**8. Conclusion**

The results of this study allow drawing the following conclusions for the fatigue failure of the asphalt concrete pavement of a highway:

**1.** In Kazakhstan, the cracks of various types on the asphalt concrete pavements (fatigue, thermal, reflected and sagging) are not identified separately. The staged character of the fatigue failure was not considered. Maximum allowable characteristics, including the fatigue ones, were not determined as well. In the USA, the fatigue cracks are identified separately from other types of cracks, three levels for their development have been determined, but the relation is not considered between these levels.
