A method of producing an improved asphalt comprising:
- providing an asphalt binder;
- providing a compound of formula (I):
- wherein:
- each A is selected independently at each occurrence thereof from the group consisting of
- and
- wherein at least one A is
- n=1-12;
- each
- represents the point of attachment to a —CH2— group;
- R is selected from the group consisting of C3-C23 alkyl and benzyl, wherein the C3-C23 alkyl can be optionally substituted with an aryl, heteroaryl, or heterocyclyl;
- R1 and R2 are independently selected from the group consisting of H, C1-C23 alkyl and benzyl, wherein the C1-C23 alkyl can be optionally substituted with an aryl, heteroaryl, or heterocyclyl, wherein the compound of formula (I) is selected from the group consisting of epoxidized benzyl soyate and epoxidized isoamyl soyate and
- mixing the asphalt binder with the compound of formula (I) under conditions effective to produce an improved asphalt.
