Asphalt compositions for roofing applications, methods for making the same, and filled asphalt material comprising the same

Asphalt compositions for roofing applications are provided, as well as filled asphalt material comprising the asphalt compositions and methods for making asphalt compositions and filled asphalt material. More particularly, the asphalt compositions 5 comprise non-oxidized base asphalt; and a low molecular weight polyolefin present in an amount of from about 0.5 to about 15 wt % based on the total weight of the asphalt composition. The asphalt composition has a softening point from about 87.8 to about 160 DEG C (about 190 to about 320 DEG F), a penetration of greater than 12 deci-millimeters DEG @ 25 DEG C, as well as improved stain resistance and heat resistance. 提供用于铺顶应用的沥青组合物，以及包含所述沥青组合物的填充型沥青材料和用于制备沥青组合物和填充型沥青材料的方法。更具体地，所述沥青组合物包含非氧化基料沥青；和基于沥青组合物总重量以约0.5至约15 wt %的量存在的低分子量聚烯烃。所述沥青组合物具有约87.8至约160℃ (约190至约320 °F)的软化点、大于12丝米的针入度@ 25℃、和改善的耐污斑性和耐热性。
