Four tests, about five minutes, and you can do all of them without tools. Do them in April, once the salt has washed off and before the season opens. That is when an Akron driveway tells you the truth about the winter it just had.
If your drive runs on a grade, and a great many in Summit County do, the low end has been standing in meltwater every thaw for years. It is routinely a season or two ahead of the top in wear, and it is the end that decides whether the drive needs doing.
Walk the apron first, where the drive meets the road. That is where a plow blade catches, where salt spray off the street lands heaviest, and where the surface starts letting go first. If the apron is sound the rest usually is. If it is loose underfoot, what the middle looks like matters much less than you would think.
Tip a bucket of water across the surface and watch it for ten seconds. On a sealed, sound driveway it beads and runs off. On a driveway that needs doing it goes dark and soaks straight in.
Water getting into asphalt is the failure mechanism. It freezes, expands about nine percent, and levers open whatever it got into, over and over from November into April. A surface that drinks water here is on a short clock.
Do the test at the bottom of the slope and again near the garage. A drive that beads at the top and drinks at the bottom is a normal Akron result and it still needs doing.
Look for a pale, chalky film that keeps coming back after rain washes it off. That is salt residue sitting in a surface porous enough to hold it, and it is close to an Akron-only reading. Driveways in parts of Ohio that see a dozen inches of snow a year do not do this.
A bloom that rinses away and stays away is just this winter's salt. A bloom that returns every time the drive dries is telling you the surface has opened up enough to take the chloride in and hold it, and chloride works on the binder holding the stone together. That is a surface with no protection left on it.
Press your palm flat on the surface and drag it a foot. If loose grit comes away, the binder has gone and the stone is no longer being held. That is raveling, and it is the stage where sealing still helps. Wait another two winters and it is not.
Check the wheel tracks and the turning spot separately from the middle. Those wear first because they take the traffic, and on a graded drive the tyres work hardest exactly where the water collects.
What matters is width and pattern, not how many.
Hairline surface checking, fine lines you could not lay a pencil in, is the surface drying out. Sealing addresses it.
Single cracks you can get a pencil into are filled first and quoted separately, and in this market there are usually more of them than the owner expects, for the salt reasons above.
Interconnected cracking that looks like crocodile skin is the base failing underneath. That is repair work, not sealing, and it is the common ending here because enough winters of water getting underneath is exactly what kills a base. A coat over it buys you until about February.
Still deep black including at the apron, water beading, no loose grit, sealed since last spring. Leave it. A coat now buys you very little and you can spend the money in two years when it will do something.
Also no if it is new asphalt. It has to cure first, commonly six to twelve months, and sealing early traps oils still working their way out.
And no if it is crocodile cracking or a soft patch at the bottom of the slope. That is a repair, and anyone who offers to seal it instead is selling you a year.
Two to three years on a residential drive here, which is the short end of the range you will read on a national site, and it should be. Those ranges are averaged across a country where most driveways do not take four months of freeze and salt.
Sealing on a fixed calendar is the wrong instinct in both directions. Run the water test each April. It answers the question for your driveway, which is the only one that matters, and it costs a bucket of water.
A lot of Summit County housing went up in batches. A subdivision was laid out, and the driveways in it were poured or paved by the same contractor within a year or two of each other, off the same base, to the same depth.
That makes your neighbours a genuinely useful instrument. If three drives on your street have gone grey and are raveling at the apron, yours is on the same clock even if it currently looks better, and the difference between you and them is usually one coat somebody put down eight years ago. If everything around you still looks sound, your own bad patch is more likely to be drainage or a plow catching one spot than the surface reaching the end of its life.
It is not a substitute for the water test. It is the thing that tells you whether to expect the answer.
