Summary:
This paper presents the results of a study directed toward the solution of the reflection cracking problem in overlaid
cracked pavements.  Stresses in the overlay pavement near the existing crack are estimated using a recently developed
finite element program for the pavement system idealization.  Crack tip stresses for both traffic leading and temperature
changes are calculated; the influence of a stress absorbing membrane interlayer (SAMI) on these stresses is examined
and compared with the case for the overlay placed directly on the cracked pavement.
