WebRutting refers to permanent deformation of the asphalt surface that accumulates in the wheelpaths. It is primarily the result of repeated traffic loading cycles. Rutting may be accompanied by fatigue cracking and other distresses, making it a serious concern and potential indicator of pavement failure. 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 after rain when they are filled with water. There are three basic types of rutting: mix … 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). … See more

Rutting in a Pavement Structure - Global Road Technology - GRT
WebThe stresses in the pavement structure caused by the moving wheel load, 2. The time dependent response of the road materials and 3. The stresses induced by impact loads. ... The stresses and strains in this position are the most critical for the development of Mode 1 rutting. C. The vertical compressive stress and strain on the top of the subgrade WebRoughness is an important pavement characteristic because it affects not only ride quality but also vehicle delay costs, fuel consumption and maintenance costs. The World Bank found road roughness to be a primary factor in the analyses and trade-offs involving road quality vs. user cost (UMTRI, 1998 [1] ).
