AEMA ITC Report for the 2015 PPRS Meeting in Paris
1) Regular Business a) A document addressing proper sampling, shipping, reheating and sampling the sample for testing has been created. There were some revisions and a disclaimer added. It is attached for the final BOD review. If approved, it will be available in the members only section of the
AEMA website.
Action: - submitted for BOD review
Due: ASAP b) RPG Update
Action: - Distributed to Mark Ishee, Mark McCollough and Diane Franseen for final review
- In the process of making sure terms are in agreement throughout the document .
Responsible person(s): Mark Ishee, Mark McCollough, Diane Franseen, Mike Hemsley
Due: Original Nov 2014 for Final Review now Nov 2015 for completion. c) Continued Updates for New Methods and Specs from Emulsion Task Force/Group. AMRL conducted round robin testing on the last proficiency sample that was distributed to AMRL labs.
I have obtained the statistical information from AMRL. The results look good and the actual statistical data will be presented in the ITC session. We will also be conducting another round robin with AMRL doing the same testing plan for the 2015 AMRL Emulsion Proficiency Sample.
We will again be encouraging our member companies to participate.
Action: review new methods, tests and specs
Responsible person(s): Arlis Kadrmas
Due: ASAP / ongoing d) AEMA ITC Round Robin Groups are still in a holding pattern for the time being with AMRL round Robin data pending.
Action: - evaluate AMRL data upon return of initial data.
Responsible person(s): Arlis Kadrmas and Kevin McGlumphy
Due: ASAP / ongoing e) Educational Committee – The committee would like to recommend that AEMA pursue the web based training with the FHWA. A recommended topic is “Safety, Storage, Handling and
Transportation of Asphalt Emulsions. The Committee is also pursuing information from
Universities on curriculum or programs being used for teaching about Asphalt Emulsions. The
Committee is also requesting information on what type of curriculum is needed
Action: collect presentations and educational material. Start working with FHWA on web based training.
Responsible person(s): Barry Baughman
Due: ASAP / ongoing f) Asphalt Emulsion Recovery Method “B” – This method is currently considered acceptable for emulsion residue recovery and subsequent DSR testing. An ASTM method is being developed. Initial thoughts are that an ASTM method is 12 to 18 months away from balloting.
Action: continue to contribute to the effort of writing the method.

AEMA ITC Report for the 2015 PPRS Meeting in Paris g) There is a group that is recommending ash content as a replacement for solubility of emulsion residues. The issue here is that the polymers in the emulsion residues clog the filter paper that is used in the solubility test due to the polymers not being soluble in the solvent that is used. The un-dissolved polymers are subsequently counted as insoluble material. Since the solubility test is an indicator of the quality of asphalt being used, as well as the Ash content, substitution should not be an issue. It has also been found by the CTAA along with some member companies that the ash content is a suitable replacement for solubility. Data has been gathered and a presentation has been put together and will be presented at the ITC Committee session at PPRS. Initial work indicates that a 1% maximum ash content would be acceptable.
Action: Gather Data from plants and CTAA and present to ITC
Responsible person(s): Arlis Kadrmas Diane Franseen
Due: ASAP / ongoing h) At the ASTM meeting in December, Arlis gave a presentation on VOC’s in asphalt emulsions.
This presentation is based off of work that has been ongoing at BASF. BASF was able to determine relationships of distillate levels, which are seen in the distillation process, to VOC’s in an asphalt emulsion. The only issues remaining are the different types of solvents and the levels of those solvents as related to the ones tested at BASF.
Action: Present data to ITC for review
