Description: The effect of modification of tar by iron (III) stearate on the rate of the oxidation process and the quality of oxidized bitumen has been studied. The dependences of the softening temperature of bitumen upon the oxidation time, the dynamic viscosity of bitumen on the temperature have been obtained. Penetration, penetration index, group composition and thermal-oxidative stability of oxidized bitumen modified by iron (III) stearate have been determined. It was determined that small quantities of a modifier (up to 1.5 wt %) in the raw material don’t influence the rate of oxidation, and with increasing content of the modifier in the raw material the rate of the process is increased by 1.6–4.0 times.
