Abstract

Fatigue cracking is perceived as one of the primary failures in ASPHALT PAVEMENTs. This type of failure originates from the bottom of ASPHALT layer and then spreads upward as a result of repeated loading. Emersion of this type of cracks is common in ASPHALT sections with less thickness. In this research, for a better understanding of the mechanisms and parameters of fatigue cracks propagation, the FRACTURE MECHANICS approach was used. Subsequently, the crack phenomenon and its extension in PAVEMENTs were theoretically analyzed under three temperatures: low, medium, and high. The results showed that the stress intensity factor is directly correlated with the distance of loading from the center of the crack. Moreover, stress intensity factor was observed to increase more rapidly when the load is applied near the crack in case of having granular base compared to concrete base. This highlights the high impact of type of base, especially granular base, when it comes to changes in stress intensity factor.
