    摘要: The invention relates to a method for producing a binder foam for producing asphalt. In a pressurized stream of heated binder, preferably bitumen, a liquid, which has a lower evaporation temperature under atmospheric pressure than the temperature of the heated binder stream, preferably water, is injected at an angle (α) of greater than 90° relative to the flow direction (S) of the binder stream such that a pressurized mixture stream of the binder with drops of liquid distributed therein or with drops of liquid distributed therein and vapor bubbles resulting from said drops is provided downstream of the injection point (D). The pressure of said mixture stream is then decreased, preferably to the atmospheric pressure, whereby the binder is foamed as a result of an evaporation of the drops of liquid contained in the binder and/or as a result of the expansion of the vapor bubbles resulting from the drops of liquid.
