AASHTO TSP•2 - Emulsion Task Force Indianapolis, IN
November 28, 2018 1

2. Background
Motivation: insufficient coverage of asphalt emulsions in undergraduate engineering curriculum
AEMA hired University of Arkansas (UA) to produce three online asphalt emulsions certificate programs
Introduction to Asphalt Emulsion
Application of Asphalt Emulsion
Manufacture of Asphalt Emulsion
Content level assumes a bachelor’s degree in any subject area
 April 2017
 January 2018
 August 2018
These courses are designed as on-demand and on-line: take any time, any place

3. Structure of each certificate
Ten lessons per certificate
Each lesson has
One Educational Brief ( pdf, can download, print)
Five videos that review key points of EduBrief
Quiz at end of lesson (unlimited tries)
Two exams in each certificate
Mid-term and final (can take each up to three times)
Two essays in each certificate, ensures each participant is actively engaged
15 Professional Development Hours (PDH) awarded on completion

4. Why asynchronous online certificate?
Asynchronous: unscheduled, on-demand
Highly specialized areas often not taught at undergraduate level
For example, asphalt emulsions
In past 5-10 years, movement toward online platform for workforce development
Younger professionals prefer to be able to learn from anywhere at any time
Content should be interactive
Read, watch, quiz, write
Very similar development process as South Carolina’s contract administration training program

5. Development process in six steps
Develop foundational information and content
Establish development team
Select development platform
Determine delivery methods and stylistic elements
Build modules
Conduct pilot testing
Advisory committee was established to provide feedback and approval in all six steps

7. 1. (cont) Some example learning objectives
Introduction to
Asphalt Emulsion:
Grading
Application of
Asphalt Emulsions:
Scrub seal and cape seal
Manufacturing of
Soap solution production 1
Recall the three standard specifications for asphalt emulsion
Determine proper usage of scrub seal and cape seals
List the components of soap solutions 2
Review the structure of a grading specification
Identify material section of scrub seal and cape seals
Describe special considerations for each component of soap 3
Grade an anionic asphalt emulsion
Examine design strategies of scrub seal and cape seals
Identify the steps in the proper sequence to prepare a soap solution 4
Verify the grade of a cationic emulsion
Understand construction of scrub seal and cape seals
Compare soap production in the lab, in a batch plant, and in a continuous plant 5
Grade a polymer modified asphalt emulsion -
Step 1 included a technical advisory group

8. 2. Establish development team
Funding and
technical review panel
Technical content
Instructional design

9. 3. Select development platform: Blackboard
Next lesson opens upon passing quiz, exam, or submitting essay

10. 4. Determine delivery methods and stylistic elements
EduBriefs: Print and read – 100+ pages of text
Videos reinforce EduBrief highlights
Content formatting consistent: red and yellow colors with UA and AEMA logos

11. Multiple external and internal iterations
5. Build modules
Utilized several existing sources of information
Basic Asphalt Recycling Manual, Shell Bitumen Handbook, Asphalt Emulsion Technology, and Bitumen Emulsions all heavily referenced
Technical writer editor reviewed EduBrief draft
External technical review committee approved EduBriefs and videos
Industry and government representatives
Global Campus built lessons into Blackboard
Multiple external and internal iterations

12. The six steps provided a solid platform for certificate development
6. Pilot testing
Group of volunteers performed soft rollout
Questionnaire after each lesson
Completion time, quantity and quality of material, functionality of Blackboard, etc.
Ensured that
Technical content correct
Length of each lesson appropriate
Blackboard working as designed
The six steps provided a solid platform for certificate development
