COMPOSITION FOR SURFACE TREATMENT OF ROAD CARPETS Russian patent published in 2009 - IPC E01C7/24 C04B26/26

Abstract RU 2364676 C1

FIELD: construction, road engineering.

SUBSTANCE: invention is related to road engineering, namely to composition for surface treatment of road carpets and may be used in construction and repair of motor roads. Composition for surface treatment of road carpets comprises binder in the form of bitumen emulsion including bitumen, emulsifier, inorganic acids and water, and filler containing Fe₂O₃. Filler used is slag broken stone from electric steel smelting production of Volzhskiy pipe factory with fractions of 10-15 mm of Fe₂O₃ content in amount of 14-21 % at mass ratio of bitumen emulsion to filler equal to 0.087-0.093.

EFFECT: improved technical performance characteristics of road carpet, increased service life, better ecology, lower prime cost of road surface.
