Process for the manufacture of a bituminous mixed material, pressed piece for use according to the procedure and bituminous mixed material for covering roads.

摘要

The logistics of incorporating FT paraffin into bitumous mixtures is improved and the techniques used for production and incorporation are rationalized. To achieve this, pressed items (1) containing at least partially cellulose fibres (2) and FT paraffin (3) are added during a pre-mix period of the bituminous mixtures that are to be produced. Said items are essentially distributed while the minerals are pre-mixed and ensure that the FT paraffin is mixed into the bitumen during the wet mixing period, whereby, in the post mixing phase, conditions for characteristics such as plastic deformations are met when incorporation into the mixture has occurred.
