The Minnesota Department of Transportation (Mn/DOT) has concluded a research study on the proper techniques involved in seal coating. A key part of the research project involved performing seal coat designs using the procedure developed by Norman McLeod. In addition, research personnel were present on many seal coat construction projects assisting the inspector and contractor. The primary purpose of this handbook, revised in 2006, is to provide a solid background in seal coat materials, equipment, design and construction for the field inspector. Divided into two main sections, this updated handbook provides direction for designers and field personnel. Thomas J. Wood handled this revision. The original work was prepared by David W. Janisch and Frank S. Gaillard.

NOTE: A revised version of Minnesota Seal Coat Handbook was published in December 2022 (report 2022-22).
