Better, Concrete spalls from pressure of rusting rebar asphalt don't have rebar. Other side of the line, asphalt bubbles when brine seeps into joint between layers due to poor laying job and snow plow shaves bubbles off.
Asphalt is plastic, concrete is solid so asphalt moves from tire wear. Also suffers UV light damage. Biggest problem is LOW BIDDER. Asphalt only good to lay in temperature range but low bidder don't check temperature or reject cold load. You see it year or so later. Lazer on layer screws up you see after first rain. Inspector already spent bribe so nobody cares.
Concrete pothole can be cut out, pinned and repoured, but rarely gets done.
Salt only a problem if brine reaches rebar. See it a lot on bridge decks. Proper concrete placement solves problem most times. LOW BIDDER creates problem most times. Bridges get built to be rebuilt & create jobs for Laborers. Laborer Union good political contributor. Taxpayer bottomless pocket. Truck road tax bottomless pit. 120 day job to replace bridge deck wid jackhammers, 80 days wid machine from Canada. Guess how dat job gets bid.
1980s CAT built mile long machine, chews top layer off superslab, runs old stone thru heater den into mixer, followed by Pavement heater den into layer followed by fleet of rollers. Hour after shaving brand new surface and if job done right, properly stuck to base. System fell out of favor fast, eliminated Union jobs. Probably went to China by now to come back as paperclip.
Might have something to do with the owners pass on last year and year before....
Curiously, how do they compare in sharpening up the state of ME snow plow cutting edge?

LoL...Obviously "some" peeps have never read or seen a state or federal DOT (paving) contract or the included specifications...OR worked with a winning bidder on said contracts and with the required on site state or federal inspectors etc... because they obviously have no clue what they're talking about...!

When Rieth & Riley paved that section, they put a new guy on the concrete paver for a day. They had stout cord stretched between stakes every so many feet that was set to the grade for the paver to follow. Obviously, the cord would sag between the stakes, but the machine had a setting to adjust for the sag. However, the new operator didn't know about it and didn't turn it on, thus, the machine followed the sagging cord for around a mile before the regular operator was back on the machine.
When the DOT saw the dips, they wanted R & R to tear up the whole mile and replace it, but R & R talked them into letting them mill it down to remove most of the unevenness. It helped, but it is still very noticeable, especially in a big truck. I believe that it was milled again a few years back, but it's still like a roller coaster.
I wasn't aware of that.
I wondered about that. Every paving job that I see has a DOT inspector with his little testing machine to ensure the right density and ? I don't believe they are allowed to pave unless the inspector is on site.
