Abstract
The highway network of Alberta is the major component of its infrastructure system which is difficult to be maintained. The first part of this study focuses on seasonal variation of pavement layers’ stiffness and its influence on the pavement life. Pavement structures are supposed to be in weakest condition during thawing period in early spring. The results shows that damage imposed to pavement during thawing period can be approximately 90% more than during the recovering period. The second part of the study centers on comparing the performance of different asphalt overlay strategies in the Province of Alberta. For this purpose, the data collected under Long Term Pavement Performance in Alberta Specific Pavement Studies 5 section was used. In addition, Mechanistic Empirical Pavement Design Guide software was used to simulate different overlay strategies. The results indicate that overlay thickness is the most influencing factor on the performance of the overlaid sections
