Publication number: 20180112074Abstract: This invention provides for a method for producing polymer modified asphalt using base asphalt (bitumen) blended with partially air blown (“puffed”) asphalt which is further modified with polymers and additives to attain desired properties for industrial applications. The partially blown or blown asphalt is oxidized to a target softening point to suit the application. In another embodiment, the base asphalt is blended with hard PEN asphalt (“Zero PEN Asphalt”) which is further modified with polymers and additives to attain desired properties. By using the partially oxidized asphalt or blending the base asphalt with partially oxidized asphalt or hard PEN asphalt, the amount of polymers and additives needed to achieve desired properties and performance are significantly reduced. This technique can be used to attain polymer modified asphalt having a highly desirable combination of characteristics not otherwise attainable using the base asphalt.Type: ApplicationFiled: October 6, 2017Publication date: April 26, 2018Applicant: Building Materials Investment CorporationInventor: Denis Muki Tibah
