Asphalt products and methods of producing them for rejuvenation and softening of asphalt

An asphalt product comprising:

• an asphalt binder and
• 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,
• fiberglass, and
• a mineral aggregate.

A recycled asphalt pavement aggregate, wherein the improvement comprises an asphalt product comprising:

• an asphalt binder and
• 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.

A method of making an asphalt material comprising the steps of:

• (a) providing an improved asphalt product comprising:
• an asphalt binder and
• 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, mixed with the asphalt binder, wherein the improved asphalt product has a complex shear modulus reduction of between 67% to 96% compared to that produced when the improved asphalt material is prepared in the absence of the compound of formula (I);
• (b) mixing the improved asphalt product with a mineral aggregate to coat the mineral aggregate and produce a heated paving material which has a dynamic modulus reduction compared to that produced when the improved asphalt material is prepared in the absence of the compound of formula (I);
• (c) applying the heated paving material to a surface to be paved to form an applied paving material, and
• (d) compacting the applied paving material, to a void fraction of less than 8% to form a paved surface.
