    Winter service in the midst of summer

    Road salt and NaCl against pavement damage

    To prevent serious damage to the road surface due to the extreme temperatures, the timber yards and communal service staff situated around the area of the Rhine and Gelderland in the Netherlands, have recently sent out their vehicles for winter service. The dispersal of road salt and natrium chloride shall prevent possible damage to the road surface and therefore swathe the dampness caused by the sun´s heat.

    Usually the tarmac does not melt among temperatures between 320 and 350 degrees Fahrenheit but old pavements may start to getting soft by temperatures between 104 and 140 degrees Fahrenheit.

    Also there is a high thread of so called "blow ups". Concrete slabs start to expand in the heat. When the slabs collide, massive compressional stress may cause currogations in the road surface, causing momentous road accidents.
