Abstract: Provided herein are antistripping compositions which may be used, for example, as additives to bitumen compositions such as asphalt concrete to prevent or reduce susceptibility to water damage. In particular, the antistripping compositions of the present disclosure have a triamine component and a nitrile component. Also provided herein are bitumen compositions, such as asphalt, having a portion of the described antistripping compositions as an additive.
