(57) The invention refers to a method for producing an asphalt mix that includes a coarse
fraction, a fine fraction, filler and a bituminous liquid with the following steps
in the mentioned order:
a) mixing the coarse fraction and the bituminous liquid in a mixer,
b) discharging the filler to be spread over the coarse fraction and the bituminous
liquid and
c) discharging the fine fraction over the filler and mixing,
d) discharging the ready mix from the mixer,
wherein the discharge of the fractions are optimized so that the mix behaves like
a liquid in a test where a deformation of a specimen of the mix depending from the
temperature of the specimen is measured, as known from EP 0 756 615 B1.
For increasing the viscous resource in batch plant mixed asphalt pavings, the invention
teaches that, for conducting step a), the coarse fraction and the liquid binder are
discharged and mixed simultanously over a first time period. Further, devices for
carrying out such method are described.
