摘要

From pavement's lifetime point of view one of the most relevant binder parameters is that parameter which can characterise the fatigue behaviour of the binder. This property can be measured at an intermediate temperature range, as the penetration according to conventional standards or as the G~*sinδ parameter prescribed by a performance related specification (SHRP). In our study we looked for a correlation between the above mentioned parameters and the fatigue J cycle-numbers determined from the classical fatigue curve (modulus vs. number of cycles), which I are applied in the asphalt mix mechanics already for a long time.
