NCHRP Implementation Support Program. Implementation of NCHRP Project 09-65: Capturing Durability of High Recycled Binder Ratio (RBR) Asphalt Mixtures

NCHRP Project 09-65, “Capturing Durability of High Recycled Binder Ratio (RBR) Asphalt Mixtures” was initiated to (1) develop a proposed American Association of State Highway and Transportation Officials (AASHTO) standard practice and associated test methods for designing and evaluating durable asphalt mixtures with high recycled asphalt materials (RAM) content and (2) revise the proposed AASHTO Standard Practice for Characterizing Asphalt Mixtures with High Recycled Materials Contents and Recycling Agents. The final report for NCHRP Project 09-65 was published as NCHRP Research Report 1130: Capturing the Durability of High Recycled Binder Ratio Asphalt Mixtures. It presents a stepwise approach and strategies for developing durable asphalt mixtures with a high recycled binder ratio (RBR). These strategies were derived from extensive laboratory experiments involving various virgin binders, aggregates, recycled asphalt materials, and additives. The laboratory work was complemented by performance modeling to assess resistance to fatigue loading after aging and moisture conditioning. To effectively implement the findings of NCHRP Research Report 1130, it is essential to actively disseminate the research results and develop a comprehensive training program. By integrating these findings into a structured training course, practitioners can gain the expertise needed to support adoption and eventual inclusion in standard practice. OBJECTIVE: The objective of this project is to develop and deliver a comprehensive training program for state departments of transportation (DOTs) to ensure the effective adoption and implementation of the research findings from NCHRP Research Report 1130.
