Cracks & Fissures It is important to repair cracks in pavement to minimize water penetration which softens the ground and will freeze and thaw, causing more cracking or become potholes. There are two main types of cracking that occur in asphalt.
Alligator cracking, longitudinal cracking and transverse cracking are common asphalt cracks that require unique repair methods. Kleenco Construction specializes in these types of repairs and will ensure that your asphalt is safe for years to come.
Block cracking is a series of large (typically one foot or more), rectangular cracks on an asphalt pavementï¿½s surface. This type of cracking typically covers large areas and may occur in areas where there is no traffic.

Shrinkage or block cracks are interconnected cracks that form groups of large blocks with cracks that usually intersect each other at right angles. The asphalt mix losing its flexibility due to age and oxidation normally causes this type of cracking.
Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, as well as the core of …
Alligator cracking in asphalt is a common sign of major damage on driveways, roadways, and parking lots. When this type of damaged has occurred, asphalt crack repair is needed to restore the asphalt surface to its proper form. Alligator Cracking/Fatigue Cracking in Pavement

Sealing and Filling Cracks in Asphalt Pavements FHWA Contact: Monte , 202-493-3144 Background Sealing and filling asphalt concrete pavement cracks is a common road maintenance activity. Specialized materials are placed into or above cracks to prevent the intrusion of water and incompressible material
This type of cracking usually starts from a singular crack and over time with no crackfill, allows water penetration into subbase. This softens the subbase and cause the asphalt to flex more than design, which creates more cracks adjoining the original.
Asphalt shingle cracks due to thermal splitting & defective product: this document tells readers how to identify & explain asphalt shingle cracking or thermal splitting, what causes shingle cracks or splits, and how to distinguish this product failure (which may be entitled to a warranty or class action claim) from other roofing product failures or defects.
Types of Asphalt Cracks and Repair Methods Both shrinkage cracks and stress cracks require slightly different repair methods for maximum effectiveness. Shrinkage cracks are the most common and are caused by asphalt drying out due to oxidation.
Crocodile cracking, also called alligator cracking and perhaps misleadingly fatigue cracking, is a common type of distress in asphalt pavement. The following is more closely related to fatigue cracking which is characterized by interconnecting or interlaced cracking in the asphalt …

The most common type of flexible pavement surfacing in the U.S. is hot mix asphalt (HMA). Hot mix asphalt is known by many different names such as hot mix, asphalt concrete (AC or ACP), asphalt, blacktop or bitumen.
Alligator cracking, also known as pavement fatigue or crocodile cracking, is a common issue for commercial asphalt because it is directly linked to load-related distress. Commercial parking lots, roadways and other surfaces get a lot of traffic, hence why it's common to see these types of cracks.
The two types of asphalt are very similar, but they do have a slight difference. The 41A is also known as the driveway mix, as it is commonly used for driveways. The 41A has a mixture of rock and sand that is very fine in diameter with an oil content up to a 6.0%.
Alligator cracks – The most common types of asphalt cracks, these resemble alligator skin and will spread far and wide across your pavement. They're usually caused by weak areas on the surface or in the base layer of the asphalt.
