Thermomechanical and microstructural evaluation of hybrid rubberised bitumen containing a thermoplastic polymer

The capability of modification of the polymeric additives were established as follows: SBS > EBA > EVA > EPDMs. The Hybrid System containing SBS (HS-SBS) presented, by far, the best overall performance due to the development a continuous SBS-rich network structure as a consequence of sulphur crosslinking reactions.
