This needs to be restored ASAP if it can.
Now you put something called air entrainment into concrete. It drastically reduces the freeze/thaw damage to concrete. That chemical didn't exist back when the early sections were placed. There might possibly be some coatings that could be used to slow down further deterioration, but you're not going to restore it. Restore means to make it like it used to be. For that to be the case, a plaster cast would have to exist for you to use to mimic the old one and build a new one.

Now that I think about it, 3d surveys of buildings are now not that uncommon. I bet that they could make a point cloud of these, then have some one do adjustments in the computer to try and mimic what they used to look like compared to old photos and then send that output to a 3d printer. They then pour concrete with the 3d printout placed in the form as a void. That might actually work. It dang sure wouldn't be cheap.

A co-worker works with the person quoted in the article. I just sent my idea to him so he can forward it to Brandon and I also copied a professor I know in the Civil Engineering Department. This could be an interesting school project.

those things are pretty cool, but they are very expensive

There might be a little bit of money laying around the athletic department.... :)

I thought years ago a mold could be made of the prints and then transferred to another slab.
But then you'd have a copy of something in bad shape. This might be able to yield a result looking like the original. The faculty member I sent it to has forwarded it to colleagues that specialize in this sort of thing.
