Enhancing asphalt's properties with a bio-based polymer modified liquid asphalt cement

A composition comprising:

• a polymer comprising two or more units of monomer A, with monomer A being a radically polymerizable plant oil, animal oil, synthetic triglyceride, or mixture thereof;
• an epoxidized vegetable oil, an epoxidized fatty acid, or an epoxidized fatty ester;
• an asphalt polymer modifier;
• a cross-linker;
• and
• an asphalt portion.

A method of producing a liquid cement composition comprising:

• providing a polymer comprising two or more units of monomer A, with monomer A being a radically polymerizable plant oil, animal oil, synthetic triglyceride, or mixture thereof;
• providing an epoxidized vegetable oil, an epoxidized fatty acid, or an epoxidized fatty ester;
• and
• mixing the polymer with the epoxidized vegetable oil, the epoxidized fatty acid, or the epoxidized fatty ester to produce a liquid cement composition.
