<p>The present invention relates to an airport concrete pavement construction method using foam shotcrete, which comprises: a step of producing normal concrete with compression strength of 21-3- MPa in a batcher plant and transferring the normal concrete to a local site; a step of mixing foam of 20-40% to volume in order to increase fluidity, and mixing a low grade mixing material, where at least one or more among fly ash, slag fine powder, and ultra-rapid hardening clinker powder are mixed, in a mixing unit in order to form normal strength concrete; a step of performing shorting of the normal strength concrete in order to form the lower layer of airport concrete pavement; a step of mixing a high grade mixing material, where at least one or more among silica fume, metakaolin, ultra-rapid hardening clinker powder, latex, a polymer, and a coloring material are mixed into the normal concrete mixed with the foam, in the mixing unit in order to form high performance concrete; a step of performing shorting of the high performance concrete in order to consecutively construct the upper layer of the airport concrete pavement. Therefore, the airport concrete pavement construction method can facilitate maintenance by securing high strength and high durability, and can facilitate construction through weight lightening of a slip form paver by removing compacting of the shorting high performance concrete.</p> |
