ROAD BITUMEN CONCRETE BASED ON MODIFIED ASPHALT BINDER Russian patent published in 2014 - IPC C08L95/00 C09D195/00 C04B26/26 C09D1/10 

FIELD: construction.

SUBSTANCE: bitumen concrete mix includes crushed limestone of 0-5 mm grain size as mineral material, asphalt cement BND 90/130 as a binder, and mechanoactivated lignite as modification agent in the following component ratio, wt %: crushed limestone of 0-5 mm grain size - 93; asphalt - 6.3; mechanoactivated lignite - 0.7.

EFFECT: modification agent increases adhesion properties of crushed stone/binder system thus producing bitumen concrete with good mechanical properties and streamlining and accelerating mix preparation process.
