Early Cracking of Concrete Pavement - causes and repairs

Sep 12, 2009 · Unexpected changes in the weather during and after construction can induce uncontrolled cracking despite the adoption of proper jointing system. Because of the complexity of interrelated factors, uncontrolled cracks will occur in some pavements. Theses cracks generally develop within the first thirty to forty five days.

Pavement Crack Sealing | CRAFCO

Sealing cracks quickly after they develop reduces the damage to the pavement. The longer the cracks remains sealed, the longer the pavement will perform. Visually inspect pavements every year to identify and seal new cracks. Cracks greater than 1/8” (3 mm) must be sealed to achieve the best protection of the pavement.

13 Pavement Defects and Failures You Should Know ...

More severe cracks should be fixed by removing the cracked pavement layer and replacing it with an overlay. Longitudinal (Linear) Cracking. Longitudinal cracking are cracks that are parallel to the pavements centerline or laydown direction. These can be a result of both pavement fatigue, reflective cracking, and/or poor joint construction.
