Germany's Autobahn: World's Smoothest Highway
The Autobahn in Germany is known for being one of the smoothest highways in the world.
It's so well-built that driving on it feels like gliding on glass.
The road is very thick and strong, which helps it last a long time without needing many repairs.
Germany has been working on making their roads better for over a century.
Other countries like Japan, Switzerland, Austria, the UAE, and Singapore also have very smooth roads, but the Autobahn is still considered the best.
India is trying to build better roads too, but they have some challenges like too many overloaded trucks and not enough maintenance.
Germany's Autobahn is renowned for its smoothness and durability, with a pavement thickness of 60 to 90 centimetres.
The Autobahn's construction involves a multilayered process with precise measurements and laser-guided levelling for a near-perfect surface.
The road's top surface is replaced every 7 to 12 years, ensuring it retains its smooth finish and can last 30 to 40 years.
Germany's focus on road quality dates back to the 1920s, with major modernisation in the 1960s and continuous upgrades since then.
India is building expressways at a rapid pace, but challenges like overloaded trucks and insufficient maintenance prevent them from achieving the same level of smoothness as the Autobahn.
