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 &#x3c;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.
