摘要：	Excessive highway pavement wear from snowmobile traffic is a maintenance problem for the New Hampshire Department of Transportation. The snowmobiles and trail grooming equipment scar and erode the pavement surfaces, eventually creating wide ruts across the States highways that cause potential safety issues for vehicular traffic. The damage includes breaking off bits of the pavements edge until the travel lanes are threatened. The Department performed an evaluation of alternative pavement treatments intended to protect the pavement surface from excessive degradation. Cleanosol is a surface-applied thermoplastic material that has been successfully used to armor snowmobile crossings in Michigan and Wisconsin. Imprint(TradeName) is a synthetic surface material developed in the United Kingdom that consists of a hot applied resinbased compound with graded sand and granite aggregate, reinforced with two (2) types of fibers. Three pairs of snowmobile crossings, known for heavy snowmobile traffic and excessive pavement wear, were treated with each product. Wear was measured and patterns were observed over three winters. Unit wear rates of the test materials did not indicate a greater durability than conventional hot mix asphalt. Cleanosol was the easiest and quickest product to install, and was the least expensive as compared with Imprint and HMA repair. The convenience and lower cost of installing Cleanosol make it a good choice for the repair of snowmobile trail damage across the States highways. / Title Note: Final rept. / Supplementary Notes: Sponsored by Federal Highway Administration, Concord, NH.
