Nanomodified Polymer-Bitumen Binders

A modification of petroleum bitumen for road building was carried out by devulcanizing rubber crumb and adding modified dispersion, consisting of single-walled carbon nanotubes (SWCNT), distributed in industrial oil (I-20A). It was found that the particle size after sonication became significantly smaller. In this case, the optimal dispersion time was 10 minutes, because further ultrasonic exposure was not accompanied by a change in particle size, according to the HoribaLA-95 laser analyzer. It has been experimentally determined that the optimal wavelength for measuring optical density and transmittance is λ=430 nm. It was found that the introduction of nanotubes plasticizes the binder. In this case, the introduction of SWCNTs increases its hardness. It was also noted that the effect of the dispersed phase on the properties decreases with the introduction of nanotubes.
