7.5 years. LOL.

There was (is?) a system we (the UK) used to build roads which was
supposedly cheaper. As I recall, they put in the 'base layers' and then
a 'top coat' (or coats). The idea was, provided the top coats were
renewed every x years (x was quite small, I think 5-10 at most) the road
would last for ever.

Needless to say, the top coats weren't replaced in many cases, so the
base layers got damaged, and the whole idea flopped. Whether it would
have worked if applied correctly is open to debate.

Certainly, I can think of (main) roads that seemed never to need repair
but weren't made of tarmac - but they were darn noisy to drive on, a
combination of the joints between the concrete (or concrete like) slabs
and the ridges on the slabs.

Quieter versions of concrete roads were developed, but never used. IIRC
the biggest difference was instead of the ridges, they laid the concrete
smooth and then when almost solid, they cracked the surface with an
impact machine. That created random grooves at all angles, that didn't
cause the tyres to "sing." By then though everyone was moving on to
tarmac, so we get roads that need resurfacing on a regular basis (more
regular than they actually get) and need a lot of maintenance and repair
inbetween.
