Restructured:
Consolidated some existing TS
Created a new TS (Bridge and Pavement Preservation)
19 Technical Sections, EC, ATG
The 19 Technical Sections cover all materials used in transportation projects from asphalt to pipes, organized into five Divisions: (1) Geotechnical; (2) Asphalt Materials and Mixtures; (3) Hydraulic Cements, Concrete, and Concrete-Related Materials; (4) General Manufactured Materials; and (5) Pavement Serviceability, Environmental Quality and Quality Assurance
Technical sections are established to write and maintain standards in specific areas within the scope of the SOM. The technical sections are responsible for initiating standards for the balloting process.
The technical section chair may organize the technical section into task groups to work on a particular standard or group of standards or assign responsibility for maintenance of a standard to individual technical section members.

6. SOM + JTCOP = COMP COMP Reorganization
Subcommittee on Materials and Joint Technical Committee on Pavements have merged to create Committee on Material & Pavements
SOM + JTCOP = COMP
Each state / agency will have one voting member, and up to three total members
The SOM is currently one of nine subcommittees of the Standing Committee on Highways (SCOH). However based on the recent reorganization proposed and approved, SOM will be merged with the Joint Technical Committee on Pavements. The newly merged committee will hold its first co-located meeting in Cincinnati in August 2018.

7. Annual Meeting
The tech sections rely on members – materials engineers from the state DOTs – to provide their input and expertise in order to develop, revise, and update standards. It is vital for the states to participate, both in the mid-year webinars as well as the Annual Meeting – in order to help drive research forward and manage/control the development of new standards. The Annual Meeting spans 5 days of intensive meetings to discuss items for development of the next year’s standards volume, discuss research, and transfer of information between states as well as with federal highways. With regard to research there is a Research Task Force to help select research proposals from the individual meetings and then prioritize them.

If interested, contact Derek Nener-Plante
The designation “Friend of the committee” pertain to individuals from Industry, Trade Associations, and Academia, as well as ASTM. Friends do not have voting rights but do have the opportunity to review the ballots and provide feedback.

9. Balloting
With regard to the ballot, following the annual meeting all revised and/or new standards are to be uploaded to the SOM Library in September by the stewards or tech chairs. The SOM Secretary prepares the Fall Ballots, which are issued as a rolling ballot in three groups (Group 1: TS3’s,5’s, and re:source ; Group 2: TS4’s ; Group 3: TS1’s & 2’s) in September, October, and November respectively. On average there are over 100 total ballot items each year, and develop approximately 10 new standards in that timeframe as well.
Reconfirmation ballots are sent out at the same time; these are handled by AASHTO on behalf of the TS chairs.

10. Mid Year Webinars
Scheduled November – February (according to release group)
Provide an opportunity to discuss and resolve any remaining issues and start the process for the next ballot cycle
Maximizes time at annual meeting sessions

11. Why?
Number of standards did not fit into the mission of the major technical subcommittees:
TS 1C: Aggregate Materials
TS 2A: Emulsified Materials
TS 2B: Asphalt-Aggregate Mixtures
TS 2D: Proportioning of Asphalt–Aggregate Mixtures
TS 4C: Markings and Coatings
Preservation are often systems that cannot be divided into separate components
Preservation gaining traction

12. Technical Subcommittee 5B: Bridge and Pavement Preservation
New technical subcommittee created in Fall of 2016
“This technical section will promote and publish standards relating to bridge and pavement preservation not sufficiently covered in other technical sections (i.e. bridge paint is covered in TS 4c). The technical section will be responsible for related standards which could include but are not limited to chip seals, crack seals, micro-surfacing, high-friction surface treatment, concrete sealers, etc.”

13. Technical Section 5B Leadership
Chair: Derek Nener-Plante, MaineDOT
Vice-Chair: Travis Walbeck, West Virginia DOT
Secretary: Morgan Kessler, FHWA
AASHTO Liaisons: John Malusky / Casey Soneira

15. How does this impact you?
Get involved with your COMP representatives
Comment on proposed standards – they can get your feedback
Use the new standards in your specifications
Start out as provisional – need to show they are used so that they can be approved to full standard
Provisional standards must either be fully accepted or they lose approval after 8 years
Stay tuned on the construction specifications

16. What about the construction specifications?
COMP has never handled construction specifications
Committee on Construction (COC) has published guide specifications, but only at a frequency of years
Committee on Maintenance (COM) resolved to take over preservation specifications, but do not have the infrastructure to do so

17. NOW, THEREFORE, BE IT RESOLVED, That the AASHTO Highways Committee on Maintenance recommends to the Highways and Streets Council of the AASHTO Transportation Policy Forum to assign to the Committee on Materials and Pavements, Technical Subcommittee 5b, for a five year period, the responsibility for reviewing, maintaining, and publishing pavement preservation materials standards and pavement preservation treatment construction guidance specifications to the corresponding publications (e.g. AASHTO Materials Book or AASHTO Construction Guide); and that the COMP Technical Subcommittee 5b add 3 to 5 voting representatives from each of the Committees on Maintenance and Construction for the development and review of preservation construction guidance specifications.

18. Construction Guide Specs - What’s next?
Resolution was proposed and voted on at the Spring AASHTO meeting - PASSED
The implementation will start immediately
Technical subcommittee 5B will receive and review construction guide specifications starting in summer of 2018

19. How will they be published?
Those documents that are materials specific standards, utilized for materials acceptance, shall be published in the AASHTO Materials Book.
Those documents that are construction specifications, written into construction contracts, shall be published in the AASHTO Construction Guide.
