MSCR PLASTOMER-MODIFIED ASPHALT BINDERS MEETING MSCR SPECIFICATIONS ASPHALT PAVING MATERIALS WITH SUCH ASPHALT BINDERS AND METHODS FOR FABRICATING SUCH ASPHALT BINDERS

摘要

The present invention provides a plastomer-modified asphalt binder satisfying the MSCR standard, an asphalt packaging material having the asphalt binder, and a method of manufacturing the asphalt binder. The asphalt binder contains a base asphalt and a plastomer. When the plastomer has an adduct temperature of about 139 占 폚 or lower, the asphalt binder may contain sulfur; Sulfur-containing compounds such as hydrocarbyl disulfide and thiuram disulfide; Phenolic resin; Metal oxides; Or a combination thereof. The asphalt binder is substantially free of elastomer.
