Sieve Analysis of Soil; Its Determination, Theory

Grading curves with the ordinates representing cumulative percentage passing and the abscissa the sieve opening to logarithmic scale can be drawn to study the results of sieve analysis of soil. By using these curves, it is possible to see whether the grading of a given sample conforms to that specified or is too course or too fine, or deficient in a particular size.

Influence of Gradation on Resilient Modulus of

Because of low resilient modulus, high plasticity soil is often not allowed to fill road subgrades and is discarded as construction and demolition waste (CDW). To make use of the CDW, this study explored the possibility of improving high plasticity soil with gravel and examined the effect of gravel gradation on the resilient modulus of the soil-gravel mixture.
