Patching Concrete Airfields

[7515325]

Question to all. What is the best method for patching small (spalls) patches on an concrete airfield. Givin the area does not have to be open in a hurry no extream weather conditions just the best fix for patches 3" in depth with an average area of 2-4 sf. I have used epoxy with clean aggregates, high strength concrete, quick set materials and many other types of fixes. Just wanting some input. Any input would be appreciated.

I would use a high quality polymer modified concrete. Sika has several very good products as do some other manufacturers. Epoxies have higher expansion coefficient that can sometime be a bit of a problem with temperature extremes.
