发明名称 Sulfur extended asphalt modified with crumb rubber for paving and roofing
摘要 This invention relates to asphalt compositions. The invention provides a sulfur rubber asphalt binder composition that includes a base asphalt having a softening point, elemental sulfur, and a crumb rubber material. The crumb rubber material is combined with the base asphalt and the elemental sulfur to create the sulfur rubber asphalt binder composition. The crumb rubber material is present in the sulfur rubber asphalt binder in an amount effective to increase the softening point of the composition as compared to the softening point of the base asphalt.
