STABILISING ADDITIVE FOR PEAT-BASED ASPHALT-CONCRETE MIXTURE (VERSIONS) AND METHOD OF PRODUCING STRUCTURE-FORMING AGENT THEREFOR Russian patent published in 2013 - IPC C04B26/26 C08L95/00 

FIELD: chemistry.

SUBSTANCE: invention relates to production and application of stabilisers of macadam-mastic asphalt-concrete and asphalt-concrete mixtures for road surfaces. The stabilising additive for macadam-mastic asphalt-concrete mixture contains a natural fibrous structure-forming agent and bitumen. The structure-forming agent used is the medium fibrous humus-bitumen fraction from ground dry peat with particle size of not more than 2.5 mm and an adhesion additive is added, with the following ratio of components, wt %: said ground peat 50…100, adhesion additive 0…50. Also described is a version of the stabilising additive and a method of producing a structure-forming agent from peat.

EFFECT: production of a stabilising additive for macadam-mastic asphalt-concrete and asphalt-concrete mixtures, which provide high characteristic values of the road surface at a low cost and easier production thereof using abundant cheap material.
