Property erosion in SBS modified binders during storage

Property deterioration during storage at elevated temperatures is one of the main concerns with SBS modified binders. Sumit et. al. have recently shown that significant loss in conventional and rheological properties takes place within the first 3 days of storage at 180 °C in polymer modified binders with 3 % to 6 % SBS polymer. In this study, we focus on evaluating the effect of various additives; such as waxes, antioxidants, aromatic oils, sulphur, oxidized binder, PPA and waste engine oil, on the property erosion in SBS modified binders during storage. Studies were carried out by storing the samples in aluminium storage tubes at 150 ºC and 180 ºC for up to 21 days. After the required storage time; softening point, elastic recovery and rheological properties of the SBS modified binders were measured. Waxes, such as finawax and sasobit seem to reduce the extent of drop in properties of PMBs. Our study clearly shows that other additives have negligible influence on the thermal stability of SBS modified binder.
