Many of the photos used in this Appendix are from the LTPPDistress Identification Manual.1 Asphalt Pavement Distresses Fatigue (Alligator) Cracking Fatigue (also called alligator) cracking, which is caused by fatigue damage, is the principal structural distress which occurs in asphalt pavements with granular and weakly

Before the appropriate repair strategy can be applied to a distressed asphalt pavement, the type and extent of the deterioration must be understood, and the cause of the distress must be identified. The common types of pavement distresses include: cracking; distortion; disintegration; skidding hazards; and surface treatment distresses.

Pavement Surface Condition Field Rating Manual for Asphalt Pavements Northwest PavemenNorthwest Pavementt Management AssociatioManagement Associationn
These inspection procedures offer a method of determining pavement condition through observing and recording the presence of specific types and severities of defects or distresses in the pavement surface. The elements of pavement condition rating are as follows: 1. The type of defect. 2. The severity of the defect. 3.
is tasked with executing a pavement condition assessment on about 5,400 miles of National Park Service roads and parkways. Foremost in setting up the basis of pavement distress identification is employing the distress identification protocols used by FHWA. There is no single distress
Two forms of pavement distress were noted on recent asphalt concrete overlay projects. A general loss of wearing surface under traffic action, termed surface ravelling, was
Asphalt begins to degrade beginning the day it is laid down. If not properly maintained, your asphalt will likely degrade to the point where your pavement will need

Theer is many differents forms of Distortions in an asphalt pavement are caused by instability of an asphalt mix or weakness of the base or subgrade layers. These distresses may include rutting, shoving, depressions, swelling and patch failures.Rutting. Rutting is a linear, surface depression in the wheelpath.
Evaluation of Rutting Distress for Asphalt Concrete Mixture Using Abaqus associated with asphalt pavement hardening” form for pavement rutting
Asphalt rutting remains one of the leading forms of flexible pavement distress and is classified as a longitudinal surface depression located along the wheelpath. There is no exact severity levels defined for this type of distress, instead measurements of surface depressions are used for analysis.
the distress are present in the form of surface cracking . For this investigation, we focus on asphalt pavement. Since pavement forms a large part of our transportation infrastructure, a number of distresses have been identified and their characteristics cataloged . Four common pavement crack types are illustrated in Figure 1.1, and
