27/02/2019  Reflection cracking happens because of asphalt pavement overlays that have been placed over a pavement structure that has been cracked or jointed. There is then shifting or movement of the old pavement. These cracks or joints can reflect from that pavement to the surface. Crack sealant can sometimes fix low severity cracks. Pavement that is cracked

Reducing the Problem of Transverse Cracking

Through a 1979 pavement management study, the Iowa DOT became a participant in a five state Federal Highway Administration (FHWA) study of "Transverse Cracking of Asphalt Pavements".

Common distresses in asphalt pavements ...

Thermal cracking occurs in the form of transverse cracking, which is defined as cracks that are predominantly perpendicular to the pavement centerline. These cracks occur at regular intervals. Thermal cracks can be caused by the fracture of asphalt mix due to a severe drop in temperature or by thermal fatigue caused by repeated low- and high-temperature cycles. The

Field and laboratory testing indicated that severities of transverse cracking were influenced by high variations in asphalt layer moduli, pavement thicknesses and low cracking resistance of both pavements, in addition to extreme low temperature events and temperature differentials.

Best practices for crack treatments in asphalt pavements

Treating cracks in asphalt pavements is a major part of every maintenance engineer’s work. The objective of any crack treatment is to minimize the intrusion of water into underlying layers of the pavement structure. Such water infiltrates the base layers of the pavement and may lead to pavement structural failures. Crack treatments fall into two broad categories – crack sealing
