Bituminous material e.g. recycling asphalt, heating method for constructing e.g. road surface, involves isolating heat transfer body from bituminous material after mixing cold mixing material with hot additive

摘要

The method involves mixing a cold mixing material (24) with a hot additive in a mixer (23). The additive has a heat transfer body (14), which is isolated from the material after the mixing procedure in the mixer and after the heat transfer on the material. The body is heated after isolating from the material. The heat transfer body and a heat aggregate (11) are mixed with the material in the mixer. An independent claim is also included for a device for heating a bituminous material.
