摘要

A process for the preparation of a bituminous material to be mixed, in particular, asphalt, preferably chippings mastic asphalt material for road surfaces, and comprising the steps of:– Premixing of minerals with the addition of additives,– subsequent wet mixing with the addition of the binder, such as bitumen and– final remixing, wherein the additives are at least one as a carrier substance for fischer tropsch - - paraffin (ft - paraffin) are configured in the cellulose fibers, characterized in thata) in the pre-mixing time pressed articles (1) with at least portions of cellulose fibers (2) - and ft paraffin (3) are added to the minerals,b) in the pre-mixing time the pressed articles (1) through the mechanical comminuting action of the minerals and rubbed in this case, the cellulose fibers (2) with the ft - paraffin (3) in the mineral mixture already largely be distributed, after which, in the following wet mixing time of the homogeneous distribution is secured in the bitumen,c) the result of the: 230.6– the of the standardized types of selected output - bitumen of the material being mixed in a reduction of the needle penetration of at least two standardized types and the low temperature behavior is subjected to practically..
