Heat Danger: Why High Temperatures Are Dangerous for Roads and Highways

Extreme heat is posing a significant threat to Bavaria's road infrastructure, leading to dangerous "blow-ups" where concrete slabs buckle and lift. The Autobahn GmbH is currently undertaking repairs on the A93 highway in the Oberpfalz region due to such heat-induced damage. Specifically, the section of the A93 between Weiden-Süd and Luhe Wildenau, heading towards Regensburg, has experienced buckling concrete slabs. As a result, the left lane remains closed and is expected to reopen by next week at the earliest. The damaged slabs will need to be replaced to ensure safety. The Autobahn GmbH is urging drivers to exercise caution and remain vigilant. Any observed road damage should be immediately reported to the police. Adhering to posted speed limits is also crucial, as excessive speed can exacerbate the dangers posed by these road defects. These "blow-ups" are particularly prevalent on older concrete road sections that have endured significant stress and undergone multiple repairs. The likelihood of such damage increases substantially when outside temperatures reach approximately 30 degrees Celsius (86 degrees Fahrenheit). The State Building Authority of Würzburg has also reported similar heat-related asphalt damage in the Würzburg district, where the top layer of the road surface is peeling off in spots.
