Recommendations and Comments

KYTC	1207 Steve Spradlin Agency	U Undecided	I agree with Wendys comments that this currently does not meet our policy based on the "and be crash tested at an FHWA certified facility with a minimum of 0, 45, 75, and 90 degree impact angles." comment, BUT based on the vendor response to Wendy's comment & a discussion with Wendy I would agree that we may need to review our current policy to see if it's more stringent than is required by MASH and adjust accordingly. Wendys last comment about the speeds at which the test were conducted has not been clarified. I would be in favor of doing a test installation of this product.		Sep 27, 2022	3160
KYTC	903 Gary Newton Agency	U Undecided	We are in need of a MASH approved product for a Sign Breakaway System. This says it's MASH approved but, for one test only so, I agree with Wendy on this one. I would however like to see Traffic's take on this one.		Jun 02, 2022	3133
KyTC-Design	1108 Wendy Southworth Agency	U Undecided	According to the MASH testing that was completed for this product, the only angle that was tested was 0 degrees. According to our policy in order for a Breakaway sign post support to be on the approved list it must be tested at a minimum of 0, 45,75 and 90 degrees. (see below) BREAKAWAY SIGN POST SUPPORT SYSTEMS FOR TYPE C BEAMS To be placed on this approved list the material supplier or manufacturer must meet the following criteria: 1. Demonstrate Omni-Directional Breakaway Performance and be crash tested at an FHWA certified facility with a minimum of 0, 45, 75, and 90 degree impact angles. 2. Comply with NCHRP Report 350. 3. Comply with the AASHTO 2002 Roadside Design Guide. 4. Comply with the MUTCD 5. Comply with the KYTC Division of Traffic Operations Guidance Manual. 6. Comply with Section 106.04 of the Standard Specifications for Road and Bridge Construction Buy American Requirement. 7. Perform sufficient structurally to support the beams and signs and to resist ice and wind loads as specified in the 2001 AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals. 8. Require no specified torque on the bolts. 9. The supplier must be able to provide a parts inventory for future maintenance. I would say that additional MASH testing would be required in order to determine if this breakaway sign support can be utilized within the clear zone. And also the speeds at which the tests were conducted would need to be noted as well.	Thank you for the note. I spoke to the third party test facility we used in order to get an answer from a MASH expert. I am summarizing an email they sent below, and I would be more than willing to discuss further. MASH specifies testing of support structures be performed at a critical impact angle (CIA) between 0-25 degrees (ref. Section 2.2.4). MASH states that "The critical impact angle should represent the worst case impact condition that is consistent with the manner in which the test article will be deployed along the roadway." Due to the nature of how this system will be installed, 0 degrees was selected. MASH further states that support structures used near an intersection should also be evaluated at 90 degrees in addition to the CIA. In other words, the nature of the application and its direction of exposure to traffic is a determining factor in the impact performance of a support structure. MASH further states "Features that are designed to be used along the outside of divided highways need only be evaluated for impact angles of 0 to 25 degrees". This system is designed for use in this exact scenario. Finally, MASH notes that if a support structure is used in locations where it could be subjected to reverse-side impacts, both 0-25 and 155-180 degree impacts should be considered. One characteristic of the system is that it is not directionally dependent when impacted, so this should not be a concern. Systems that utilize a fuse plate could require both 0-25 and 155-180 degree impact testing. The concept of Critical Impact Angles (CIA) are new to MASH. Products tested to NCHRP 350 would have been tested to 0 degrees with only a handful additionally tested at 90 degrees for intersection evaluation. From the testing agency, they are not aware of any system being testing to the multiple angles as prescribed in the standard and would not be necessary to do so based on the MASH standards.

KYTC	313 Michael T. Black, P.E. Agency	U Undecided	Design seems innovative, but I will defer to Highway Design for final recommendation.		Apr 27, 2022	3114
KyTC Construction	1092 Matt Simpson Agency	U Undecided	I would defer to highway design and traffic.		Apr 26, 2022	3112
KYTC	528 Wesley Glass Agency	U Undecided	I will rely on Highway Design review as indicated on the LAM.		Mar 15, 2022	3081
