Which type of cracking is characterized by cracks that are parallel to the pavement centerline?

Longitudinal cracking is specifically characterized by cracks that run parallel to the centerline of the pavement. This type of cracking often occurs due to a variety of factors, including temperature changes, heavy traffic loads, or inadequate pavement design. It may indicate underlying issues such as poor construction methods or material changes, which can lead to further deterioration if not addressed.

In contrast, block cracking involves a series of interconnected cracks that create rectangular patterns, and alligator cracking features small, interconnected cracks that resemble the scales of an alligator. Transverse cracking occurs perpendicular to the pavement centerline and typically indicates thermal expansion or contraction issues. Understanding these distinctions is essential for effective pavement management and maintenance practices in civil engineering.
