This study provides a systematic method for evaluating seal coat treated pavement oxidation and predicting future changes to the binder rheology based onmeasured oxidation kinetics and hardening properties. In the absence of original material, binder extracted and recovered from field cores can be further oxidized in laboratory accelerated aging tests in order to determine oxidation kinetics and hardening parameters for forensics studies. Once these parameters for the pavement binder are known, future pavement oxidation over time can be estimated using pavement oxidation models previously reported. This approach provides a cost-effective strategy for evaluating pavement oxidation and the effectiveness of seal coats.
