Method for producing asphalt from mineral mixture and bitumen for constructing asphalt road in structural and civil engineering application, involves dewatering mixture by heating using microwaves, and mixing mixture with hot bitumen

摘要

The method involves dewatering a mineral mixture by heating using microwaves. Multiple fractions of the mineral mixture are specifically heated in a continuous furnace. The fractions of the mineral mixture are formed different according to a grain size. The continuous furnace is provided with multiple heating regions, which are heated by the microwaves. The mineral mixture is screened after heating. The mineral mixture is subsequently mixed with hot bitumen. The mineral mixture is initially stored in an intermediate storage.
