Objective:
The primary objective is the enable the students to develop a thorough understanding of appropriate mechanical, physical, and chemical properties of various materials commonly used in real civil engineering applications. Materials to be discussed include, but not limited to, aggregates, cements, concrete, timber, asphalt, metals, and fiber reinforced plastic composites. Weekly laboratory sessions complement the lectures and provide hands on experience with chemical, physical, and mechanical tests on metals, aggregates, cements, and concrete.
Outcomes:
With the successful completion of the course, the student should be able to:
q Recognize the industry standards and guidelines that are utilized in testing civil engineering and construction materials
q Distinguish between various aggregate materials based on their physical properties
q Determine appropriate aggregate gradations from sieve analysis and necessary blending proportions to meet desired specifications
q Identify the basic raw ingredients used in cement and chemical compositions of the most common types
q Design a concrete mix in accordance with ACI and/or PCA procedures
q Distinguish between various admixtures and their effects on concrete mixtures
q Distinguish between hard and softwood and list the important physical and mechanical properties of wood
q Identify asphalt cements and distinguish between hot-mix asphalt, cutbacks and emulsions
q Identify the basic requirements for a HMA design
q Identify the primary differences between Marshall Mix Design and SuperPave design and testing procedures
q Develop the ability to conduct laboratory experiments, record data, and perform appropriate calculations and analysis for civil engineering materials according to the associated ASTM standards and reporting procedures
q Work as a team member and gain insight on the benefits of working together toward a common goal of accurately and timely project completion
q Effectively communicate with team members during laboratory sessions, stressing appropriate safety procedures in handling equipment and performing work in and around a moving equipment

Homework and laboratory assignments as well as a report will be made throughout the semester. All homework must be submitted at the start of class or laboratory on the assignment date. Late homework is not acceptable except for unusual circumstances, e.g., an excused absence. Checking of your e-mail is required on a daily-basis for any additional information.
The students are required to submit a report that should be completed before the end of the semester. A presentation will be prepared and will be given before the final exam. The instructor will assign a presentation topic to each group of students.
Two exams and a final will be given during the course of the semester. Exams will be closed book and closed notes, with the exception that a portion of the 2nd and the final exams may be open. No makeup exams will be given with the exception of unusual circumstances (severe injuries, family emergencies, etc.).
Grading Policy:
Homework and presentation 10%
Lab Assignments 10%
Reading Assignments and Report 10%
Exam 1 20%
Exam 2 20%
Final Exam 30%
Letter Grade Scale:
90-100 A

The instructor does reserve the right to slightly lower these numbers based on class groupings.
Engineering Ethics:
It will be assumed that each student subscribes to a professional code of ethics that is the basis for his behavior in class. Any and every case where these ethics are violated will be dealt with according to the student handbook and the associated provisions of the university.
Additional Information:
[1] Arrangements for inviting guest speakers from the academia or industry will be made. The specialty of the speakers will be in the area of concrete and/or asphalt.
[2] The instructor will give presentations on the application of enhanced material properties on advancing the civil and bridge engineering practice and on the applications of new composite materials on advancing the CE practice.
[3] A field trip to the WVDOH Materials Testing Laboratory, Charleston, will be arranged:
[4] There will be regular homework and lab assignments. The students are required to work in preparing a report during the semester. The completed report has to be submitted before the end of the semester.
[5] You are expected to provide your homework in engineering papers - not a Xerox copy.
[6] The purpose of the reading assignments is to stimulate interest in the subject matter. Therefore, the instructor expects that you will read it thoroughly and prepare your questions. You may ask the instructor during the office hours for any question or clarification. This should in no way inhibit your asking questions at the end of the class.
[7] Although you are expected to attend all classes, the instructor accepts your absence for one session provided that an advance notice will be given, unless this is unavoidable. Absence without an advance notice will lead to have a lower grade.
