Abstract:
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 State’s highways that cause potential safety issues for vehicular traffic. The damage includes breaking off bits of the pavement’s 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® 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 State’s

highways. Recommendations include:

1. Adoption of a revised Motorized Recreational Vehicle Trail Crossing detail for use in permitting new trail crossings.

2. Improvement of existing trail crossings to bring them into reasonable compliance with the Motorized Recreational Vehicle Trail

Crossing detail.

3. A statewide program for treating, improving and maintaining snowmobile crossings in collaboration with the recreational vehicle

community.
