A composition comprising bitumen and products obtained by reacting a resin with an amine.
A composition comprising bitumen, polymer, and products obtained by reacting a rosin ester with an amine, wherein said products comprise an alcohol and an amide.
A method of incorporating polymer into a bitumen emulsion comprising the steps of:
- combining bitumen, polymer, resin and amine to form a pre-mix;
- heating the pre-mix to a temperature sufficient to react the resin and the amine to form reaction products;
- and
- mixing the reacted pre-mix with a bitumen emulsion.
A method of reducing the viscosity of a composition comprising bitumen and polymer, the method comprising the steps of:
- adding a resin and an amine to the composition;
- and
- reacting the resin and the amine to form reaction products, the reaction products comprising a viscosity reducer.
A composition comprising bitumen, polymer and products obtained by reacting a resin with an amine, wherein low shear mixing of said bitumen, polymer and products forms a stable bitumen emulsion.
