| 摘要 |
<p>The present invention relates to a method of heating and melting asphalt materials and asphalt mixtures by electromagnetic radiation wherein the needful heat arises inside a mixture or material by the action of a radiator being represented by an electromagnetic radiation source with operating frequency within the MHz and GHz bands. The asphalt mixture or the asphalt material (8) is placed directly in a space of a waveguide (3) being provided with a radiator (1) where heating or melting thereof takes place. In another possible embodiment, the waveguide (2) and the radiator (1) are located above the asphalt mixture or asphalt material (8) and electromagnetic radiation is directed through the waveguide (2) and heating or melting thereof takes place outside the system.</p> |
