What's with the little road cuts?

Roadconstructionfilter: Why do I see so many highway crews replacing only a 10' by 2' section?

It seems like they cut a section only wide enough to get a hammer drill and drill rebar holess into the unmolested part, then pour it back in with concrete. Then the make another cut 20' down the road!
Is this for research purposes - to see how various roadbed recipes hold up, or something else? Why not replace a whole section if there's a problem - I imagine the labor costs on a small cut are much more than the concrete to do, say, a 10'by 30' section?
