Asphalt composition comprising humins obtained from dehydration of carbohydrates

Abstract

An asphalt composition comprising aggregates and a binder material, wherein the binder material comprises humins, which humins comprise carbonaceous water-insoluble by-products of the dehydration of carbohydrates and/or 5-hydroxymethylfurfural and/or ethers or esters of 5-hydroxymethylfurfural. The invention also provides a binder material for use in asphalt compositions comprising from 1 to 95% wt, preferably from 5 to 60% wt of such humins, based on the weight of the binder material. The invention further provides for the use of such humins in the manufacture of binder material for asphalt compositions and the use of such humins as binder material in asphalt compositions.
