Permanent deformation in any of a pavement’s layers or subgrade usually caused by consolidationor lateral movement of the materials due to traffic loading. Specific causes of rutting can be: 1. Mix rutting. Improper mix design or manufacture (e.g., excessively high asphalt content, excessive mineral filler, … See more Surface depression in the wheelpath. Pavement uplift (shearing) may occur along the sides of the rut. Ruts are particularly evident … See more Ruts filled with water can cause vehicle hydroplaning, can be hazardous because ruts tend to pull a vehicle towards the rut path as it is steered across the rut. See more A heavily rutted pavement should be investigated to determine the root cause of failure (e.g. insufficient compaction, subgrade rutting, poor mix design or studded tire wear). Slight ruts (< 1/3 inch deep) can generally … See more WebJun 10, 2024 · Rutting in asphalt mixes is a common type of distress in pavements with thick asphalt layers. It is more severe for pavements subjected to high pavement temperatures, slow moving, uphill in ...
