FRACTURE MECHANICS APPROACH TO CRACKING IN PAVEMENTS
The conditions under which material undergoes slow crack growth are of paramount importance in pavement cracking. Recent studies indicate that microscopic crack extension can occur at subcritical values of stress intensity factor, K, but that the process is self-limiting. When K attains its critical value K sub c, the crack propagates spontaneously. The damage process associated with cracking, due to either environmental factors or load repetition, is discussed in this paper. The mechanics of reflection cracking is also examined in the light of fracture mechanics principles.
