Abstract:

The largest commercially available disc saws 7 ft diameter were tested in frozen ground. Cutting performance was reasonably attractive, specific energy consumption was acceptable, but cutter durability in frozen gravel was judged to be totally inadequate. A new cutter system was developed for the saw that provided best general capabilities, and a dramatic improvement in cutter durability was achieved. The modified saw cut slots 3.7 in. wide and 30 to 34 in. deep at rates up to 6.6 ftmin in coarse frozen gravel and up to 16.3 ftmin in frozen silt.
