Traffic-associated fatigue damage is one of the major distresses in which flexible pavements fail. This type of distress is the result of many thousands—or even millions of wheel loads passing over a pavement. The TRB National Cooperative Highway Research Program's pre-publication draft of NCHRP Research Report 982: Relationships Between the Fatigue...
