FHWA-funded doctoral research

Asphalt–polymer compatibility framework

Identify recycled and commercial polymers that can blend with asphalt without phase separation.

01 / Context

Problem

Identify recycled and commercial polymers that can blend with asphalt without phase separation.

02 / Method

Approach

Designed all-atom LAMMPS simulations, formulated a Flory-Huggins interaction framework and validated simulated mixing with FTIR.

03 / Toolkit

Tools & methods

LAMMPSOPLS-AAFlory-Huggins analysisFTIR

04 / Result

Outcome

Established a compatibility ranking for pre-screening blends before laboratory and field trials; the framework has been applied by an independent research group and an industry engineer.
