there's nothing wrong with concrete German autobahns, you just need to maintain them well, otherwise this kind of things happen:

A18, Poland. Concrete road which hasn't been well-maintained for about 70 years.

It is completely new to me that asphalted roads stay dry in the rain. I wonder why so much effort is spend on cross slope.

Anyway, the biggest advantage of asphalt is its flexibility. The economical superiority of concrete pavement stretches as far as large-scale pavement. That's why mainly carriageways of motorways and airport runways are constructed this way. For narrower roads this advantage shrinks to zero and below.
The biggest advantage of concrete pavements is the far better visibility in the dark.

I prefer concrete. Much better visibility in the dark.

Ugly and noisy, what is being worsened by this semi-tunnel effect. I causes more reflections of the noise.

I despise concrete roads. They make me have to wear sunglasses even when there's no sun.

Well, after 71 years of utilization it is still in use(till 2009), with numorous trucks driving on it, so it is no way to maintain it anyhow for such a long period of time.

Yes, it will be reconstructed in the coming decade, so it's the best to leave it like this. Furthermore, when you drive from NL to southern Poland, the A18 is the shortest route, but when the A4 is finished, it is only 20 km longer, so it is better to use the A4 then. (sorry for going off-topic..)

Don't worry. It is quieter there than you think. The porous masonry absorbs most of the noise.

There is the asphalt that temperature does not rise.
There is color asphalt.
There is asphalt absorbing water.

The grip powers of the tire are different.(An accident rate)

btw: when I was in Poland, I saw that most new highways are concrete, while the new expressways where surfaced with asphalt. Am I right?

No, 60 km further, A11 in Germany.

And this is not so simple with A/S roads surface in Poland. A4 and A18 are exceptions. Other roads (A2, A4) are asphalted.

No, the S6 is all-asphalt

The only half concrete - half asphalt road in Poland is A18 secion border Trzbiel exit(10 km). Westbound lane is concrete, eastbound - asphalt

mixed, baby



A3, Köln, Germany

as a color, I like it when the road is so red-brownish. Unfortunately, the few sections I know with that color, are mostly old and in bad condition.
