sustainable engineering in developing societies was expanded to include sustainability issues and challenges faced in the developed world. The new course consisted of independent modules on general background, sustainability concepts and tools, sustainable water and waste systems, sustainable energy systems, sustainable agricultural and food systems, and sustainable building systems. The course included a semester-long project experience conducted in interdisciplinary teams. Projects were sourced from local businesses and institutions or from organizations involved in international development. Course evaluation included an end-of-semester self-assessment by students and an analysis of project reports. Thirteen out of 18 students surveyed (72%) agreed that their ability to consider techno-economic, environmental, and social aspects of sustainability was improved as a result of the course. An improved student understanding of aspects of sustainability and its measures was also evident in student project reports.     

Changing the Status Quo in Environmental Engineering Education in Response to Emerging Markets

The job market and skill needs have been expanding for environmental engineers requiring more interdisciplinary training and global citizenship. The 1970s was a decade of regulatory activities, the 1980s was a decade of major environmental disasters, the 1990s was a decade for global awakening, and the first decade of the 21st century is becoming the decade of concern for increasing global environmental stress. In parallel with the environmental trends, the environmental engineering programs have evolved from strictly water/wastewater focus to interdisciplinary programs with a wide selection of courses such as computer science, meteorology, aquatic biology, and ecology in addition to the classical environmental engineering curriculum. Advancements in science and technology, changing demographics, new delivery structures, changes in educational programs and policies, new regulatory requirements, increased global interactions, and recent large scale events with significant environmental impacts have increased the needs for engineers who are trained in environmental engineering discipline with adequate skills for addressing the emerging challenges. This technical note presents the emerging job markets and the corresponding skill needs for environmental engineers to respond to current and evolving environmental challenges both at regional and global scales.     

Framework for Evaluating the Performance of Engineering Consultants

The evaluation of consultant’s performance is crucial to the success of a consulting assignment especially when today’s construction projects are becoming more sophisticated, large-scale, and risky. However, since individual clients have developed their own consultant’s performance evaluation (CPE) procedures, the sharing of performance information, though desirable, may not be too meaningful as the results of evaluation could be inconsistent. There is a need to examine whether a unified framework can be derived for CPE. The aim of this paper is to improve the transparency and rigorousness of CPE through the establishment of an evaluating framework for gauging the performance of engineering consultants. In this paper, a comprehensive set of evaluation criteria is identified, and the significance of these criteria is discussed through an empirical survey. Then, a multicriteria model for evaluating the performance of engineering consultants is presented. The results indicate that once an acceptable CPE framework is devised, the performance scores can be utilized for various purposes, including monitor and control, incentive and sanction, preselection, technical assessment, and bid evaluation.     

Preparedness of Engineering Freshman to Inquiry-Based Learning

Educational experts, past and present, urge engineering colleges nationwide to transform their pedagogical paradigm from a predominantly lecture- to an inquiry-based teaching approach. Written comments by two seniors, deploring having to read and write in a required course of an ABET accredited program, highlight a common expectation of today’s students. Presented are the disturbing results of a survey that assessed the level of learning skills exhibited by 1,020 engineering freshmen. Time management not only surfaced as needing drastic remediation but it also correlated with the level of students’ motivation to succeed in college. Problems with poor time management were listed by 25% of the freshman cohort at the end of the first semester. From monitoring the submittals of online homework it was learned that timeliness corresponded with the final grade achieved in a course. The work presented in this paper indicates that universities need not only to address the students’ learning preferences but also equip them with the skills necessary to engage actively in the knowledge-building process, a necessary sea-change in engineering education.     

Crisis of Civil Engineering Education in Information Technology Age: Analysis and Prospects

The brightest students entering postsecondary education are often attracted by routes other than engineering that are perceived more likely to yield careers of higher prestige and greater returns. For civil engineering in particular, this is further compounded by the fact that the field is not traditionally viewed as a high-tech discipline. Thus, student quality, enrollment, and research funding in civil engineering programs have been declining across North America. The conservative construction industry is part of the problem; adjustments of this aging cartel to the new economy are still at the embryonic level. Civil engineering educators are facing the question, How do we change the “hard hat down in the ditch” image of civil engineering in the minds of the new information technology generation? This paper presents an analysis of possible causes of this problem and a vision for potential future solutions.     

Determining the Content of the First Course in Transportation Engineering

Transportation engineering constitutes a required portion of the civil engineering curriculum at over three-fourths of undergraduate civil engineering programs in the United States. The input of practicing transportation engineers is a critical source of information in determining the content of the first course in transportation engineering. A new survey was conducted in which respondents ranked 31 potential course topics by importance. The results are compared to a similar survey conducted 20?years before to determine which topics have increased in importance, which have become less critical to cover, and which continue to remain of high priority. Topics such as traffic safety and traffic flow characteristics are of considerably higher priority today than 20?years ago, while topics such as geometric design of highways and highway capacity studies continue to be of great importance. Preparation for follow-up and graduate coursework, for the Fundamentals of Engineering and Professional Engineer examinations, and issues of local setting are also considerations in determining the content of the first course in transportation engineering.     

Integrating Management Breadth in Civil Engineering Education

At the beginning of the 21st century, there is a wider awareness that the civil engineering industry has become a global industry. The rapid increase in foreign ownership of firms in the United States along with the globalization of economic markets is reminding professionals that they must be aware of global events before they impact local operating conditions. In response to these developments, university programs must begin to broaden their focus to include subjects that address new economy realities. Specifically, the time to begin exposing students to management topics such as entrepreneurship, financial management, and global economics has arrived. If the civil engineering industry is going to evolve into a new economy business, it will require individuals who are as comfortable with the financial and technological components of the business as they are with design or construction fundamentals.
