3) Approval of Minutes
ON MOTION (Eichman/Briggs) the minutes of the last meeting were approved as corrected.
Motion passed.
4) Selection of Chair – Kelly Briggs volunteered to serve as Chair of the committee.
ON MOTION (Rockers/Eichman) Kelly Briggs was selected to serve as Chair.
5) Quality & Soundness Testing – Josh updated the committee on testing. At the time of our planned
February meeting date, KDOT had 89 aggregate samples, 57 completed, 5 were waiting. We had 22
production samples 11 waiting, 48 have been official quality. KDOT is caught with testing. Josh
then reviewed the estimated computed dates on the freeze/thaw testing. The committee discussed and
reviewed the handout with KDOT. KDOT is working towards plotting curves on these samples.
KDOT advised if you have two passing tests you are on the list. KDOT is starting fresh with testing
samples. Blind samples – There is not much to update. KDOT is still doing blind samples however;
they have been too busy with 660 that they have not done many samples. It was asked that KDOT
provide the results of the blind testing. KDOT advised that 17 personnel changes took place in the
lab through all these budget cuts. MRC lab – KDOT is backlogged. Are there any new sources that
requested testing? KDOT has received a few but not many.
6) Use & Application of Aggregate Base – At this time, there was no new information.
7) Changes to Specifications and Part V – A member had asked KDOT about changing the percentage
passing from 2.0% to 2.5%. KDOT did some research and found that according to the CMS testing:
at the 2.5% limit, 11 percent failed and then at the 2% limit, 19 failed. As there are fewer sites to
provide materials, there are more transportation costs so maybe we should return to the 2.5% limit.
CMS requires the percent retained but doesn’t require any other information. However, if we return
to the 2.5% then KDOT needs to enforce it.
8) D-Cracking Study – Rick advised that they do have the new specification 660 in full
implementation, however noted that there are new changes that need to be addressed in the Part V.
Rick advised that the changes made in Part V will be substantial. KDOT will continue to work with
KRMCA to do come up with a better plan on ensuring quality. The committee discussed the quarry
monitoring program. Quarry monitoring course is a priority; and they hope to do a course soon.
OGCA (On Grade Concrete Aggregates) is the KDOT official name of the 660 specification. The
committee discussed the research that Kyle Riding, KSU is performing on KTMR-22. Some of his
research will tie into Phase II. KDOT hopes to have it available soon, maybe the next meeting.
9) Construction Samples – Communication – Samples being taken at the job site. At the quarry, you
deal with the quarry monitor, then at project, you are working with the construction inspector. The
construction inspector who is reviewing process and should maintain communications though the
process. Can we have a quarry monitor on the site when we take production samples on the new
specification? KDOT would like that; however, their resources are limited. The committee discussed
the inconsistencies between the quarry monitors, construction inspectors, and district offices.
10) Other Business - Wendy advised that members have visited with her to see if there was industry and
KDOT interest in hosting the KDOT/Industry partnering seminars. KDOT and industry thought it
would be very beneficial as it has been two years since we have held these seminars. Wendy will
work with KDOT on setting up a planning meeting in June.
11) Next Meeting Date – Wendy will work with the chairs and KDOT on the next meeting date.
12) Adjournment - ON MOTION (Rockers/Eichman) with no further business to come before the
committee, the meeting was adjourned at 2:24 p.m. Motion passed.
