True dat! I've never seen a road crew out sealing an entire asphalt highway.
No highways but I've seen them doing plenty of Mall parking lots including our local Walmart.
Residential streets, too. They call it "seal coat". Maybe it's a different thing, but with what I'm thinking of they spray a liquid asphalt on the street and then pour some small gravel on it so that traffic can be on it again. A few months later they sweep up whatever gravel is loose.
