Looks good. The only area I see some potential pushback is that the idea of sawcutting the steel on either side of the joint. That idea will be a surprise to them. I have not previously
spoken to Lyn about that. It’s something I researched after we spoke.
The other thing is that the FAA doesn’t have JRCP design, but TxDOT does. TxDOT’s design procedure will be fine if they choose to go that route. Hopefully, they’ll choose to cut the
steel. It’s the easiest and most reliable way to control the cracks.

Lynn,
The Town of Addison has reviewed the attached jointing plan and takes no exception to the dowel bars being limited to the areas indicated. However in a meeting with the developer and
his architect this morning, they have expressed interest in paving the area out to the taxiway. In this instance the dowel bars would be required along the taxiway.
On another note, the joint plan as laid out appears to be a Jointed Reinforced Concrete Pavement (JRCP). There is a design method that should be used to determine the reinforcing size,
spacing and joint spacing all of which are interrelated (i.e. the amount of steel affects the joint spacing and vice versa). Submit the JRCP design in accordance with the FAA Circulars
with the next submittal. Alternatively, specify that the reinforcing steel it to be cut 3” from either side of each sawcut joint. Under the alternative method the concrete is no longer
continually reinforced and the JRCP design procedure is not necessary.
If you have any additional questions, please let me know.
Thanks,
Clay Barnett, P.E.

Todd,
Attached is a copy of the ramp jointing plan with clouds shown where I believe the doweled joints should be located. As I mentioned, the other edges will not have the loading on them
since the aircraft only park in these areas and the weight of the aircraft does not get close to the edges.
Please review and let me know what you think.
