What is a bridge substructure?
The foundational or floating structure supporting the road surface portion of a bridge.
Why do the road on the bridge freeze quicker?
There are three main reasons why bridges freeze before roads. The first is that a bridge is exposed from below and above, unlike a roadway. Roads don't freeze over as quickly because they can take advantage of insulation and warmth from the soil below. Bridges, on the other hand, are beset with cold temperatures from all sides, which can cause them to ice over quickly. Bridges also freeze rapidly because many of them are located over cold spots, like frozen rivers or deep ravines. The third reason that bridges freeze before roads is their construction. The materials used in the core of a bridge are excellent heat conductors. As a result, they draw heat out from the inside of the bridge, transferring it to the surface where it is quickly lost when ambient temperatures are very cold. Bridges often quickly reach the general air temperature, so when the thermometer reads 32 degrees Fahrenheit (0 degrees Celsius), the bridge will freeze .

Explain how a cold winter can damage road surfaces?
During winter, water can seep into cracks in the road surface, freeze, and expand, causing the cracks to widen. This repeated freeze-thaw cycle weakens the road surface, leading to potholes and cracks. Additionally, the use of road salt and de-icing chemicals can further deteriorate the road surface by increasing corrosion and erosion.
What causes the road surface to crack during winter?
The main cause of road surface cracking during winter is the freeze-thaw cycle. When water seeps into the cracks in the road, it freezes and expands, causing the pavement to crack. As this cycle repeats, the cracks widen and can lead to potholes forming in the road surface. Additionally, the use of de-icing salts can also contribute to the deterioration of the road surface.
