Sound like something on the menu at your local
pub?

That's what comes to my mind every time I see these
signs along the roads here in the Pittsburgh countryside.
Maybe pita chips and seasoned olive oil?

No, it's a weird local (as far as I know) phenomenon
where in the summer many of the back roads sport these
signs. It means the county (or whoever is in charge of
these roads) is going to put gravel chips and oil on the
roads. I guess it's supposed to do something to keep
them in good repair, but I've always found it odd.

It would make sense on dirt roads, and in fact it is done
on dirt roads also - at least the oil - but this is done
on asphalt roads. Huh? What is that about?

Anyway, the signs have sprouted, warning motorists of the
coming attraction. Some roads have already been done.

I don't know why, but those signs make me hungry.

Maybe I'll invent a new Pittsburgh snack called "Oil and
Chips". Wonder how it will go over?

It is also great for pitting your windshield and often making nice
"stars" in them as well. After a seal-coating, I met a car while my
window was open...a nice sharp pointed rock chip ricocheted around the
cab of my truck but fortunately missed me. The bonding asphalt was too
light and not tacky enough in my estimation.

You have to wonder!!!

Oil on asphalt would turn them into skate rinks with the addition of a bit of
water!!

It's called chip and seal or chipseal. Not seal-coating. I'm not
going to google more but I think some roads are never actually paved
but made by the chipseal process.

They seem to have abandoned that method in my state. Now they seal the
cracks only. They have a large trailer mounted tank filled with the
sealant and there is a hose and wand that the operator uses. I suspect
this uses a lot less material and you aren't dinging windshields and
blasting the paint off cars.

All it takes is a bucket of kerosene or diesel and a stiff wire brush.
