PROBLEM TO BE SOLVED: To provide an additive which suppress decrease in hardening at the temperature of releasing the road while having the effect of softening asphalt, and also prevents poor appearance such as whitening.SOLUTION: An asphalt workability improvement agent consist of ester of neopentyl polyol having two or three hydroxyl groups and 8-22C monohydric fatty acid. The agent may be added at any stage as long as asphalt is flowable by heating; however, it is added at the time of producing asphalt mixture.SELECTED DRAWING: None
【課題】アスファルトを軟化させる効果を持ちながらも道路を開放する温度での硬化低下を抑制し、白化等の外観不良を起こさない添加剤を提供する。【解決手段】アスファルト用施工性改善剤は、２個または３個の水酸基を有するネオペンチルポリオールと、炭素数８〜２２の1価脂肪酸とのエステルからなり、アスファルトを加温して流動性を持たせた状態であれば、いずれの段階で添加してもよいが、通常、アスファルト合材を製造する時に添加する。【選択図】なし
