Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an asphalt workability improver which improves workability by being added to asphalt to soften it and, even when the asphalt is stored at elevated temperature, causes little deterioration of a softening effect.SOLUTION: An asphalt workability improver is a compound represented by formula (1) in the figure. (In the formula (1), Rrepresents a C6-14 alkyl group or acyl group, AO represents a C2-4 oxyalkylene group, and x represents an integer from 1 to 5.)SELECTED DRAWING: None 【課題】アスファルトに添加して軟化させることで施工性を改善し、さらにアスファルトを加熱して保管しても軟化効果の低下が生じにくいような、アスファルト用施工性改善剤を提供する。【解決手段】アスファルト用施工性改善剤が、式（１）で示される化合物である。【化１】（式（１）中、Ｒ１は炭素数６〜１４のアルキル基又はアシル基を示し、ＡＯは炭素数２〜４のオキシアルキレン基を示し、xは１〜５の整数を示す。）【選択図】なし
