Mike,
Attached are some calculations for the pavement steel for Freeport. Based on our calculations the #3 bars provide sufficient reinforcement.
However, I noticed that City details do not provide tie bars at longitudinal joints and no dowel bars at contraction joints. This is probably OK since the joint spacing is relatively
short at 20 feet – but it would lead me to be conservative on the temperature steel and increase the requirement from #3’s to #4’ as noted in the current standard detail. Perhaps this
was the reason that the detail was amended?
As for the contract documents, I understand CD Builders position regarding the timing of the construction documents. Based on our experience with them to this point, I’d like to think
that they would have provided #4’s in lieu of #3’s had it been discussed prior to installation of the current pavement sections.
Again, per our analysis it appears that the pavement sections currently installed with #3 bars contain sufficient steel reinforcement per industry standard design guidelines.
Please let me know if you have any additional questions or would like to discuss this issue further.
Thanks
Chris
