摘要

A system for the preparation of a chemical mixture, in particular of an asphalt mixture, with a paraffin content has a paraffin melt - and - metering device (33) with a dosing unit in order to promote an adjustable of paraffin which separates out is made of a paraffin tank (17) into a material component of the mixture, an input device for presetting a desired paraffin content in the mixture, and - a control and / or closed-loop control device for adjustment of the of the paraffin melt - and - metering device paraffin dose to be discharged as a function of the conveyed amount of the material component of the mixture and of the inputted paraffin content on. In this way, a quantities - preferred features. By means of a premature paraffin is added in a binder component at the entrance of a considerable energy saving potential. A fast and flexible applicability is (36) by means of a modular design of the paraffin melt - and - metering device is achieved.
