Abstract
An antistripping composition, comprising a first triamine compound or a second amine compound, and less than 1 wt % of a nitrile compound. When the antistripping composition is used in a bitumen composition, the bitumen composition demonstrates 50% or more retained coating as measured according to AASHTO T 283 (2022), and a tensile strength ratio of at least 80% when measured according to ASTM D 3625 (2020).
Claims20
An antistripping composition, comprising:
- a first triamine compound or a second amine compound;
- and
- less than 1 wt % of a nitrile compound;
- wherein, when used in a bitumen composition, the bitumen composition demonstrates 50% or more retained coating, measured according to AASHTO T 283 (2022);
- and
- a tensile strength ratio (TSR) of at least 80%, measured according to ASTM D 3625 (2020).
An antistripping composition, comprising:
- an amine compound comprising an alkane triamine or an alkene triamine or a combination thereof, and
- less than 1 wt % of a nitrile compound;
- wherein, when used in a bitumen composition, the bitumen composition demonstrates 50% or more retained coating, measured according to AASHTO T 283 (2022);
- and
- a tensile strength ratio (TSR) of at least 80%, measured according to ASTM D 3625 (2020).
An antistripping composition, comprising:
- from 10 wt % to 80 wt % of a first triamine compound comprising BHMT;
- from 10 wt % to 80 wt % of a second amine compound comprising an alkane triamine or an alkene triamine or a combination thereof;
- from 2 wt % to 20 wt % of an organic additive comprising ethanol, propanol, or an alkylene glycol, or corresponding esters of thereof, or combinations thereof, and
- less than 1 wt % of a nitrile compound.
An antistripping composition, comprising:
- a first triamine compound comprises BHMT or a second amine compound comprises triaminononane;
- and
- less than 1 wt % of a nitrile compound;
- wherein, when the antistripping composition is used in a bitumen composition from 0.1 wt % to 5 wt %, the bitumen composition demonstrates 50% or more retained coating, measured according to AASHTO T 283 (2022);
- and
- a tensile strength ratio (TSR) of at least 80%, measured according to ASTM D 3625 (2020).
