Asphalt Pavement Transverse Cracking

Transverse/Thermal Cracking in Asphalt Pavement: …

Cool temperatures cause the thermal cracking in asphalt pavement and the constant weight and pressure from overuse and moving vehicles worsens it. Transverse asphalt cracking starts on the surface of the pavement and then gradually sinks deeper and deeper below the surface if the transverse cracks are not immediately repaired. The damage will ...

Transverse Cracking of Asphalt Pavements - Iowa

2015-6-19 · Transverse cracking of asphalt pavements has been a problem since asphalt was first used as a pavement material. The sug­ gested causes for this phenomenon consist of, but are not limited to, ambient temperature changes, base or subbase, temperature susceptibility of the asphalt, grade of asphalt, mix stiffness,

Transverse (Thermal) Cracking | Washington Asphalt ...

Cracks perpendicular to the pavement's centerline or laydown direction. Usually a type of thermal cracking. A large transverse crack caused by the pavement's contraction in cold weather. The crack has subsequently been patched as a temporary fix. Another transverse crack caused by thermal contraction during cold weather.
