ADDITIVE FOR RECYCLED ASPHALT, RECYCLING ASPHALT, RECYCLED HEATING ASPHALT MIXTURE AND PAVEMENT BODY
PROBLEM TO BE SOLVED: To provide an inexpensive and safe additive for recovering penetrability and extensibility of an aged asphalt binder, since an aliphatic system is not sufficiently recovered in extensibility when repeatedly recycled and an aromatic system is uneconomical due to requiring an addition quantity much for attaining penetrability, when classified into the aliphatic system and the aromatic system as such an oil component, though flexibility (penetrability and extensibility) is recovered by adding an additive mainly composed of an oil component for recycling the aged asphalt binder.SOLUTION: An additive for recycled asphalt is mainly composed of an aromatic system (C9 system) petroleum resin and grease.SELECTED DRAWING: None
【課題】 老化したアスファルトバインダーを再生するためにオイル成分を主体とした添加剤を加えることにより柔軟性（針入度及び伸度）を回復させることが行われている。かかるオイル成分としては、脂肪族系のものと芳香族系のものに分類され、脂肪族系のものは繰り返し再生を行った場合伸度が十分回復せず、芳香族系のものは針入度を達成するには添加量を多くする必要があり、不経済であった。そこで、劣化したアスファルトバインダーの針入度や伸度を回復させる安価で安全な添加剤を提供する。【解決手段】 再生アスファルト用添加剤としては、芳香族系(Ｃ９系)石油樹脂及び油脂を主成分とするもの。【選択図】 なし
