SBS-modified, asphalt-based material with resistance to crosslinking |
摘要 |
An asphalt material, useful for forming a membrane, comprises a mixture of from about 47 to about 74 parts by weight of asphalt, from about 7 to about 15 parts by weight of styrene-butadiene-styrene block copolymer, from about 15 to about 25 parts by weight of a filler component, and from about 1 to about 5 parts by weight of polypropylene homopolymer. A method for preparing a modified-asphalt material comprises the steps of forming a mixture by admixing from about 47 to about 74 parts by weight of asphalt; from about 7 to about 15 parts by weight of a styrene-butadiene-styrene block copolymer; from about 15 to about 25 parts by weight of a filler; and from about 1 to about 5 parts by weight of a polypropylene homopolymer; wherein the polypropylene homopolymer inhibits high temperature crosslinking of the styrene-butadiene-styrene block copolymer.
