About the research
Research objective: Iowa State University is a subcontractor to the University of Minnesota on this national pooled fund study.
ISU researchers will expand a test matrix with additional field samples, develop a low-temperature specification for asphalt mixtures, validate the new specification, and develop draft AASHTO standards.
