Nancy, Here’s a recap of my discussion with Mr. Kadleck in regards to my review of their plans. I spoke to him this afternoon, 12/20/10. In the review, I asked them to place dowel bars within 20’ of a free edge. He doesn’t want to that because airplanes won’t be parked within 20’ of the edge on parts of the apron. The FAA Advisory Circulars don’t have an exception in that case, but I believe it does assume that every part of airfield pavement should be designed to carry aircraft load. We compromised and he will submit the areas he is proposing to include dowels. If you have a set of his plans, look at Sheet 7. I performed my review treating the details on that sheet as what was intended to be used on the ramp only. They don’t show reinforcing going through the sawcut joints. In our conversation, he told me that their intent was to allow the steel to go through the sawcut joints. That could change the joint plan so after our conversation I did research and spoke with some of our senior pavement engineers. Here’s the consensus: The joint plan as laid out is 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. The solution that I have been using cases similar to this is to have the contractor cut the reinforcing steel 3” from either side of each sawcut joint. This will allow them to avoid the JRCP design procedure. I’ve successfully done this in the past and have gotten little pushback from the contractors I’ve asked to do this. Unless he has performed the JRCP design, I’d recommend this instead. I can continue to talk to Mr. Kadleck about this, or I can go through you or Clay. I want to streamline the process, but also want to make sure the proper channels are followed. Let me know if you want me to stop going directly to Mr. Kadleck. As always, call with any questions.
