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).
