Performance Tests for Rutting – Pavement Interactive

For asphalt pavements, rutting is one of the most serious forms of pavement distress, and severe rutting is a significant cause of pavement failure. To prevent rutting, the pavement structure needs to provide sufficient support for the roadway surface, while the design and construction of the asphalt mix must create a pavement that can resist ...

Nov 12, 2008  Rutting is a surface depression within the wheel path. Rutting results from a permanent deformation in any of the pavement layers or subgrades, usually caused by consolidation or lateral movement of the materials due to traffic loads. When the upper pavement layers are severely rutted, the pavement along the edges of the rutted area may be raised.
