This invention discloses an
asphalt concrete that combines ice-breaking and
noise reduction with its manufacturing method, comprising the following raw materials by weight: 100-120 parts aggregate, 5-8 parts thermally conductive
asphalt, 2-8 parts mineral
powder, and 3-5 parts
noise-reducing filler. The aggregate,
noise-reducing filler, and mineral
powder are stirred for 20 seconds, then the thermally conductive
asphalt is added, mixed, and shaped to obtain the
asphalt concrete that combines ice-breaking and
noise reduction. Modified
silicon carbide is introduced into the thermally conductive asphalt, with carbon nanotubes as the
carbon source,
silicon powder and
silicon dioxide as the silicon source, and
cobalt acetate as the
cobalt source. Modified
silicon carbide is prepared by
solid-state
sintering, in which
cobalt atoms enter the
silicon carbide lattice to prepare cobalt-doped
silicon carbide. While silicon
carbide itself has excellent
thermal conductivity, the introduction of cobalt gives the modified silicon
carbide magnetism and improves its
microwave absorption performance. Under
microwave action, it can quickly melt
snow and break ice, and also improves the
thermal conductivity of the asphalt, further improving the ice-breaking performance.
