ASPHALT WORKABILITY IMPROVING AGENT
PROBLEM TO BE SOLVED: To provide an asphalt workability improving agent that has an effect of softening asphalt by added to asphalt, but yet suppresses the decrease of hardening at a temperature of opening the road, and does not cause poor appearance such as whitening.SOLUTION: The asphalt workability improving agent comprises an ester of an alcohol having 4 to 12 carbon atoms and having 4 to 6 valences and a monovalent fatty acid having 16 to 22 carbon atoms and having an esterification degree of 0.5 to 1.SELECTED DRAWING: None
【課題】アスファルトに添加することで、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は、炭素数4〜12かつ4〜6価のアルコールと炭素数16〜22の1価脂肪酸とのエステルであって、エステル化度が0.5〜1であるエステルからなる。【選択図】 なし
