A comprehensive overview on main distress mechanisms in composite pavements

Fatigue cracking of cement-treated bases, instability rutting, top-down cracking, shrinkage cracking, reflective cracking and thermal fatigue cracking have been identified as the most common distresses affecting the service life of composite pavements, which consist of an asphalt course on top of a cement-treated base. These distresses prevent composite pavements from being considered long-life pavements, which are defined as pavements in which the structural elements may last indefinitely. This paper analyzes different factors leading to the initiation and propagation of the distress mechanisms, as well as the material properties required to improve the long-term performance of composite pavements.
