Abstract: Regarding lifetime prediction of pavement, crack propagation under dynamic and monotonic loading is of major interest. The aim of this work was to apply fracture mechanics to study the crack propagation in bituminous mixtures. The best way to characterise crack propagation in these materials appears to be the R curve calculated by the non linear fracture mechanics. Experimental R-curves shows that bituminous mixtures are more brittle at low temperature, or under fast loading. The effect of bitumen / stone ratio can be quantified and discussed. Acoustic emission shows that damage begins before the crack propagation, and is sensitive to damage during crack propagation. Acoustic emission depends also on the temperature of the material.
