Winter, the coldest of all seasons, is a beautiful time of year – a winter wonderland of snow and ice. But when everything melts, the frost and moisture damage to city streets is not very pretty. Asphalt pavements have a tendency to expand and contract with extreme weather. And so does the ground underneath. In extremely cold weather, when water gets into the ground beneath the pavement, it can freeze into ice which, in turn, will lift the road’s surface. When this happens, we begin to see potholes, pavement cracks and sewer manholes sinking below street level.
Although some of this asphalt erosion does, in fact, settle down after the thaw, most of it causes moderate-to-severe road damage. And this means costly repairs. The cost to repair damaged manholes and potholes can be quite steep. Municipalities bear the financial burden of road maintenance and repair, while the city dwellers must suffer the cost of damage to their cars (from street cracks and potholes) and the inconvenience of traffic congestion and delays (from road construction). Suddenly, the beauty of winter has turned into a beast… of road erosion and damage.
