This is the second revision of this handbook which was originally written in 1996. This update to the handbook, although still titled Minnesota Seal Coat Handbook, has changed all references of Seal Coat to Chip Seal, better aligning it with other state Department of Transportation's (DOT's), Federal Highway Administration (FHWA), and industry. Minnesota Department of Transportation (MnDOT) specifications will eventually be updated to reflect this change. As preventive maintenance and preservation of bituminous pavements continues to evolve, this version of the handbook has been expanded to include a brief discussion on spray applied bituminous surface seals and additional similar types of thin bituminous pavement surface treatments which are often referred to as BSTs. Although information on the BSTs discussed above have been brought into this handbook, the intent is still the same, to provide guidance in the design and construction of high-quality chip seal surface treatments for bituminous pavements. Applying this treatment to the right pavement at the right time while paying attention to the quality of materials used and workmanship will result in better performing, longer lasting bituminous pavements. This revision of the handbook was sponsored by the MnDOT Pavement Section with assistance from WSB Consulting Engineers and input from a Technical Advisory Panel made up of MnDOT, City and County Engineers.
