The present invention relates to a method for the treatment with a liquid agent of an asphalt structure, in particular an asphalt structure which comprises a porous asphalt surface course, using an air flow directed at the aforesaid asphalt structure, wherein said treatment comprises the following steps:
i) spraying a liquid binder onto the surface course of the aforesaid asphalt structure;
ii) directing a concentrated air flow at the liquid binder sprayed onto the aforesaid surface course in step i), wherein step ii) is carried out in such a manner that the spraying according to step i) and the directing of the air flow according to step ii) are carried out as separate steps, so that the aforesaid liquid binder will penetrate through the surface course, forming a sealing layer of binder in the aforesaid surface course in a region near the bottom side of the surface course. |
