The aim of the invention is to create a method for reusing reclaimed asphalt, which is environmentally friendly in conventional systems, increases the reutilization rate of reclaimed asphalt when producing hot mixed asphalt products, and reduces the amount of new material used, such as minerals and binder/bitumen. Said aim is achieved by adjusting the high degree of hardness of the bitumen in the reclaimed asphalt, which is due to the age of the bitumen, by means of a softener while adding a hardener in combination therewith. Said softener-hardener system is added to a mixture containing reclaimed asphalt, primarily in the hot phase of the mixture.
