Abstract

A method for generating a local polymer concentration (“LPC”) asphalt shingle coating is described. The method includes receiving a plurality of saturated polymer (“SP”) premix components including a rapid digestion process (“RDP”) compound and a sulfur cross-linking agent. The RDP compound is one or more of an unmodified RDP compound, a modified RDP compound, an enhanced RDP compound, and a modified enhanced RDP compound. The SP premix components are then heated in the first vessel to 320-500° F. and mixed for 15-60 minutes to generate a SP premix. The method also includes receiving an asphalt feedstock and a cross-linking polymer in a second vessel. The asphalt feedstock and cross-linking polymer are heated in the second vessel to 320-500° F. and mixed for 1-60 minutes to generate a LPC premix. The method proceeds by receiving the SP premix and the LPC premix in a third vessel and heating the SP premix and LPC premix to 320-500° F. with mixing for 30-240 minutes to generate the LPC asphalt shingle coating.

Abstract

A first method for generating a solubilized tire rubber bitumen compound is described. The first method begins by heating a first bitumen compound and a tire rubber compound to generate a bitumen wetted tire rubber mixture. The method includes adding a second bitumen compound to the bitumen wetted tire rubber mixture to generate a fully wetted tire rubber bitumen mixture. The method then proceeds to generate a devulcanized fully wetted tire rubber bitumen mixture, which is heated with mixing to between 500° F. and 700° F. to generate the solubilized tire rubber bitumen compound. Additionally, a second method for generating a solubilized tire rubber bitumen compound is described. The second method includes heating a first bitumen compound and a tire rubber compound to generate a devulcanized tire rubber bitumen mixture. The devulcanized tire rubber bitumen mixture is heated to generate a bitumen wetted devulcanized tire rubber mixture. Then, a second bitumen compound is added to generate a fully wetted devulcanized tire rubber bitumen mixture, which is heated to between 500° F. and 700° F. to generate the solubilized tire rubber bitumen compound.
