MANUFACTURING METHOD AND MANUFACTURING DEVICE OF RECYCLED ASPHALT MIXTURE
To be able to restore flexibility and improve fatigue durability of deteriorated old asphalt.SOLUTION: A recycled asphalt mixture manufacturing device 1 classifies by a sieve 2 asphalt recycled aggregates into first recycled aggregates a with relatively large particle sizes of 13 mm to over 5 mm and second recycled aggregates b with relatively small particle sizes of 5 mm to over 0 mm. The first recycled aggregates a are put into a granulator 3 to separate parts of the old asphalt on the surface of the recycled aggregates. After that, with a sieve 4, the aggregates are classified into third recycled aggregates ab with relatively large particle sizes of 13 mm to over 5 mm and fourth recycled aggregates bb with relatively small particle sizes of 5 mm to 0 mm. The fourth recycled aggregates bb and the second recycled aggregates b, which have the same small particle sizes, are mixed, further, asphalt mortar is manufactured by mixing at least either new asphalt, or recycling additive d, or workability improving agent e. And asphalt mixture is manufactured by further mixing the third recycled aggregates ab.SELECTED DRAWING: Figure 1
【課題】劣化した旧アスファルトの柔軟性を回復させて疲労耐久性を向上できる。【解決手段】再生アスファルト混合物の製造装置１は、アスファルト再生骨材を篩２によって比較的粒径の大きい粒径１３ｍｍ〜５ｍｍ超の第一の再生骨材ａと比較的粒径の小さい粒径５ｍｍ〜０ｍｍ超の第二の再生骨材ｂとに分級する。第一の再生骨材ａを整粒機３に投入し、再生骨材の表面の旧アスファルトの一部を分離する。その後、篩４によって比較的粒径の大きい粒径１３ｍｍ〜５ｍｍ超の第三の再生骨材ａｂと比較的粒径の小さい粒径５ｍｍ〜０ｍｍの第四の再生骨材ｂｂとに分級する。同程度に粒径の小さい第四の再生骨材ｂｂと第二の再生骨材ｂとを混合し、更に新アスファルトと再生用添加剤ｄと施工性改善剤ｅの少なくともいずれかを混合することでアスファルトモルタルを製造する。更に第三の再生骨材ａｂを混合してアスファルト混合物を製造する。【選択図】図１
