Behaviour of bituminous mixture under creep static and cyclic compressive loading

1 Behaviour of bituminous mixture under creep (static) and cyclic compressive loading 

In a repetitive loading (cycle loading), the sum of the infinitesimal unrecoverable deformations is the cause of pavement deformation, which appears in the form of rutting. 

If the stiffness modulus is to be determined, the applied stress and the total per- 

The assessment of the asphalt performance in resistance to permanent deformation is determined with reference to either creep rate and creep modulus or creep rate and cumulative strain after n load applications, or permanent shear strain, depending on the test employed.
