Abstract (en)
Apparatus for production of asphalt mass, wherein the apparatus comprises a mixing device (10), a solids source (14), two bitumen sources (11, 12), a bitumen balance (16) having agitator, in flow connection with the mixing device (10) via conduit (25), an amine source (13), and a water source (15) for foaming of bitumen. A buffer container (17) is arranged in conduit (25) between the bitumen balance (16) and the mixing device (10) to receive apportioned bitumen. A mixing means with rotor (23) is arranged at the mixing device (10) in connection with a water source (15) and bitumen from the buffer container (17). The apparatus offers a high bitumen production rate.
