The sieve analysis results of an aggregate sample are provided below. What are the maximum aggregate size and the maximum nominal aggregate size? Using the 0.45 power curve, plot the gradation for the data provided in the table. Indicate whether the gradation is dense-graded, gap-graded, or open-graded.

Transcribed Image Text:The table provided displays the retained mass (in grams) for various sieve sizes, measured in millimeters (mm) and corresponding US standard sieve sizes. This data is typically used in sieve analysis for particle size distribution studies.
| Sieve Size (mm) (US Standard) | Retained Mass (grams) |
|-------------------------------|-----------------------|
| 9.5 (3/8") | 0.0 |
| 4.75 (#4) | 30.2 |
| 2.36 (#8) | 75.4 |
| 1.18 (#16) | 100.5 |
| 0.600 (#30) | 135.0 |
| 0.300 (#50) | 173.0 |
| 0.150 (#100) | 121.9 |
| 0.075 (#200) | 54.0 |
| Pan | 10.0 |
### Explanation of the Data:
- **Sieve Sizes**: The left column lists the sieve sizes in millimeters, accompanied by their US standard designations. These sizes represent the openings of the sieves through which the particles pass.
- **Retained Mass (grams)**: The right column shows the mass of material retained on each sieve after the sieving process. This information is crucial for determining the particle size distribution of a sample.
