  • Transverse/Thermal Cracking in Asphalt

    Transverse cracking is most noticeable on concrete pavement that gets a high level of daily traffic. Cool temperatures cause the thermal cracking in asphalt pavement and the constant weight and pressure from overuse and moving vehicles worsens it.

  • 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.

    Thermal cracking of petroleum is also often discussed in chemistry classes while introducing students to basic chemical concepts which come up in the refinery industry. The term thermal cracking is also used in reference to

  • Investigation of Low Temperature Thermal

    Thermal cracking is primarily a result of the low temperature environment. After the thermal crack develops, water can enter the crack and cause ravelling of the joint and/or loss of base support. This significantly decreases the rideability of the pavement. In some parts of Colorado, thermal cracking is the primary distress.
