Physical properties and microstructure of bitumen highly-modified with ground tire rubber

Abstract

In this work, ground tire rubber was thermo-mechanically devulcanized in planetary extruder and subsequently was used for preparation of bitumen highly-modified with ground tire rubber. The physical and processing properties of prepared materials were characterized based on penetration, softening point and melt flow rate measurements. Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis and volatile organic compounds' emission level were used for assessment of interfacial interaction between GTR and bitumen.
