Abstract: Temperature change of the semi-rigid base course is one of the reasons of appearance of the reflective crack. The stress intensity factor of the semi-rigid asphalt pavement is calculated with finite element method. Sensibility analysis is made on the parameters (modulus, thermal expansion coefficient, thickness) affecting the magnitude of the stress intensity factor. Finally, a conclusion that the graded gravel can reduce the reflective cracking, is drawn.

Key words: reflective crack, semi-rigid pavement, gravel interlayer, stress intensity factor
