Structural distress refers to pavement damage that indicates a weakness or failure in the pavement's load-bearing capacity. This means the pavement layers are no longer able to adequately distribute traffic loads, leading to potential failure of the pavement structure. Examples of structural distress include fatigue cracking (also known as alligator cracking), rutting (permanent deformation in the wheel path), and faulting (vertical displacement between adjacent pavement slabs). These distresses are....
