METHOD OF PRODUCING LIQUID BITUMEN MATERIAL Russian patent published in 2016 - IPC C10C3/00 C08L95/00 

FIELD: construction.

SUBSTANCE: invention relates to road construction, specifically to production of liquid bitumen materials which can be widely used as binding materials for construction, repair, waterproofing, mounting and other kinds of work. Method involves mixing initial bitumen and thinner in form of gas-oil petroleum fraction with boiling end temperature of 385-400 °C and pour point not higher than 0 °C. Mixing is carried out at temperature of bitumen not lower than 130 °C and thinner not higher than 40 °C in flow static mixer with opposite feeding of components to ensure mechanical activation of mixture and in following ratio of components, wt%: source bitumen - 40-98, thinner - 2-60.

EFFECT: technical result is higher resistance to breakdown of mixture during prolonged storage.
