Asphalt compositions, asphalt products made from such asphalt compositions, and the methods of making and using such compositions and products

Abstract

Paving compositions comprising asphalt cement, wherein the asphalt cement may have a with a pen value greater than 50 dmm at 25° C., and the composition may further include a an aminated wax, a rejuvenator and/or a polymeric component. Paving structures include a substrate pavement layer with a tack coat applied thereto, and methods of making a paving structure include applying a tack coat to a substrate pavement layer, wherein the tack coat comprises asphalt cement, wherein the asphalt cement may have a with a pen value greater than 50 dmm at 25° C., and the tack coat may further include a an aminated wax, a rejuvenator and/or a polymeric component.

1 . A paving composition comprising an aminated wax and an asphalt cement with a pen value greater than 50 dmm at 25° C. 
     
     
         2 . A pavement structure comprising:
 a substrate pavement layer;   a tack coat applied to the substrate pavement layer, wherein the tack coat comprises an asphalt cement with a pen value greater than 50 dmm at 25° C.   
     
     
         3 . A method of forming a pavement structure, comprising:
 applying a tack coat to a substrate pavement layer, wherein the tack coat comprises an asphalt cement with a pen value greater than 50 dmm at 25° C.
