Abstract
Asphalt packets and methods of making and using asphalt packets are provided. For example, an asphalt packet can be provided that include asphalt that comprises an inner volume and a polymer film outer coating that encapsulates the inner volume of the asphalt. The polymer film outer coating can be non-tacky at ambient temperatures to permit stacking of a plurality of asphalt packets under weight without causing the packets to agglomerate.
Claims11
A process of making asphalt packets comprising:
- providing liquid asphalt;
- providing liquefied polymer;
- coextruding the asphalt and the polymer into an extrudate with the asphalt forming a core of the extrudate and the polymer forming an outer perimeter of the extrudate such that the polymer forms an outer surface of the extrudate;
- cutting the extrudate into asphalt packets having a surface area to volume ratio of 10 or greater.
1 more element
A process of making asphalt packets comprising:
- providing a bottom sheet of polymer and a top sheet of polymer;
- extruding liquefied asphalt between the top and bottom polymer sheets;
- cutting and sealing the top and bottom polymer sheets and asphalt together into asphalt packets comprising an asphalt inner volume and a polymer film coating outer surface having a surface area to volume ratio of 10 or greater.
