PIC PIC Pavement Distress & Failure Analysis

Question 1

Which type of pavement distress is characterized by an interconnected series of cracks forming a pattern resembling an alligator's skin?

Accepted Answer

Alligator (fatigue) cracking

Answer

Alligator or fatigue cracking forms an interconnected crack pattern resembling an alligator hide and indicates structural failure from repeated traffic loading.

Question 2

Rutting in an asphalt pavement is best described as:

Accepted Answer

Permanent surface deformation in the wheel paths

Answer

Rutting is permanent deformation appearing as longitudinal depressions in the wheel paths caused by consolidation or lateral movement under traffic loads.

Question 3

Bleeding (or flushing) on an asphalt surface is caused by:

Accepted Answer

Excess asphalt binder migrating to the surface

Answer

Bleeding occurs when excess asphalt binder migrates to the pavement surface, creating a shiny, sticky film that reduces skid resistance.

Question 4

Raveling in asphalt pavement refers to:

Accepted Answer

Progressive loss of aggregate particles from the pavement surface

Answer

Raveling is the progressive disintegration of an asphalt surface through the loss of aggregate particles, often caused by inadequate compaction or aged binder.

Question 5

A paving inspector notices transverse cracks spaced evenly across a pavement. This pattern is most commonly associated with:

Accepted Answer

Thermal contraction of the asphalt layer

Answer

Transverse cracks spaced at regular intervals are typically caused by thermal contraction of the asphalt binder during temperature drops.
