IS it something about the composition of the asphalt?

In NZ our high speed roads, and many low speed ones too, are surfaced with liquid tar, and then coated in small sharp stones. This adds a great deal of road noise and wear to the equation. We use much harder rubber than is used in the US, to prevent faster wear.

Why?

Cheaper; seamless; more elastic and tougher; more easily resurfaced; not prone to potholes; suits the terrain. There’s no perfect road surface, but you can choose the one that is optimal. Chipseal is great for windy highways. Hot mix asphalt is mainly used in build-up residential areas and on motorways. We don’t really use concrete for roads at all.
