Multiscale characterization of asphalt concrete. Chemical, rheological, and damage characterization of asphalt binder; asphalt binder oxidative aging; asphalt modification; asphalt emulsions; asphalt mastics; fine aggregate matrix; coarse aggregate structure. Graduate course on Asphalt and Bituminous Materials or consent by the instructor.

Existing graduate courses cover concepts related to the Superpave design of asphalt concrete mixtures (CE 595: Asphalt Materials) and asphalt material constitutive behavior (CE 759). However, the existing courses do not cover phenomena related to local scales within asphalt concrete, which is critical to understanding the role of asphalt concrete constituents on overall performance and hence complements the other courses. The proposed class provides instruction how the different length scales of asphalt concrete are assembled, characterized, and modeled to infer how local scale phenomena affect overall behavior. A set of real experimental data has been assembled for each experimental method covered in lecture to offer the students hands-on experience applying concepts to analyze and model real data. This allows students to develop the skills necessary to apply the research tools covered in class in their own graduate research or professional endeavors.

This is part of the regular teaching load for Dr. Castorena.

The objectives of the course are to equip graduate students with the skills to study, characterize and apply knowledge regarding the composition, fundamental properties, and behavior of asphalt cements and emulsions, the role of mineral fillers and aggregates and their interaction with asphalt cements on asphalt concrete behavior, and the methods and analyses used to characterize asphalt binders, mastics, and fine aggregate mortars.


Student Learning Outcomes

By the end of this course, the students will be able to: 



  1. Explain the basic processes that are used to extract asphalt in petroleum refining.

  2. Relate changes in asphalt binder chemical composition and microstructure to expected changes in performance.

  3. Characterize and evaluate asphalt binders, emulsions, mastics, fine aggregate mortars, and coarse aggregate structure using commonly used test methods and models.

  4. Interpret and critique rheological data from Dynamic Shear Rheometer and Rotational viscometer experiments.

  5. Select production and material variables to alter to result in desired changes to the properties of asphalt emulsions.

  6. Evaluate the mechanisms by which asphalt modifiers alter asphalt mixture behavior. 

  7. Evaluate the mechanisms by which mineral fillers affect asphalt mastic behavior.

Note that the course has been offered as a 500 level special topics class. However, it is recommended that the course be offered at the 700 level in the future.

mlnosbis 8/10/2017:
1) See note from Doug Reeves at bottom of course reviewer comments.
2) Prerequisite note- are there graduate courses regarding what is listed? List those by prefix and number. Will the course be permission of instructor for all students?
3) Please explain why this is proposed as a 700-level doctoral course when it has been offered previously as a masters-level course.
4) Since this is a new course, please obtain a consultation from the College of Sciences. Please contact Dr. John Blondin, blondin@ncsu.edu, and he can facilitate a college review of the course. Enter consultation summary in the consultation summary field of the CIM form.
5) Student learning outcomes on the CIM Form should match syllabus exactly. Edit the syllabus to use more action/measurable language for the outcomes.
6) Syllabus should include topical outline and weekly schedule.

pjharrie 8/22/17 - will the students taking this be primarily PhD or Master's? That is what should decide the level. Other than that, I think Melissa and Doug's comments cover it.

Cassie Castorena's responses to mlnosbis:
1) The prerequisites have been revised in the syllabus. Information on reading material has been added to the syllabus.
2) There is a special topics course offered every year at NCSU that satisfies the pre-requisite. It will be submitted for adoption as a standard course in the near future and was formerly offered as CE 753 before transitioning to a special topics course to change to the 500 level in past years.
3) The difference between 500 and 700 level courses was not explained to me when I first arrived to NCSU so when I was instructed to offer a special topics course under the 595 listing, I did not question. However, the advanced nature of the course and the fact that it is targeted for PhD students makes the 700 level listing more appropriate.
4) I contacted John Blondin and received the following response: "Cassie, The College of Sciences has reviewed your proposed course and does not find any issues or concerns related to existing courses in our college."
5) The syllabus has been edited accordingly.
6) The topical schedule has been added to the syllabus.

Cassie Castorena's responses to pjharrie: The students who take this course are primarily PhD.

sarumug (Fri, 17 Mar 2017 02:06:49 GMT): Rollback: Update what we discussed?
sarumug (Fri, 28 Apr 2017 18:13:41 GMT): Rollback: Please revise based on our comments.
reeves (Wed, 09 Aug 2017 18:29:02 GMT): The prerequisites mentioned in the syllabus do not agree with the prerequisites in this document - update the syllabus. Say something about what sources of information will be used - readings from the research literature? Commercial studies? E-books? Websites? I understand there is not a textbook, but there must be some readings.
