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.
