DESIGN AND EVALUATION OF ROADWAY WIDENING SECTIONS THROUGH SWAMPS

Six methods of floating roadway widening sections over a peat swamp were designed and constructed on a two lane roadway in 1976. The project location was on T.H. 53 between International Falls and Ray. Peat depths ranged from 8 to 15 feet. The investigation to date has shown that widenings can be floated on peat when fill height and loading rates are controlled. Performance of the sections will be monitored for a period of at least three years.
