General

  1. States provide names to Ben/Lisa related to NRRA travel to TRB in 2018
  2. NRRA meeting (open to everyone) – Thursday January 11th from 8-12

Flexible Team Notes

  1. Short Term Research
  2. SRF will be setting up meetings with the TAP for the short term research (Tack Coats, Longitudinal Joints) in the upcoming month. TAP members should review the current online documents on the team page. Most of the pulling together information is done – the NRRA TAP members will be asked now what do we want to do with it.
  3. Long Term Research
  4. Expect both contracts to be finalized in November – Discuss at the Dec meeting.
  5. PM Team will be sharing some thoughts on PM work on the test cells at MnROAD including a plan/mini study looking at sealing reflective cracks on the HMA over PCC cells.
  6. HMA Performance Testing of MnROAD samples.
  7. Dave Van Deusen will
  8. Communicate what agencies are doing what tests, which includes the number of buckets of mix that is needed. Amount of buckets will be prioritized by NRRA contracts, NRRA members, and tests that are being performed.
  9. Share the mix design details from 2017 MnROAD.
  10. Members will
  11. Share the testing protocols they use, which should include aging protocols and test temperatures.
  12. Share the contact and address the buckets should be shipped to. NRRA members no cost for shipping.

Rigid Team Notes

  1. Short term Research
  2. Team prioritized the Design and Performance of Concrete Unbonded Overlays over the repair of Joint Associated Distress for the consultant to focus on first.
  3. Members will
  4. TAP members review and update the problem statements online before the next meeting so the contract will be properly directed for what we want.
  5. Design and Performance of Concrete Unbonded Overlays (Lead – Maria – Link is to the team page)
  6. Repair of Joint Associated Distress (We don’t have a lead listed – Brett can you assign this to someone? – Link is to the team page)
  7. Provide specs on both topics for the NRRA web page to be posted and used by SRF Consultant – send to Ben/Bob F for Web posting. Right now nothing posted.
  8. Design and Performance of Concrete Unbonded Overlays will also need performance trends. Once the project starts the states are going to have to develop a common method to report on the performance. Maybe a survey on do they build them, pros/cons, # jobs/year, # years have been doing, key reports, key people.
  9. Long Term Research
  10. Expect both contracts to be finalized in November – Discuss at the Dec meeting.
  11. PM Team is interested in the rigid teams thoughts / will be sharing some thoughts on PM work that can be done on the test cells at MnROAD.

Geotechnical Team Notes

  2. Team prioritized the Subgrade Design for New and Reconstructed Subgrades over the Larger Subbase Materials for the consultant to focus on first.
  3. Members will
  4. TAP members review and update the problem statements online before the next meeting so the contract will be properly directed for what we want.
  5. Subgrade Design for New and Reconstructed Subgrades (Terry Beaudry (MN) is the lead – needs some work – Link is to the team page)

Preventive Maintenance Team Notes

  1. Short term Research
  2. Team prioritized the Surface characteristics of diamond ground PCC surfaces and Pavement preservation approaches for lightly surfaced roadways for the consultant to focus on first.
  3. Members will

Example – should the HMA overlay of PCC be sealed or not, or seal half in a cell and leave the other half, …. Jerry and Ben will work to develop an initial thoughts and share with the team for discussion at future meetings. Nugget – one crack has already reflected though after 1 month and a couple cool fall days.

  2. TRB
  3. Discussed the TRB suggestion to a one pager for NRRA members at TRB. MnDOT will develop a draft to share at the December meetings
