Alternating frost and thaw: more potholes than in a long time

2024-01-30T16:18:55.432Z

Highlights: Winter has been unusually hard on the roads in the district this year. Potholes turn many routes into real bumpy roads. The B 2 near Germering suffered particularly badly. The damage cannot be repaired quickly, especially on the B2. In winter, potholes are usually only temporarily repaired with so-called cold mix. Laying hot asphalt is only possible to a limited extent in cold temperatures. But according to the building authority, the cold mix can only be used for minor damage. The State Building Authority is currently installing around 36 tons of cold mix per week.

The winter has been unusually hard on the roads in the district this year.

Potholes turn many routes into real bumpy roads.

The B 2 near Germering suffered particularly badly.

Alling/Germering – The speed limit will be 50 there for the next few weeks. But there are also many holes in the streets in inner town.

Drivers should move quickly on federal highways.

As a rule, the speed limit is 100 there. However, on the B 2 eastwards from Germering, you are currently only allowed to drive at a speed of 50 kilometers per hour.

The reason for this is the unusually large number of, and sometimes deep, potholes in the asphalt.

Alternating frost and dew

“In particular, the many freeze-thaw cycles this winter have led to the damage to the roads,” explains Marcus Dörner, spokesman for the State Building Authority in Freising, which is responsible for the federal and state roads in the district.

Water penetrates into smaller cracks and freezes at sub-zero temperatures.

“The explosive force of the ice causes the cracks to enlarge or even lead to breaks in the asphalt and, over time, to potholes,” says Dörner.

Only provisionally

The damage cannot be repaired quickly, especially on the B2.

In winter, potholes are usually only temporarily repaired with so-called cold mix.

Laying hot asphalt is only possible to a limited extent in cold temperatures.

But according to Dörner, the cold mix can only be used for minor damage.

“However, the damage on the B 2 is so extensive that it is assumed that temporary repairs with cold mix cannot create a road that is sufficiently safe for traffic.” The damage could not be permanently repaired with hot asphalt until March at the earliest.

This is how long the speed limit is 50 on the busy route.

Big damages

The building authority also recorded major damage on the state road between Moorenweis and Jesenwang and on the Alling through town – also a state road.

Traffic there is even slowed down to 30 kilometers per hour.

“The frost caused a lot of damage,” reports Alling’s mayor Stefan Joachimsthaler.

This causes discontent in the community.

But there is also damage on local roads.

However, citizens would now have to wait longer for renovation.

The reason is the abolition of the so-called road expansion contribution statute.

The Free Voters in particular campaigned for their abolition at the state level.

There are flat rates from the Free State as compensation.

But they are far too low, says Puchheim's mayor Norbert Seidl.

Therefore, municipalities must prioritize road renovation.

Overall, Puchheim is doing quite well with its streets, according to the town hall boss.

36 tons of cold mix per week

However, on some sections of federal and state highways the situation is completely different.

That's why the State Building Authority is currently installing around 36 tons of cold mix every week.

In addition, the road maintenance departments have optimized their inspection intervals and will check particularly affected routes more often, explains authority spokesman Marcus Dörner.

The public also repeatedly receives information about damage to the roadways.

The building authority is grateful for this.

Dörner stands up for the employees who work in wind and weather to keep the roads in good condition.

“They do their best and do an excellent job.”
