Recommendations and Comments

KYTC D6	62 Robert Hill Agency	Y Approve	Seems to be a good assembly process. May want to consider a modification to Std. Drawings when applying these machine welds until more testing can be completed weighing A615 vs. A706. Is this for 9T wall only or all uses? Can they be epoxy coated?	May 22, 2009	264
KYTC D3	60 Greg Meredith Agency	Y Approve		Apr 27, 2009	258
KYTC D9	48 Phil Mauney Agency	Y Approve		Apr 27, 2009	254
Construction	77 Rachel Mills Agency	Y Approve		Apr 23, 2009	238
KYTC D5	76 dav kessinger Agency	U Undecided	The concept seems good, but… I looked into the southern exposure (SE) macrocell test performed in comparison between the A615 and A706 reinforcing steels. What I found from one report is that the A706, when exposed to a concrete environment, shows around 65% to 70% higher corrosion than A615. This would indicate that the unit or member being cast could require repair/maintenance much earlier than a similar member using A615 steel. If this was taken into account with the use in 9T wall, it would make since due to the wall being temporary. This would still have me concerned about the long term reuse of the same 9T wall on projects over the years.	Apr 23, 2009	237
Structural Design	130 James Miracle Agency	Y Approve	The attachments and test results suggest the steel can be shaped and/or straightened without degradation in its strength.	Apr 23, 2009	234
KYTC D8	66 Bruce Neely Agency	Y Approve	Looks to be of value in increase of production of certain steel reinforced structures and applications.	Apr 23, 2009	233
KYTC	32 David Quarles Agency	Y Approve	See the attachments to see this process is accepted for 9T barrier walls already. MMI wants to expand the product line. Testing was performed at the Div. of Materials in 4/09. Hoops (#4 plain deformed bars) were cut out of a cage and cold worked back to straight, a worst case scenario. These samples were tested in tensile, elongation, and bend and all passed. We will ask for Construction and Structural Design for their recommendations.	Apr 23, 2009	145
