Transverse/Thermal Cracking in Asphalt

In most major cities, transverse or thermal cracking in asphalt is a very common problem and a safety hazard because the roads are constantly in use; this is why it is important to hire companies that specialize in transverse crack repair in Toronto.

Low Temperature Cracking in Asphalt Pavements

Thermal cracks can be initiated by a single low temperature event or by multiple warming and cooling cycles and then propagated by further low temperatures or traffic loadings. The current Superpave specification attempts to address this issue by specifying a limiting low temperature for asphalt binders.

What is Thermal Cracking? (with pictures) - wiseGEEK

The term thermal cracking is also used in reference to concrete, asphalt, and similar materials. In this case, low temperatures make the material prone to cracking. Things like asphalt are elastic at temperate and high temperatures, deforming as they are stressed, but when it is cold, the material may crack or fracture.
