MINERAL POWDER FOR BITUMINOUS CONCRETE Russian patent published in 1999 - IPC

Abstract RU 2125547 C1

FIELD: road pavements. SUBSTANCE: powder, in addition to mineral component, contains 0.8-1.5 wt % of alkyl sulfate production residue (domestic synthetic detergents production) and 1.0-2.0 wt % of heavy goudron. Such composition results in reduced (by 0.3-0.6%) swelling, high water repellency, and reduced (by 0.3-1.2%) consumption of bitumen in bituminous concrete production with simultaneous increase in water resistance of bituminous concrete. EFFECT: enhanced efficiency of bituminous concrete production process. 2 tbl, 8 ex
