Underseals
Underseals, often referred to as Texas underseals because of their origin there, are being used in other regions, including Minnesota. However, their use has been limited and relatively undocumented. A few agencies in Minnesota, such as Hennepin County, City of Eden Prairie, and City of Lakeville, have implemented underseals on select projects. The objective of this project was to survey Minnesota and neighboring state agencies - using Minnesota Department of Transportation's (MnDOT’s) National Road Research Alliance network to develop a database of bituminous underseal projects. The study aimed to synthesize information on usage, cost, timing, benefits, drawbacks, and performance.
