III. Approval of Technical Section Minutes2017 Mid-Year Minutes distributed with this agenda as Attachment A (Pages 5-22).

IV. Old BusinessA. SOM Ballot Items

1. Outstanding items from Mid-Year Meetingi. T48 Flash Point Temperature 219 C proposed. Did not make it to TS ballot due to

technical issues in just updating the standard for publication (figures). So a cleanversion was not available. (Attachment B, Pages 23-31) Propose a concurrent ballot.

ii. M 320 Revision to Note 4 PA to recommend revised note.B. TS Ballot #1

Ballot Results and all comments are included as Appendix C (Pages 32-83). 1. Item Number: 1 (1 Negative - GA)

Description: Ballot to revise and update R 15, "Standard Practice for Evaluation of Asphalt Additives and Modifiers." Sent back to GA with explanation requesting their input.

2. Item Number: 2 (1 Negative - PA)Description: Revise M 332, "Standard Specification for Performance-Graded Asphalt BinderUsing Multiple Stress Creep Recovery (MSCR) Test to remove the elastic component. This item istied to Item #3 to create a new standard practice for the elastic component.

3. Item Number: 3 (2 Negatives PA, NV)Description: Ballot to add a new standard practice for the elastic component removed from M 332.

4. Item Number: 4 (No Negatives)Description: Ballot to revise TP 102, Provisional Standard Test Method for Asphalt Release Agents. Move to SOM Ballot with Changes. Propose moving to a Concurrent Ballot for a fullStandard.

5. Item Number: 5 (1 Negative - NV)Description: Ballot for Provisional Test Method for Performance Graded Asphalt Binder for Surface Treatments.The following attachments are included:

An updated version of the specification, AASHTO SPG Spec Hot Applied 12-6-2016.pdf,that was balloted last year at SOM for a new ballot;

The ballot comments with responses to address them, TS2b 2016-1 Results-withcomments addressed.pdf;

Tech Section 2b Page 3 of 91

A presentation from the researcher, Dr. Amy Epps-Martin of TAMU/TTI, ShortCourse_Oct16_SPG_AEppsMartin_REVISED;

Original research reports, 0-6616-1, 0-6616-s. and 1710-2Final.The new spec:

1) Uses 6 degree increments for high and low temperatures. This reduces the number ofgrades.

2) The grades are offset from PG by 3 degrees to reduce confusion.3) Changes the requirement for phase angle to a UTI of 86 or more. This old

requirement of 89 does not exist in this 6-degree increment scenario. So I had tochoose to go up to 92 or down to 86. 86 means more materials are modified (moreconservative and what users want more modified binders).

4) Addresses the other comments that were mostly editorial.

C. Task Force Reports

Task Force 15-01 (T 48) Task Force members are Maria Knake (AMRL), Bill Bailey (Virginia), Jerry Peterson (Texas), and Ron Horner (North Dakota). Task Force to consider rewrite of T 48. The task force provided a draft specification for consideration.

Task Force 16-01 - Review ETG recommendations for elastic response, T 350, and M 332. Barry Paye(WI), and Matt Corrigan(FHWA). The ETG is proposing a separate standard practice for evaluating elastic response.

TS Ballot 1 Item #2 and Item #3 One negative on Item #2 and two negatives on Item #3.

Task Force 16-A: Review the options available and write a procedure for checking TFO/PAV pans for excessive warping. Members: Delaware (Karl Zipf), Asphalt Institute (Mike Anderson), and AMRL (Maria Knake)

Task Force 16-B: To review the precision statement for T240, review the ASTM method and more recent AMRL data. Members: AMRL (Maria Knake) and Virginia (Bill Bailey)

Volunteers to help were requested at the mid-year meeting.

Task Force 16-C: Review contradictory statements in Section 12.1 and X1.8.1 regarding the linear region in T315 and consider revision to current guidance in standard. Members: Asphalt Institute (Mike Anderson), Virginia (Bill Bailey), Nevada (Charlie Pan), John DAngelo (Consultant), Kathy Sokol.

Task Force 17-A: Precision and bias for T 350. Members: Joe DeVol (WA) will lead the effort. Matthew Corrigan (FHWA), Bob Horan (Asphalt Institute), John Malusky (AASHTO re:source), Lyndi Blackburn (AL).

Email report from Joe DeVol: Mike, Bob and I had a phone conference in early June in which we reviewed the results of all five Interlaboratory Studies that have been conducted to date. From these results, we are proposing use of three, the NEAUPG (2010), NEUAPG (2012) and the PCCAS (2013) to establish precision and bias statements for AASHTO T 350. While each of these ILS have merit, we chose the three studies based on the date, number of participating labs and the number and grade of binders tested.

The plan at this point would be to establish a precision and bias for T 350 based on an average to the three ILS. If any of you have any suggestions or concerns with the approach, please let me know and we will consider them before moving forward with the plan as stated.
