Heat wave stops road construction in Görlitz - completion is delayed!

The road construction work on Promenadenstraße in Görlitz is in full swing, but the heat thwarts the craftsmen. Due to the high temperatures, there are delays in asphalt construction between the Kastanienallee and Friedersdorfer Straße. These temperatures not only slow down the asphalt, but also affect its compression and thus the entire strength of the covering. Originally, the first construction phase should be completed by next Monday. Due to the adverse weather conditions, this appointment has now shifted to July 11th, such as Sächsische.de reports.

It becomes particularly delicate in the first section, which is built between chestnut avenue and elderberry path under full closure. Road users have to prepare for limited passage by July 11th. In the second construction phase, the degree of which is planned for July 25, the diversion is regulated by a light signal system. Here, a roadside side is set up for traffic to drive vehicles safely through the construction site.

sunny danger: heat damage in the asphalt

High temperatures in summer are not only exhausting, but also a major challenge for the street infrastructure. The asphalt, a mixture of gravel stones and bitumen, becomes soft and deformable at extreme temperatures from 60 ° to 70 ° C. According to car driver side.eu, damage such as cracks, holes and dangerous "blow-ups" can occur. These sudden damage is not only a danger to the street itself, but also for drivers who could drive over it.

Many roads are particularly affected in East Germany, since unsuitable building materials are often used there. Even if the materials are generally suitable for high temperatures, extreme heat periods can significantly impair their strength. This can be seen, among other things, by the formation of gear grooves, which not only reduce driving comfort, but also increase the risk of aquaplaning.

innovative solutions against the heat

In order to counter the challenges of heat, work is already being done on innovative road surfaces in Hesse. An example of this is the special asphalt "climate adhesion", which is known for its bright surface and reflects the sun's rays better. This road surface can absorb and store up to 125 liters of rainwater per square meter, which contributes to the evaporation cold and at the same time relieves the sewage system, such as the wetter.com reported.

In addition, a geothermal solution is being worked on, in which cold water circulates through pipes in the asphalt layer. This should not only cool down in summer, but also prevent smoothing in winter. So far, the previous tests in Hesse show that the asphalt mixtures used are robust compared to high temperatures and that significant damage is largely absent.

For all road users, it is important to be particularly attentive at high temperatures and, if necessary, to adapt to speed restrictions and diversions. Motorcyclists in particular should avoid endangered routes or find out well to get to the goal.
