Asphalt can develop a number of problems that require repairs over time. One of the most common types of problems or damages that occurs on asphalt are cracks. There are many different types of cracks that develop on asphalt, and each require the proper repairs. Andersen Asphalt & Striping would like to define all the different types of asphalt cracks and who to call when cracks need to be repaired. There are many different types of cracks that can develop on asphalt pavement. The types of repairs needed will be determined by the type of crack and its location. The different types of cracks develop depending on the surrounding environment and temperature. Following are some of the common types of cracks that develop on asphalt pavement.
Fatigue of Alligator Cracking in Asphalt
Fatigue cracking is also sometimes called alligator cracking. The nickname alligator crack was given due to its alligator skin like appearance. Fatigue cracking is caused by load or weight related deterioration. As a result, the base course or subgrade becomes weakened which will cause alligator skin like cracks. Fatigue cracking can also be due to the pavement’s thickness and or overloading.
Asphalt Block Cracking
Block cracking is a very serious problem to occur. Block cracking is when there are large pieces of cracked asphalt that are bigger than a square foot and are usually a rectangular shape. Block cracks usually cover a large area on the surface of the asphalt and can occur in areas with no traffic. Block cracking is usually caused by shrinking of the asphalt due to temperature cycles.
Edge Cracking in Asphalt
Edge cracking is when longitudinal cracks occur within one to two feet of the asphalt pavement’s edge. Edge cracking occurs when there is no support at the edge of the pavement. Often the asphalt will need to be redone with proper support.
Asphalt Longitudinal Cracking
Longitudinal cracking develops parallel to the center-line of the asphalt pavement. There be a few different causes of longitudinal cracks. One can be due to poorly constructed joints, shrinking of the upper asphalt layer, and cracks reflecting up from the underlying layer of the asphalt. Longitudinal segregation is caused by improper paver operations or processes. These types of cracks are not due to load related problems.
Transverse Cracking in Asphalt
Transverse cracking develops roughly perpendicular to the center-line of the asphalt pavement. Transverse cracking is the result of asphalt shrinking of the upper asphalt layer. Transverse cracking can also occur when other cracks are present on the asphalt pavement.
Reflection Cracking in Pavement
Reflection cracking is when a crack forms over the joints and/or space of concrete pavement and the overlay of asphalt pavement. Reflection cracks are the result of old asphalt and is a sign that the asphalt needs to be replaced.
Slippage Cracking in Asphalt
Slippage cracking is when a crescent-shaped crack forms on the surface of the asphalt. Slippage cracks occur when low-strength asphalt is mixed with a low quality bonding agent that is used in between the pavement layers. These cracks can form when vehicles brake frequently on the pavement surface.
