I believe we have relatively narrow markings compared to what I've seen in Germany or Denmark.

How about our "blokmarkering" ?

Yeah, but those are not the regular markings... Only at exits and near intersections.

your and especially the belgian markings are usually also much shorter if i remember correct, giving a different feeling for the road.

Yeah, what's the point of putting those concrete blocks? This exit is specially made for Smart cars?

It's two meters wide. A caravan or camper doesn't fit through it, but many travellers were a little too late to discover that. Someone from the Dutch autosnelwegen reported the "schleuse" was full of mirrors and damaged cars and other auto parts.

Why have they done that?! That seems highly unsafe...

whats the speed limit there? cant be higher than 40 kmph ...

looks like the concrete corridor is an exit and was put there to prevent people from the main highway to change into the exit lane and mix up with traffic entering the highway ... I just dont get whay they put the right concrete barreer ...

They had to build that because of the Fulda bridge. This bridge is no longer stable enough to handle HGVs. If there are too much HGVs on the bridge, the bridge can collapse!
First there were only signs but too much HGV-drivers ignored them, so they must do this to prevent the bridge from collapsing without closing the road.

But as far as I know, the bridge is closed for all traffic in the meantime...

And the limit was 40 kmph.

So here's my next question for everyone who drives. When you see, wider, clearer and brighter markings, does it affect the way you drive? From what I've heard, some people say that clearer markings can decrease driver fatigue by making it easier to see the road. What were your experiences?

I think it's especially an issue of contrast, and driving at night and during rainfall. German pavement is usually grey, and that gives lesser contrast than the intense black asphalt they use in the Netherlands or France.

Do you know the specific types of concrete/asphalt they use in Germany and the Netherlands?

The contrast issue is a big problem for concrete highways in the U.S. We use Portland Cement Concrete and its so bright sometimes that black paints are used along with white paint to mark lanes.

Older Autobahns have concrete slabs, but newer seems to have DAC (Dense Asphalt Concrete). SMA is also used (Stone Matrix/Mastic Asphalt), however, I'm not very well educated on pavements like professionals. However, I do know they very rarely use PAC (Porous Asphalt Concrete), as opposed to the Netherlands and France where the majority of the motorways are PAC.

PAC is 2 - 3 times more expensive than DAC, and there's also double layer PAC, and other silent pavements which are even more expensive. Noise reducing comes at a high price.

So does Dense Asphalt Concrete and Porous Asphalt Concrete have cement mixed with asphalt?

I've heard of names similar to that, but not with the word Concrete in there. The terms I know are Dense-graded Asphalt and Open-graded asphalt (porous).

wow! do you have a photo of that?

and I always thought that this is bright (well, ok, when you're driving there it seems to be brighter than on the photo here):
A3 Frankfurt => Köln, exit 35 Neustadt/Wied

Here's a small one that kind of uses black paint. That's not what I meant though, I'll try to find a better one.
