Fatigue Cracking | Pavement Interactive

Series of interconnected cracks caused by fatigue failure of the HMA surface (or stabilized base) under repeated traffic loading. In thin pavements, cracking initiates at the bottom of the HMA layer where the tensile stress is the highest then propagates to the surface as one or more longitudinal cracks.

Crocodile cracking - Wikipedia

Fatigue cracking is an asphalt pavement distress most often instigated by failure of the surface due to traffic loading. However, fatigue cracking can be greatly influenced by environmental and other effects while traffic loading remains the direct cause.

Causes·

Fatigue Cracking Pavement: Who, What, When,

Fatigue Cracking of Pavement - UK Essays

Introduction to fatigue cracking of pavement. Fatigue or alligator cracking is the most common type of pavement distress, it is infact the major one. This is the type of distress in which series of interconnected cracks appears due to the fatigue failure of the HMA surface when the pavement experience repeated traffic loading.

Understanding asphalt pavement distresses – five

Pavement distresses and associated treatments are covered in more detail in the Asphalt Institute�s manuals, MS-4, The Asphalt Handbook, and MS-16, Asphalt in Pavement Preservation and Maintenance. #1 Cracking Several different types of cracks can develop in asphalt pavements. The repair depends on the type of crack.

Appendix A Pavement Distress Types and

Block cracking is the cracking of an asphalt pavement into rectangular pieces ranging from about 1 ft to 10 ft on a side. Block cracking occurs over large paved areas such as parking lots, as well as roadways, primarily in areas not subjected to traffic loads, but sometimes also in loaded areas.

Pavement Solutions for Cracks and Joints (Less than

Pavement Cracks and Joints. Pavement cracks and joints are not the same. Cracks are caused by deterioration of the pavement. Obviously, pavement is best when it is first constructed. As sunlight oxidizes the pavement and seasonal temperature changes expand and contract the pavement, cracks form.

CRCPavement.org – Cracking

Reinforcement serves to keep cracks closed as keeping the cracks tight is essential in maintaining load transfer through aggregate interlock. This, in turn, reduces pavement flexural stresses due to traffic loading. Tight cracks are also beneficial to avoid water infiltration and intrusion of incompressibles through the cracks.

Longitudinal / Transverse Cracking (8) Description. Longitudinal cracks are parallel to the pavement’s center line or laydown direction. They may be caused by (1) a poorly constructed paving lane joint, (2) shrinkage of the AC surface due to low temperatures or hardening of the asphalt, or (3) a reflective crack caused by cracks beneath the

Low Temperature Cracking in Asphalt Pavements

Low temperature cracking is the most prevalent distress found in asphalt pavements built in cold weather climates. As the temperature drops the restrained pavement tries to shrink. The tensile stresses build up to a critical point at which a crack is formed. Thermal cracks can be initiated by a
