I recently had our flats' car park resurfaced on behalf of the residents.
The marks shown in the picture were left on the finished surface. We thought it was dirt, which would wash off in the first heavy rain, but that had no effect.
One of our residents even went out with a scrubbing brush and some dilute detergent, but the marks seem to be permanent.
From here, they look like run-off marks from the roller. In essence, dirty water has been used to wet the drums on the roller and this has transferred to the mac surface. Unless it's summat especially nasty, they should weather out in a week or two.

Ok thanks. I've got the guy coming round this afternoon to look at three depressions that I've complained about, so I wanted to raise this as well if it should be a cause for concern.
As I said, it won't scrub off with a scrubbing brush, so I was concerned that this macadam itself ("30mm thick wearing course-AC dense surf") was tainted and the marks were there for good.
from the pictures the marking kinda shows a poor rolling pattern, or even repeated movements of a whacker plate. if it's not dirty water, look close up and check that the surface binder hasn't been scratched off exposing the (limestone?) aggregate. either way, in most cases it is purely aesthetic and will weather in as Tony says in time - as it will all look dull & grey.
i used to love using tarmac, but got fed up with getting my asphalt

The guy didn't turn up - he was supposed to be coming late afternoon, after finishing on site elsewhere.
At his request, I had drawn a chalk outline of the dips that needed filling - after spending quite a long time filling them with a hose. One of them is up to 25mm deep, and covers an area of about 3m * 2m.
I'm disappointed really, as I was pleased that the lowest of the three quotes came from the biggest firm.
Still, they're not getting their £3,500 until it's sorted. My real concern though is that as this isn't an area in which I have any expertise, I will never be really confident that it is sorted.
Hmmmm well that speaks volumes for the guys attitude doesn't it??
6m2 low by as much as 25mm? That's inexcusable! There is no way to repair that without it sticking out like a sore thumb - it will always be a patch on your new area.
Still, at least you haven't paid them yet.
