Seal coating has been widely used as a cost-effective strategy in asphalt pavement preservation by MnDOT and local agencies to extend the life of pavements. However, some cities and counties in Minnesota have reported concerns about the premature stripping of street pavements that have been seal coated.
To address questions and concerns, the LRRB sponsored a study to review and synthesize previous seal coat research and practices. The researchers developed a reference guide that provides users with quick access to some of the research and resources available in Minnesota. City and county engineers can use it to address questions regarding the pros and cons of seal coats.
