How thick is the asphalt on the Autobahn?

Current as well as all planned projects for “Autobahnen” (Switzerland’s express highway or motorways system) will also be largely concrete.

How far does the Autobahn stretch?

8,073 miles
Today’s German autobahn system stretches 12,993 km (8,073 miles, 2016 data) across most parts of Germany. Plans to increase the number and length of autobahns and other highways often meet with citizen opposition on ecological grounds.

Why are there speed limits on the Autobahn?

Congestion building up on a Urban Autobahn (Stadtautobahn). Due to almost constant heavy traffic sections like this often have speed limits, sometimes as slow as 80 km/h. To help maintain safe grades, the Autobahn system is well-endowed with tunnels and bridges.

How is the maintenance of the Autobahn done?

Crews inspect every square meter of the system periodically using vehicles with high-tech road scanning equipment. If a fissure or other defect is found, the entire road section is replaced. Barriers, signs, and other features are also well maintained. Generally the mainline Autobahn routes avoid the metropolitan cores.

What is the thickness of an asphalt runway?

#11051151. The thickness is hardly surprising. Even german Autobahn-motorways are already 2-3 feet thick of asphalt, with crushed stone beyond it. Most of the older ones were built out of thick concrete so that one Herr Hitler’s tanks could use them to move around the country.
