The underlying cause of 'D-cracking' in concrete pavements is the freeze-thaw deterioration of coarse aggregate particles near joints and cracks. D-cracking is a distress mechanism specific to concrete pavements, characterized by a series of closely spaced, crescent-shaped cracks that typically develop parallel to joints, cracks, and free edges of the pavement. The primary culprit is coarse aggregate that is susceptible to freeze-thaw damage. These aggregate....
