TRB's National Cooperative Highway Research Program (NCHRP) Research Report 847: Variability of Ignition Furnace Correction Factors explores the significant influences that affect the variability of asphalt and aggregate correction factors for ignition furnaces. The report presents a proposed practice in American Association of State Highway and Transportation Officials (AASHTO) standard format for installation, operation, and maintenance of ignition furnaces to minimize the variability in correction factors between furnaces.
