| 20220135802 | ASPHALT MODIFIER COMPOSITION AND RUBBER-MODIFIED ASPHALT HAVING INCREASED STORAGE STABILITY - Asphalt modifier packages and rubber-modified asphalts including the packages are described. Asphalt modifier packages can include an amine functionalized wax and an elastomeric polymer in conjunction with ground tire rubber. Asphalt modifiers can include a ground tire rubber compounded with a reactive elastomeric terpolymer. Rubber-modified asphalts can exhibit an excellent stability of the ground tire rubber additive. Rubber-modified asphalts can exhibit a storage stability separation factor of about 6° F. or less, an MSCR J | 05-05-2022 |
