| Abstract: | Drying principle and temperature shrinkage principle of semi-rigid material as well as cracking and fatigue failure of semi-rigid material are analyzed.Through calculation of fatigue life of different strong semi-rigid pavements,it is indicated that improving foundation bearing capacity can significantly increase the life and durability of semi-rigid pavement.On the basis of analysis,this paper also introduces the prevention and treatment of semi-rigid pavement diseases. |
