Verification and Implementation of Production-Level Long-Term Durability Assessment for Asphalt Mixtures

About the project

The primary purpose of this study is to verify the suitability, practicality, and implementation viability of the recommended production-level long-term oven-aging (LTOA) protocols and associated cracking tolerance (CT) index threshold within VDOT's Balanced Mix Design framework. While the previous research established a practical design-stage LTOA protocol and recommended production-level aging procedures, additional evaluation is needed to confirm that the proposed production protocols and CT index threshold provide a reliable basis for future implementation into statewide production acceptance and quality assurance practices.
