(2013 TS4a annual meeting sign-up sheets are Attachment 1).

3. Approval of 2012 minutes (Attachment 2).

- Minutes were reviewed during the session.

- Task force set up to help resolve NC’s negative for M 206 (TF 2013-01). NC DOT and ACPA

will be part of this task force.

- In the TS 4g webinar, it was decided to create an AASHTO standard for ASTM A 1064. This

standard will be put out for ballot in TS 4g. TS 4a will not look at A 1064, knowing we will have

an AASHTO specification in the near future.

- Action Item: A survey will be put together and sent out to see if states are using M 279 and M

253.

- Motion to approve minutes- AL DOT, 2nd

LA DOTD. TN DOT and OK DOT will be included in

the attendance record for the webinar that took place in Spring, 2013.

4. Resolve comments from the 2012 SOM Letter Ballot and Technical Section Ballot (N/A this year).

- We didn’t have any balloted items from last year- therefore we don’t have anything to discuss for

this item.

5. Discuss 2013 Technical Section Ballot (Attachment 3).

TS4a members- please be sure to turn in ballot votes as timely as possible in the future.

8. New Business:

A. Discussion Topics

“Friends” of TS 4a

- Each industry will have a singular representative.

- These friends will be included in the TS roster and they will receive ballots

Mid-year Webinar (April/May)

- Positive feedback was discussed about the webinar that was conducted in Spring 2013.

Research Liaison

- This person will coordinate with a task force that will be put together to submit research

ideas to NCHRP. This will be coordinated with the RAC members as well. Rick Kreider

will be the Research Liaison for TS 4a.

B. NCHRP Issues/Proposals

Are there any NCHRP, international or domestic scanning tours, or other proposals? We need

proposals to Jack Springer by Thursday afternoon.

NCHRP 20-07/Task 347: Test Methods to Determine the Hydraulic Performance of Culvert

Joints

The objective of this research is to develop recommended test methods for joint leakage (i.e.,

watertightness) in AASHTO standard format. The test method should consider the AASHTO

Standard Practice for Pipe Joint Selection for Highway culvert and Storm Drains –AASHTO

Designation: PP63-09.

- The contract is waiting to be signed for this research to begin.

VDOT submittal: CANDE Upgrade for 2014

- This proposal will be taken to Thursday’s meeting to review. The TS supports the proposal.

C. Correspondence, Calls, Meetings, Presentations by Industry

Interaction between NTPEP and industry pertaining to the potential prequalification of concrete

pipe plants through NTPEP. A draft copy of the proposed standard was provided for review by

the Tech Section. Comments were to be sent to Danny Lane (TN).

Comments by Katheryn Malusky and Danny Lane.

ACPA asked to address the Tech Section concerning this proposed Standard Practice.

- 45 minutes of discussion occurred surrounding the early draft of the standard practice.

From that discussion, two additional Task Forces were created (TF 2013-02 and TF 2013-

03), which are defined under “8.H. Additional Items”.

D. SOM Ballot Items (including any ASTM changes)

The following standards were discussed and will be advanced for the 2013 Subcommittee on

Materials Concurrent Ballot to address proposed changes to the equivalent ASTM standards

and/or proposed changes by task force members.


of 20

M 170 (C 76-13a) Reinforced Concrete Culvert, Storm Drain and Sewer Pipe

Current Version:

6.2.4.7. A combination of portland cement, ground granulated blast-furnace slag (not to exceed 25 percent

of the total cementitious weight) and fly ash (not to exceed 25 percent of the total cementitious weight).

Proposed Version:

6.2.4.7 A combination of portland cement, ground granulated blast-furnace slag, and fly ash.

Chair’s Commentary: During recent discussions at the annual meetings and teleconferences, there has

been a question raised concerning the need for the fly ash upper limit. Optimum fly ash quantity is mix

dependent; attaching a maximum percent is counter-productive.

Current Version:

6.2.4.8. A combination of portland pozzolan cement and fly ash, provided the fly ash added does not

exceed 25 percent by weight of the portland pozzolan cement.

Proposed Version:

6.2.4.8 A combination of portland pozzolan cement and fly ash.


been a question raised concerning the need for the fly ash upper limit. Proper testing is necessary to

define an optimum quantity. Attaching a maximum percent to fly ash use is counter-productive.

Current Version:

10.2.1. Steam Curing—Pipe may be placed in a curing chamber, free of outside drafts, and cured in a

moist atmosphere maintained by the injection of steam for such time and such temperature as may be

needed to enable the pipe to meet the strength requirements. The curing chamber shall be so constructed

as to allow full circulation of steam around the entire pipe.

Proposed Version:

10.2.1. Steam Curing—Pipe shall be placed in a curing chamber, free of outside drafts, and cured in a

moist atmosphere maintained by the injection of live steam for such time and such temperature as needed

to enable the pipe to meet the strength requirements. At no time shall the ambient temperature exceed

160°F. The curing chamber shall be so constructed as to allow full circulation around the inside and

outside of the pipe.

Current Version:

11.3.1. The load to produce a 0.01-in. crack or the ultimate load, as determined by the three-edge-bearing

method as described in T 280, shall be not less than that prescribed in Tables 1 to 5 for each respective

class of pipe. Pipe that support the prescribed load to produce the 0.01-in. crack and do not show a wider

crack shall be considered to have met the test requirement. It is not a requirement of this specification that

the pipe be cracked or loaded to failure during these tests. Pipe that have been tested only to the formation

of a 0.01-in. crack and that meet the 0.01-in. crack or lesser crack load requirements shall be accepted for

use. Three-edge-bearing test to ultimate load is not required for any class of pipe 60 in. or less in diameter

listed in Tables 1 to 5 provided all other requirements of this specification are met.

Proposed Version:

11.3.1 The load to produce a 0.01-in. crack or the ultimate load, as determined by the three-edge-bearing

method as described in T 280, shall be not less than that prescribed in Tables 1 to 5 for each respective

class of pipe. Pipe that support the prescribed load to produce the 0.01-in. crack and do not show a wider

crack shall be considered to have met the test requirement for D-load to produce a 0.01-in. crack. Pipe

that support the prescribed ultimate load without failure shall be considered to have met the test

requirement for ultimate load. It is not a requirement of this specification that the pipe be cracked or

loaded to failure during these tests.


of 20

Also add immediately after Note 3:

Note 4 – With the approval of the specifying agency, and with at least one annual proof-of- design test to

ultimate load for the designated pipe size and class, pipe with diameters of 60-in. or less may be accepted

without performing the three-edge bearing test to ultimate load provided all other requirements of this

specification are met.

Chair’s Commentary: This section was rewritten by a task force due to a request by a DOT for better

clarification. This represents a second balloting attempt to get satisfactory wording.

Current Version:

11.9. Absorption—The absorption of a sample from the wall of the pipe, as determined in accordance

with T 280, shall not exceed 9 percent of the dry mass. Each sample shall have a minimum mass of 1.0

kg, shall be free of visible cracks, and shall represent the full wall thickness of the pipe. When the initial

absorption sample from a pipe fails to conform to this specification, the absorption test shall be made on

another sample from the same pipe and the results of the retest shall be substituted for the original test

results.

Proposed Version:

11.9 Absorption—At least once a year, determine the absorption according to T 280. The absorption of a

sample from the wall of the pipe shall not exceed 9 percent of the dry mass. Each sample shall have a

minimum mass of 1.0 kg, shall be free of visible cracks, and shall represent the full wall thickness of the

pipe. When the initial absorption sample from a pipe fails to conform to this specification, the absorption

test shall be made on another sample from the same pipe and the results of the retest shall be substituted

for the original test results

H. Additional Items

- Rick Kreider’s position has changed within KDOT. He is no longer over the Materials section. He is

not sure how much longer he will be able to attend this meeting. He would like to see if someone

would step up and be the chairman of TS 4a.

- ACPA would like to submit some changes for M 170 regarding absorption testing. Testing would

need to be completed at least once a year.

Two Task Forces were created due to the discussion over the proposed Standard Practice for Precast

Concrete Products.

- TF 2013-02- Inspection of Precast Concrete Products. Taking the standard practice for

verification activities. Have a standard to include QMS requirements. This standard will include

the tools for inspection. Members: AK, FL, WV, NC, LA, ACPA, NPCA, PCI. Tim Rulke (FL)

will be the lead of this task force.

- TF 2013-03- Auditing the auditor- FHWA (Tim Aschenbrener), Kim Spahn (ACPA), Curt

Turgeon (MN), Darren Hazlett (TX), and Rick Kreider will chair this task force. This task force

should be supported by TS 5c. [NOTE: In addition, Phil Cutler (NPCA) and a yet unknown

PCI representative will also participate on the task force.]

3. Approval of 2011 minutes (Attachment 1).

TS 4a Comments: Moved (SC), 2nd (TN), passed.

4. Resolve comments from the 2011 SOM Letter Ballot and Technical Section Ballot (Attachment

2). Chair was attempting to align AASHTO specs with ASTM, with help from ACPA. Due to the number of negatives,

the Chair elected to not adopt certain changes to the specifications. The negatives were consistent for Items 51, 52,

53, and 54. The Chair received a Motion of Support for this decision. Moved-NC, 2nd-

SC.

No comments when the group was asked for suggestions on moving forward from the previous year’s negatives.

ITEM 51 – Concurrent Ballot M 170.

Concurrent Ballot: Affirmative 44/52 votes. Negative 5/52 votes. No 3/52 votes. TS 4a Comments: OK will give suggested language for section 11.3.1. VA suggests that the language for absorption in 11.9 is too

liberal and needs to be tightened. VA also requests language that gives the states more options for additional testing.

Section 11.2 will remain as currently written. These comments will be the same for items 52, 53, and 54.

OK has given suggested language and New Jersey and the ACPA will review for acceptance.

VA negative due to number of absorption tests per year (1), proposed language is “Not less than one per year.”

MI and NC negatives withdrawn.

ITEM 52 – Concurrent Ballot M 170M.

Concurrent Ballot: Affirmative 44/52 votes. Negative 5/52 votes. No 3/52 votes. TS 4a Comments: 6.2.4.7-VA concerned why fly ash was limited. Task Force 12-02 will be created to review the fly ash restriction

and provide recommendations to the Tech Section.

ITEM 53 – Concurrent Ballot M 206M/M 206.

Concurrent Ballot: Affirmative 45/52 votes. Negative 4/52 votes. No 3/52 votes. TS 4a Comments: See comments above.

NC negative – sections 8.1.3.1 and 8.1.3.2 – NC believes the concrete cover was reduced too much, especially at the

spigot. ACPA was trying to make it consistent with circular pipe. Apparently, oval pipe is difficult to comply with

this requirement.


Concurrent Ballot: Affirmative 45/52 votes. Negative 4/52 votes. No 3/52 votes. TS 4a Comments: See Comments above.


Concurrent Ballot: Affirmative 46/52 votes. Negative 3/52 votes. No 3/52 votes. TS 4a Comments: Task Force 12-02 was created to address some of the negatives.

5. Discuss 2012 Technical Section Ballot (Attachment 3).

Reconfirmation of Standards

M 176M/M 176-07, Standard Specification for Porous Concrete Pipe

M 178M/M 178-07, Standard Specification for Concrete Drain Pipe TS 4a Comments: Chair discussed the tech section ballots that were initiated prior to the meeting.

M 176M and M 178M will be reconfirmed in 2012.
