COMPOSITION OF BINDER FOR PREPARATION OF ASPHALTIC BITUMEN MIXTURE Russian patent published in 2010 - IPC C04B26/26 

FIELD: construction.

SUBSTANCE: invention is related to compositions of binding material for preparation of asphaltic bitumen mixes and may be used in erection, reconstruction and repair of transport structures with hard surface. Composition of binder for asphaltic bitumen pavements, including the following components, wt %: bitumen 41-43, Sulfur 54-56, mineral oil 2.1-2.35, lime 0.1-0.6, hydroxide of trivalent iron 0.2-0.5, carboxymethylcellulose 0.02-0.03, polymer 0.02-0.08. Composition provides for increase of surface softening temperature by 5-11°C, reduction of brittleness temperature by 4-7°C, increased strength and service life.

EFFECT: increased temperature of asphaltic concrete softening temperature, reduced temperature of its brittleness and, as a result, increased service life, and also elimination of ecological and corrosion problems.
