North Rhine-Westphalia: Motorway and road officials: Coating withstands heat

Hamm/Gelsenkirchen (dpa/lnw) - According to experts, the roads in North Rhine-Westphalia can withstand hot days with temperatures of around 40 degrees without major damage. A spokesman for Autobahn GmbH Westfalen said on Tuesday that modern road surfaces can handle a day or two of great heat.

Bumps in the road - the so-called "blow ups" - would therefore only be possible on a concrete roadway - but they only accounted for a small proportion of the motorways. These routes were given more attention on Tuesday.

Long-lasting heat with temperatures of more than 30 degrees usually does not harm the federal and state roads, said a spokeswoman for Straßen.NRW. In the meantime, one comes to temperature ranges in which, in rare cases, deformations of the softened asphalt can occur. But you build according to the current standard. Should roads nevertheless "deform" after long periods of heat, if this is noticed during the route inspection, then it will be renovated.

A spokesman for the Rhineland branch of Autobahn GmbH said that no heat damage had occurred this year.
