How does thermal expansion affect bridges? | Socratic

Jul 16, 2014 · Thermal expansion can affect bridges with either expanding or contracting the bridge (or, by essentially distorting it's shape). If a bridge gets very heated, the road bed will expand. On the other hand, if the bridge is cooled, the road bed will retract. These changes in the bridge may seem initially insignificant, but with constant temperature changes, there will be constant and pervasive ...

Causes of cracking in roads - rhino-uk
