of the rutting in the asphalt-bound layers occurs in the top 7 to 10 cm of the pavement (2-7) The rate and magnitude of rutting depend on external and internal factors External fac tors include load and volume of truck traffic, tire pressure, temperature, and construction practic Internal factors include.

Pavement rutting is defined as surface depression in the wheelpath Pavement uplift (shearing) may occur along the sides of the rut Ruts are particularly evident after a rain when they are filled with water There are two basic types of rutting: mix rutting and subgrade rutting.

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.

A rut is a depression or groove worn into a road or path by the travel of wheels or skis Ruts can be formed by wear, as from studded snow tires common in cold climate areas, or they can form through the deformation of the asphalt concrete pavement or subbase material The main reason is heavy loaded truck acts more pressure than assumed during the construction of roads.
