Super-hydrophobic and super-oleophilic surface based on high-density polyethylene/styrene–butadiene–styrene block copolymer/waste ground rubber tire powder thermoplastic elastomer (TPE) was successfully prepared while metallographic sandpaper was used as a template. Field emission scanning electron microscope study showed that the molded TPE surface with W7 grade sandpaper possessed the rough microstructure; moreover, the micrometer scale strips resulting from the plastic deformation of TPE matrix could be observed obviously, leading to the increasing surface roughness. Wettability tests showed that the molded TPE surfaces with series sandpapers exhibited the hydrophobic and super-oleophilic properties; moreover, the surface molded with W7 grade sandpaper showed the remarkable super-hydrophobic and super-oleophilic properties.

This work presents the results of optimization compositions of polymer-modified binder (PMB) by a compromise task. The conducted study of influence two prescription factors – containing styrene-butadiene-styrene and sulfur – on which is a set of indicators of polymer-bitumen binders were carried out. The regularities of these factors of mutual influence were established by such indicators as the Fraas brittleness temperature, penetration, softening point, ductility. The dosages of SBS and sulfur have been determined by ensuring the achievement of the required level of PBB indicators in accordance with GOST R 52056-2003 «Bitumen-polymer road binders are based on styrene-butadiene-styrene block copolymers.
