Essay

Road oil bitumens with and without surfactant. Used the methods of rotational viscosimetry (devices PVR-2 and Volorovich), method of Rebinder and the method of thin filament (microRHEOTESTER). Developed the calculation method to define the brittleness temperature. Experimentally proved that more equiviscous temperature is the middle of plasticity interval temperature, but not the softening point temperature. Established the correlation of critical temperature change of surface tension with the temperature change of bitumen from non-newtonian to newtonian flow. Proposed express-method to define the grade of bitumen.
