Review of Relationships between Modified Asphalt Properties and Pavement Performance

摘要

The literature review was initiated to better understand the effects of asphalt modifiers on pavement performance. The objective was to collect and to summarize information in the technical literature as of November 1990 which relates modified asphalt properties (both chemical and physical) to field pavement performance with a goal to identify any consensus in the technical literature regarding relationships between modified asphalt binder properties and pavement performance. Modifiers under consideration include fillers, fibers, extenders, polymers, plastics, anti-strip agents, oxidants and reclaimed rubber. Pavement performance measurements of interest were those investigated by Project A-003A; namely fatigue cracking, rutting, thermal cracking, aging, and water sensitivity.
