摘要

In this paper, the combined use of reclaimed asphalt pavement (RAP) and rejuvenators for producing hot recycled asphalt mixture is investigated based on the new Bitumen Typisierungs Schnell Verfahren - BTSV method (Binder-Fast-Characterization-Test), recently proposed in Germany, and through laboratory experimentation. For this purpose, a set of three different asphalt mixtures is prepared with different amounts of RAP and with three types of rejuvenators. Then, the BTSV method is used to obtain the rheological properties of the binder extracted from the mixtures. Resistance to permanent deformation, stiffness, fatigue and low temperature behaviour are evaluated to determine the material response. It is observed that the combined use of RAP and rejuvenators results in mechanical properties are comparable to mixtures prepared with virgin material, confirming the validity of BTSV in determined the rejuvenator's proportions. These findings suggest the possibility of using rejuvenators for field applications.
