Two line charts showing the swell consolidation rest results at the River Bend Cross site

Text Version

The swell/consolidation test results shows two line charts, mapped with a horizontal axis labeled Applied Pressure – PSF ranging from 100 to 105, and a vertical axis labeled compressions percentage expansion ranging from -7 to 3.

Top chart

The top chart shows a line graph, starting at the intersection of applied pressure of approximately 250 and compression percentage expansion of 0, running to an applied pressure of 1,000 and compression percentage of -0.5, then jumping to a compression percentage of 2.5, and then running to point beyond 10,000 applied pressure and a compression percentage of -1. The text underneath this chart reads:

  • Project: 5680 U.S. Highway 85/87, Fountain, Colorado
  • Sample description: Claystone, Silty
  • Note: Sample was inundated with water at 1,000 PSF
  • Sample location: R08 at 9 feet
  • Natural dry unit weight: 105.2 PCF
  • Natural moisture content: 23.0%
  • Percent swell/compression: 3.0

Bottom chart

The bottom chart shows a line chart, starting at the intersection of applied pressure at approximately 250 and a compression percentage expansion of 0, gradually moving to the bottom right with an applied pressure of 3,000 and a compression percentage expansion of -7.
