The effect of bitumen conforming to the requirements of GOST 22245-90 and unusable bitumen with polymer sulfur in different
mass ratios was studied and the optimal conditions were determined. Physico-mechanical properties of modified sulfur bitumen
were studied. Chemical substances were used in sulfur modification. Chemical substances were used in the modification of
sulfur. After obtaining sulfur bitumen, its composition was studied and compared with ordinary bitumen. As a result of research,
it was found that adding sulfur to the bitumen in the amount of 20% and 30% significantly improves the properties of the
obtained sulfur bitumen.
