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 ar different linked together by an ester, carbon or ether bond, said unit having the following formula: CH3-(C n H2n)-R1 wherein: n is 4 or more, and R1 is COON, 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.
