    • A Performance Grade sulfur-extended asphalt binder emulsion is made by combining a viscosifier, an emulsifier, a Performance Grade sulfur-extended asphalt binder, optionally a saponification agent, and a base aqueous solution. During creation of the asphalt emulsion, none of the components or combinations of them exceeds 275° F. The Performance Grade sulfur-extended asphalt binder composition is made by combining free or element sulfur, a linear alkane material, optionally a saturated-backbone polymer modifier, optionally a non-aqueous acid, and a base asphalt. The disclosed Performance Graded sulfur-extended asphalt binder and Performance Graded asphalt sulfur-extended asphalt binder emulsion allow operators using these products directly or in combination with aggregates and other materials to mix and blend the compositions, and apply the compositions in the field, at temperatures less than 300° F.
    • 通过将增粘剂,乳化剂,性能级硫磺延展沥青粘合剂,任选的皂化剂和碱性水溶液组合来制备性能级硫磺沥青粘合剂乳液。 在沥青乳液的制造过程中,没有一种组分或其组合超过275°F。性能等级的硫磺沥青粘合剂组合物是通过将游离的或元素的硫,直链烷烃材料,任选的饱和主链聚合物改性剂 ,任选的非水性酸和基础沥青。 所公开的性能分级硫磺沥青粘合剂和性能分级沥青硫磺延伸沥青粘合剂乳液允许操作者直接使用这些产品或与聚集体和其它材料组合以混合和混合组合物,并在本领域中应用组合物 小于300°F
