Stress path investigation of fatigue characteristics of cement stabilized macadam

Fatigue strength is the core of pavement structure design. For semi-rigid base asphalt pavement, the anti-fatigue design of cement stabilized macadam is the key to the entire pavement design process. However, the structural layer of cement stabilized macadam is in a complex stress path, and the traditional S-N fatigue equation is various in different stress paths. Single S-N fatigue equation cannot truly reflect the actual pavement’s stress path...
