Abstract: 
A concept for the evaluation of the fracture behaviour of asphalt bituminous pavements with an overlay system is presented. In this concept, both the bonding of the interlay with the asphalt layers, as well as the propagation of reflection cracking are determined on drilling core specimens. Test results on three overlay systems already used in practice (PGM 14, PGM-G and TENSAR grid) are reported. Based on these results, the factors influencing the fracture behaviour are analysed and discussed. The fracture behaviour is influenced by various factors, with the bonding between interlayer and asphalt layers being the most important one. This effect is quantified by the determination of the resistance of the systems against propagation of reflection cracking.
