Soil classification data for River Bend Crossing test soil bores C-1 through C-5
Text Version
The soil classification data provides information on the soil test bores C-1 through C-5 at the River Bend Crossing site. The top half includes a line chart with the five test bores, showing data for three sets of data points:
- Top axis: U.S. sieve opening in inches, ranging from 3 to 3/8; U.S. sieve numbers ranging from 10 to 200; and hydrometer, with no range indicated
- Left axis: Percent passing by weight, ranging from 0 to 100
- Bottom axis: Grand size in millimeters, ranging from 100 to 0.001, and the following labels running along the same axis:
- Cobbles
- Gravel – Coarse
- Gravel – Fine
- Sand – Coarse
- Sand – Medium
- Sand – Fin
- Silt or clay
The lines run from top left to the bottom right, largely in alignment, from a grain size of 20 millimeters to 0.1, percent from 100 to 0 to 15, and U.S. sieve opening in inches from 1 to 12 to a U.S. sieve number of 200

The lines for R-1, R-2 and R-4 run from top left to the bottom right, largely in alignment, from a grain size of 20 millimeters to 0.1, percent from 100 to 0, and U.S. sieve opening in inches from 3/4 to 1/2 to a U.S. sieve number of 200. R-3 is represented by a single point at the intersection of 0.1 grain size, 80 percent passing by weight and 200 U.S. sieve number. For R-5, it is a single point at the intersection of 0.1 grain size, 55 percent passing by weight and 200 U.S. sieve number.

The lines for R-7 and R-9 run from top left to the bottom right. For R-7, it runs from a grain size of 25 millimeters to 0.1, percent from 100 to 5, and U.S. sieve opening in inches from 1 to a U.S. sieve number of 200. For R-9, it runs from a grain size of 15 millimeters to 0.1, percent from 100 to 5, and U.S. sieve opening in inches from 1/2 to a U.S. sieve number of 200. The other three test soil bores, R-6, R-9 and R-10, are all represented by a single point at the intersection of .01, percent from 85 to 90, and a U.S. sieve number of 200.
