Patent number: 9102834Abstract: A method for producing bulk good of agglomerates made of rubber particles and wax. A composition of the agglomerate and the use of the bulk good to produce asphalt or bitumen masses are created in that rubber is activated by swelling and using a swelling agent and a melt made of viscosity-reducing wax and of optional polyoctenamer is added, the activated rubber particles are agglomerated by means of the viscosity-reducing wax and optional adhesion-improving substances. The resulting larger volume leads to a viscosity reduction and the softening leads to a more intimate and more homogeneous wetting with the wax and, in the mixed good to be produced, a viscosity reduction remaining stable in the mixed good for <180 min and an increased stability of the cross-linking of the rubber molecules among each other after the agglomerates have been incorporated are achieved.Type: GrantFiled: July 10, 2011Date of Patent: August 11, 2015Assignees: SASOL WAX GmBH, STORIMPEX IM-UND EXPORT GmBHInventors: Thorsten Butz, Matthias Nölting, Gunnar Winkelmann
