Description: Technical Report
Summary: A limited program of trafficability tests with four vehicles (a 20-in.-track Weasel, a 10-in.-track Weasel, a Water Buffalo, and a Dinah) was conducted in eight confined muskeg areas in Ontario, Canada. Frequent failures of mechanical components of the vehicles because of muskeg clogging the track systems hampered the test program. Results showed the cone penetrometer and shear vane to have promise as tools for measuring trafficability of muskeg. The standard Weasel (with 20- in.-wide tracks) could negotiate the relatively dense muskeg but was immobilized on the floating-mat type (mechanical failures excluded). The Weasel equipped with special, 10-in.-wide tracks had occasional difficulty even in the more consolidated hogs. Towing abilities of the Weasels were nearly 100% of their weights. In addition to the self-propelled and towing tests of the Weasels, four self-propelled tests were conducted with a Water Buffalo, and two with a Dinah. On a qualitative basis, ranges of trafficability potential were disclosed in the tests, and these were tentatively related to characteristic differences in peat, cover, and terrain-water relations. Additional tests need to be conducted in the same areas with a range of vehicle types before acceptable correlations between vehicle performance and muskeg type and condition can be expressed.
