The present invention relates to a compatibalizing agent useful in compatibalizing a substantially non-polar compound, such as asphalt, with a substantially polar organic compound, such as an isocyanate prepolymer. The compatibalizing agent consisting of a polymer unit, or of two such units being either identical or different linked together by an ester, carbon or ether bond, said unit having the following formula: CH3－(CnH2n)－R1 wherein: n is 4 or more, and R1 is COOH, COO-M+, COOR2 or R2, wherein: M is a metal, and R2 is a substantially saturated organic chain having a backbone substantially comprising carbon-carbon, carbon-oxygen, or carbon-nitrogen linkages, or combinations thereof, wherein the backbone\s pendent constituents are either －H or －OH and wherein at least one pendent constitutent is －OH.
