There are some sections of Autobahn built with concrete slabs and they are terrible, even if it were for the noise alone [1]. But they are also problematic when it gets hot -- warped slabs and slabs being lifted into the air by pressure (since the slabs expand) happen regularly. And they are also problematic when it's wet. In other words, they're always problematic.
Concrete Autobahn is mostly replaced with proper asphalt Autobahn when a section is renewed.
[1] Since it's Autobahn many people don't drive a cosy 140 km/h (85 mph) but rather 160-250 km/h (100-160 mph) [and when the road is free 300 km/h, 190 mph, are observed regularly] so I assume the noise is worse on the Autobahn than on concrete highway.
