Abstract

The compatibility between 2 modifiers Styrene-Butadiene-Styrence Block Copolymer (SBS) and Sasobit and 70#A base asphalt was comparatively studied by means of solubility calculation, measurement of difference of segregation softening point, differential scanning calorimetry and atomic force scanning microscope. The results show that the solubility parameter can not reflect the influence of molecular weight on polymer compatibility, due to the asphalt and modifiers all have multiphase structures with high molecular weight, a complex structure should be expected for the bland of the asphalt and a modifier. The compatibility of the modified asphalt can not be simply evaluated as a whole by Hildebrand theoretical calculation formula. Adding Sasobit into base asphalt can not only increase the glass transition temperature of the base asphalt, but also change the shape of its endothermic peak curve significantly, so Sasobit has good compatibility with base asphalt. However, adding the two modifiers SBS and Sasobit can greatly reduce the compatibility between modifier and base asphalt.

Key words: inorganic non-metallic materials Sasobit warm mix asphalt compatibility solubility parameter atomic force microscope
