NCHRP 09-63 Project Update: A Calibrated and Validated National Performance-Related Specification for Emulsified Asphalt Binder Greg Harder AASHTO TSP•2 – Emulsion Task Force (ETF) Meeting Heritage Research Group – The Center Indianapolis, IN June 12-13, 2019
Project Objectives Develop a national performance-related material specification for emulsified asphalt binder for use with chip seals and microsurfacing/slurry seals that: is similar in concept and format to AASHTO Standard Specifications M320 and M332; is calibrated and validated with performance data from field test sections; uses readily available testing equipment (i.e., Superpave test equipment); and reflects varying climatic and traffic conditions.
ETF Draft Specification will be used as the starting point Project Objectives Develop a national performance-related material specification for emulsified asphalt binder for use with chip seals and microsurfacing/slurry seals that: is similar in concept and format to AASHTO Standard Specifications M320 and M332; is calibrated and validated with performance data from field test sections; uses readily available testing equipment (i.e., Superpave test equipment); and reflects varying climatic and traffic conditions.
