Recycling rubber waste contributes to a cleaner environment by using indestructible rubber discards as well as lowering production costs as reclaimed rubber is cheaper than virgin or natural rubber. Therefore, in this study, the properties of recycled acrylonitrile butadiene rubber glove (NBRgr) blending with styrene butadiene rubber (SBR) has been determined. The effects of SBR/NBRr blends on properties of such fourier transform infrared (FT-IR) and morphology properties were carried out. FT-IR analysis showed that SBR/NBRr R05 blended with the smallest size NBRr (S1) and showed most intense amine absorption at 1535 cm-1.The intensity decreased by increasing the NBRr sizes. By incorporating the smallest size NBRr provided more surface area to interact with SBR polymers thus increased the level of crosslink. From scanning electron microscopy (SEM) observation on fatigue failure surface, the SBR/NBRr blended with the finest size of NBRr (S1) showed roughest matrix tearing compared to S2 and S3 indicated better fatigue propagation. At higher blend ratio (50/50), the SBR/NBRr blended with S2 and S3 exhibited a coarser and a poorer distribution of NBRr with SBR matrix which led to lower fatigue life.

Bitumen Modification

The study described in this paper focused on the possible use of waste products coming from the production of styrene–butadiene rubber (SBR) and polybutadiene rubber (PBR), as bitumen modifiers. Modified binders containing these products were prepared in the laboratory with different polymer dosages and were thereafter subjected to the evaluation of empirical and rheological properties. For comparative purposes, the study also considered SBR and PBR products of premium quality. Ageing effects were also taken into account by means of proper laboratory simulations. Obtained results indicated that the two types of polymer (SBR and PBR) have completely different effects on the rheology and expected performance of the resulting modified binders. In particular, while the two polymers showed similar effects in terms of resistance to permanent deformation, the SBR products proved to be superior from the viewpoint of fatigue resistance. However, only minor differences were found when comparing the effects produced by premium quality and waste polymers. As a result of the experimental findings, it was concluded that the use of waste SBR polymers can be an attractive solution for the production of affordable modified binders.
