ADDITIVE FOR ASPHALT, ASPHALT MIXTURE, ROOFING MATERIAL AND PAVEMENT BODY
To provide an additive for asphalt which can suppress deterioration with time when used in a pavement body or a roofing material.SOLUTION: There is provided an additive for asphalt which contains a base oil (A) having a kinematic viscosity at 40°C of 50 cSt or more and 500 cSt or less and a neutral phosphite ester derivative represented by the following formula (B) as an additive. In the formula (B), Rb21 to Rb24 each independently represent an aliphatic hydrocarbon group having 10 to 16 carbon atoms, Rb25 to Rb28 each independently represent a linear or branched alkyl group having 1 to 6 carbon atoms, Rb291 and Rb292 each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 5 carbon atoms and the total number of carbon atoms of Rb291 and Rb292 is 1 to 5.SELECTED DRAWING: None
【課題】舗装体またはルーフィング材に用いた際に、経時的な劣化が抑えられるアスファルト用添加剤を提供すること。【解決手段】アスファルト用添加剤は、４０℃における動粘度が５０ｃＳｔ以上５００ｃＳｔ以下である基油（Ａ）と、添加剤として下記式（Ｂ）で表される中性亜リン酸エステル誘導体とを含む。式（Ｂ）中、Ｒb21～Ｒb24は、それぞれ独立に、炭素原子数１０～１６の脂肪族炭化水素基を表し、Ｒb25～Ｒb28は、それぞれ独立に、炭素原子数１～６の直鎖もしくは分枝状のアルキル基を表し、Ｒb291およびＲb292は、それぞれ独立に、水素原子または炭素原子数１～５の直鎖もしくは分枝状のアルキル基を表し、Ｒb291およびＲb292の炭素原子数の合計は、１～５である。【化１】TIFF2024090026000014.tif36170【選択図】なし
