摘要：
In a method for the production of a plant-mixed asphalt mix for paving purposes by mixing a batch of bituminous binder and a batch of mineral aggregate in a mixer at a temperature at which the binder has a viscosity of at least 150 cSt, the batch of mineral aggregate containing both particles above 2 mm and particles within the range of 2-0.5 mm and also smaller particles, the batch of mineral aggregate is divided into a first and a second part in such a way that said second part contains particles of said mineral aggregate batch within the range 2-0.5 mm, and said first part of the mineral aggregate batch is first mixed with the binder batch before said second part of the mineral aggregate batch is introduced into the mixer.
