Synthesis of Seal Coat Research in Minnesota

Status:  Complete
Report Date:  10/24/2024

Summary:

While seal coating has been widely used as a cost-effective strategy in asphalt pavement preservation by the Minnesota Department of Transportation (MnDOT) and local agencies to extend the life of pavements, some cities and counties in Minnesota have reported their concerns about the premature stripping of street pavements that have been seal coated. The Local Road Research Board earlier completed a study on seal coats titled, "Is Seal Coating Counterproductive or Not?" to address these issues. The purpose of this document is to provide users with quick access to some of the research and resources available in Minnesota.
